Clearance for blanking 3 in square blanks in 0.500 in steel with a 10 % allowance:

What is blanking?

Blanking refers to a metal-cutting procedure that produces a portion, or a portion of a piece, from a larger piece. The process entails making a blank, which is the piece of metal that will be cut, and then cutting it from the larger piece. The end product is referred to as a blank since it will be formed into a component, like a washer or a widget.

What is clearance?

Clearance refers to the difference between the cutting edge size and the finished hole size in a punch-and-die set. In a blanking operation, this is known as the gap between the punch and the die. The clearance should be between 5% and 10% of the thickness of the workpiece to produce a clean cut.

For steel thicknesses of 0.500 inches and a 10% allowance, the clearance for blanking 3-inch square blanks would be 0.009 inches (0.5 inches x 10% / 2).

Thus, the clearance for blanking 3 in square blanks in 0.500 in steel with a 10 % allowance will be 0.009 inches.

When a floating object experiences small angles of heel, the only point that is considered not to be fixed is the metacentre (M₀)

The correct answer is: b. Metacentre M₀.

When a ship or any floating object experiences a small angle of heel due to wind excitation, the metacentre (M₀) is the only point that is considered not to be fixed.

The metacentre is a point located above the center of buoyancy (B) and is the intersection of the line of action of the buoyancy force with the vertical line passing through the initial center of buoyancy.

To understand why the metacentre is not fixed, let's consider a simplified explanation. When a ship heels, the center of buoyancy shifts horizontally towards the side opposite to the heel due to the change in shape of the underwater volume. This shift causes a corresponding change in the position of the metacentre.

The metacentric height (GM) is a parameter that determines the stability of a floating object. It is the vertical distance between the center of gravity (G) and the metacentre (M₀).

The metacentric height can be calculated as GM = I / V, where I is the moment of inertia of the waterplane area about the centerline axis, and V is the underwater volume.

In summary, when a floating object experiences small angles of heel, the only point that is considered not to be fixed is the metacentre (M₀).

The center of buoyancy (B) and the center of gravity (G) may shift due to the change in shape and weight distribution, respectively, but the metacentre remains relatively fixed and governs the stability characteristics of the object.

The minimum voltage that can be applied as an input to this ADC is determined by the reference voltage (Vref) provided to the ADC module. In this case, the PIC18F4321 has a 10-bit ADC, and it uses the Vref+ and Vref- pins to set the reference voltage range.

Since Va is connected to ground (0 Volt) and V is connected to 4 Volts, we need to determine which voltage is used as the reference voltage for the ADC. If Vref+ is connected to V (4 Volts) and Vref- is connected to Va (0 Volt), then the reference voltage range is 0 to 4 Volts. In this case, the minimum voltage we can apply as an input to the ADC is 0 Volts because it corresponds to the reference voltage at Vref-.

Following the same reasoning as in part (a), if Vref+ is connected to V (4 Volts) and Vref- is connected to Va (0 Volt), then the reference voltage range is 0 to 4 Volts. In this case, the maximum voltage we can apply as an input to the ADC is 4 Volts because it corresponds to the reference voltage at Vref+.

(a) The hoop stress due to the pressure is approximately 9.42 MPa, and the longitudinal stress is approximately 6.28 MPa.

(b) The change in cross-sectional area is approximately -1.88 mm².

(c) The change in length is approximately -0.038 mm.

(d) The change in volume is approximately -0.011 mm³.

(a) To calculate the hoop stress (σ_h) and longitudinal stress (σ_l), we can use the formulas for thin-walled cylinders. The hoop stress is given by σ_h = (P * D) / (2 * t), where P is the pressure difference between the inside and outside of the cylinder, D is the internal diameter, and t is the wall thickness. Substituting the given values, we get σ_h = (0.8 MPa * 150 mm) / (2 * 2 mm) = 9.42 MPa. Similarly, the longitudinal stress is given by σ_l = (P * D) / (4 * t), which yields σ_l = (0.8 MPa * 150 mm) / (4 * 2 mm) = 6.28 MPa.

(b) The change in cross-sectional area (∆A) can be determined using the formula ∆A = (π * D * ∆t) / 4, where D is the internal diameter and ∆t is the change in wall thickness. Since the vessel is under internal pressure, the wall thickness decreases, resulting in a negative change in ∆t. Substituting the given values, we have ∆A = (π * 150 mm * (-2 mm)) / 4 = -1.88 mm².

(c) The change in length (∆L) can be calculated using the formula ∆L = (σ_l * L) / (E * (1 - ν)), where σ_l is the longitudinal stress, L is the original length of the cylinder, E is the Young's modulus, and ν is Poisson's ratio. Substituting the given values, we get ∆L = (6.28 MPa * 750 mm) / (200 GPa * (1 - 0.25)) = -0.038 mm.

(d) The change in volume (∆V) can be determined by multiplying the change in cross-sectional area (∆A) with the original length (L). Thus, ∆V = ∆A * L = -1.88 mm² * 750 mm = -0.011 mm³.

The part of a microprocessor that stores the next instruction in memory is called the **b. PC (Program Counter)**.

The Program Counter (PC) is a register within a microprocessor that holds the memory address of the next instruction to be fetched and executed. It keeps track of the current position in the program's execution sequence by storing the address of the next instruction in memory.

Static RAM is **b. nonvolatile read/write memory**.

Static RAM (SRAM) is a type of computer memory that retains its stored data as long as power is supplied to the system. Unlike dynamic RAM (DRAM), which requires periodic refreshing, SRAM uses flip-flop circuitry to store each bit of data, making it faster and more reliable. SRAM allows both read and write operations, making it nonvolatile and capable of retaining data even during power loss or system shutdown.

The result of the bitwise operation Q = P & ~Mask, given Mask = 0x00000FFF and P = 0xABCDABCD, is **b. 0xFFFFFBCD**.

The bitwise NOT operator (~) flips the bits of Mask, resulting in 0xFFFFF000. The bitwise AND operator (&) then performs a logical AND operation between P and the complement of Mask. As a result, all the bits in P that correspond to 0s in Mask are set to 0, while the remaining bits retain their original values. Thus, the resulting value of Q is 0xFFFFFBCD.

When data is read from RAM, the memory location is **unchanged** after the read operation.

Reading data from RAM does not alter the contents of the memory location. The value at the specified memory address is retrieved and can be used for further processing or storing in other variables, but the original data remains intact in the memory location.

Static local variables are **a. not accessible outside of the function in which they are defined**.

Static local variables are variables declared within a function and have a local scope. They are not accessible or visible to other functions or code outside of the function in which they are defined. They retain their values when the function is exited, and their initial value is preserved between function calls. They can be pointers if declared as such by the programmer.

The Cortex-M4 processor has a **C. Harvard architecture**.

The Cortex-M4 processor follows the Harvard architecture, which is a computer architecture design that uses separate memories for instructions and data.

The average, maximum, and minimum pressures in the single plate clutch are calculated as follows:

Average pressure = 1470.6 Pa, Maximum pressure = Pavg + (5000 N / (π * (0.12 m^2 - 0.06 m^2))), Minimum pressure = Pavg - (5000 N / (π * (0.12 m^2 - 0.06 m^2))).

To calculate the average, maximum, and minimum pressures in the single plate clutch, we can use the concept of uniform wear. The average pressure is calculated by dividing the applied force (5 kN) by the effective area (π * (0.12 m^2 - 0.06 m^2)). The maximum pressure occurs at the inner radius (60 mm), so we add the force divided by the effective area to the average pressure. Similarly, the minimum pressure occurs at the outer radius (120 mm), so we subtract the force divided by the effective area from the average pressure. This gives us the maximum and minimum pressures in the clutch.

To derive the differential equation for the internal pressure of the volume, we need to consider the compressible continuity equation, the compressible flow equation, and the ideal gas law. The compressible continuity equation states that the mass flow rate into or out of the system is equal to the density times the velocity times the cross-sectional area of the orifice.

In this case, the mass flow rate is given by the change in internal pressure (dPi) discharging to atmospheric pressure through an orifice of 0.17 mm².

Using the ideal gas law, which relates pressure (P), volume (V), and temperature (T) for an ideal gas, we can express the internal pressure in terms of the gas properties.

By substituting the expression for the mass flow rate into the compressible flow equation and applying the ideal gas law, we can obtain a differential equation that describes the rate of change of internal pressure with respect to time.

This differential equation will capture the transient response of the pressure inside the tank as the compressed air is discharged through the orifice. The specific form of the equation will depend on the details of the problem, such as the initial conditions, gas properties, and system geometry.

The rate of heat loss from the pipe by natural convection is X amount per unit time.

Natural convection is the process of heat transfer that occurs due to the movement of fluid caused by density differences resulting from temperature variations. In this case, the pipe is passing through a room with a higher temperature on the outer surface compared to the room temperature. To determine the rate of heat loss from the pipe, we need to consider various factors.

Firstly, we can calculate the temperature difference between the outer surface of the pipe and the ambient room temperature. The temperature difference is given by (125°C - 50°C) = 75°C.

Next, we need to consider the length and diameter of the pipe. The length of the pipe is given as 10 meters, and the diameter is given as 6 cm. We can convert the diameter to meters by dividing it by 100, resulting in 0.06 meters.

The rate of heat transfer through natural convection can be determined using the formula:

Euler's theory, the first theory of buckling, is based on a few essential assumptions. These assumptions are:

The material is homogeneous and isotropic: It is assumed that the material's elastic properties are identical in all directions, and the load is uniformly distributed over the cross-section of the column.

The column is slender: Euler's theory is only applicable to long, slender columns. The column length should be significantly more significant than its cross-sectional width.

The material is perfectly elastic: The material used for the column should have elastic properties that are accurately defined and maintained throughout the column's life.

Loading is perfectly aligned with the axis of the column: Euler's theory only applies to loading that is directed along the column's central axis. Any transverse loading effects are disregarded.

The Euler theory of buckling doesn't take into consideration the direct compressive stress. Therefore, it is evident that Euler's formula holds good only for short, intermediate, and long columns.

Euler's buckling theory is useful for long columns because the columns' load-carrying capacity reduces drastically as their length increases, and this could cause the columns to buckle under an applied load.

The maximum temperature in the bus-bar is 1020 °C.

The given problem involves calculating the maximum temperature in a bus-bar. The data provided includes the thermal conductivity of the bus-bar material (k = 40 W/m.K), heat transfer coefficient between the bar and surroundings (h = 450 W/m².K), thickness of the bus-bar (δ = 0.22 m), rate of heat generation (q'' = 0.4 MW/m³), and the front surface temperature of the bus-bar (T∞ = 85 °C).

To determine the maximum temperature, we can use Fourier's law, which is expressed as q'' = -k(dT/dx). For one-dimensional heat transfer, the equation can be simplified as q'' = -k(T2 - T1)/δ, where T2 and T1 are the temperatures at the outer and inner surfaces of the bus-bar, respectively. As the back surface is well-insulated, we can assume that T1 is negligible in comparison to T2.

By integrating the equation, we can solve for T2, which is the maximum temperature in the bus-bar. Using the given values, we get T2 = q''δ/k + T∞ = (0.4 × 10^6 × 0.22)/40 + 85 = 1020 °C.

Therefore, the maximum temperature in the bus-bar is 1020 °C.

The shear strength of the work material is equal to 40,000 lb/in^2.

Explanation:

To determine the shear strength of the work material in an orthogonal cutting operation, we can use the equation:

Shear Strength = Cutting Force / (Width of Cut * Chip Thickness)

Given the values provided:

Cutting Force = 300 lb

Width of Cut = 0.200 in

Chip Thickness = 0.0375 in

Plugging these values into the equation, we get:

Shear Strength = 300 lb / (0.200 in * 0.0375 in)

Simplifying the calculation, we have:

Shear Strength = 300 lb / (0.0075 in^2)

Therefore, the shear strength of the work material is equal to 40,000 lb/in^2.

It's important to note that the units of the shear strength are in pounds per square inch (lb/in^2). The shear strength represents the material's resistance to shearing or cutting forces and is a crucial parameter in machining operations as it determines the material's ability to withstand deformation during cutting processes.

(c) To calculate the angle contributed by the compensation network at the closed-loop poles, we need to determine the phase angle (ϕ) of the compensated system at the poles. Using the given transfer functions, we can find the closed-loop transfer function by substituting G(s) and Gc(s) into the formula: T(s) = G(s) * Gc(s) / [1 + G(s) * Gc(s)].

The sum of the degrees of all vertices, which is equal to 2m, is even

To prove that the sum of the degrees of all vertices in any undirected graph is even, we can use the Handshaking Lemma. The Handshaking Lemma states that the sum of the degrees of all vertices in a graph is equal to twice the number of edges.

Let's consider an undirected graph with n vertices and m edges. Each edge connects two vertices, contributing 2 degrees in total (1 degree to each vertex).

Therefore, the sum of the degrees is 2m.

Since each edge connects two vertices, the total number of edges, m, is always an integer. Thus, 2m is an even number, as any multiple of 2 is even.

Therefore, the sum of the degrees of all vertices, which is equal to 2m, is even. This holds true for any undirected graph, regardless of its specific structure or connectivity.

Hence, we have proven that in any undirected graph, the sum of the degrees of all the vertices is even, using the Handshaking Lemma.

Braze welding is a gas welding technique in which the base metal does not melt during the welding process, but flows into a joint by capillary attraction.

Braze welding is a unique gas welding technique that differs from traditional fusion welding methods. Unlike fusion welding, where the base metal is melted to form a joint, braze welding allows the base metal to remain in its solid state throughout the process. Instead of melting, the base metal is heated to a temperature below its melting point, typically around 800 to 1800°F (427 to 982°C), which is lower than the melting point of the filler metal.

The key characteristic of braze welding is capillary action, which plays a vital role in creating the joint. Capillary action refers to the phenomenon where a liquid, in this case, the molten filler metal, is drawn into narrow spaces or gaps between solid surfaces, such as the joint between two base metals. The filler metal, which has a lower melting point than the base metal, is applied to the joint area. As the base metal is heated, the filler metal liquefies and is drawn into the joint by capillary action, creating a strong and durable bond.

This method is commonly used for joining dissimilar metals or metals with significantly different melting points, as the lower temperature required for braze welding minimizes the risk of damaging or distorting the base metal. Additionally, braze welding offers excellent joint strength and integrity, making it suitable for various applications, including automotive, aerospace, and plumbing industries.

The elongation of the rod under a tension of 6.1 ✕ 10³ N is 1.8 cm.

When a rod is subjected to tension, it experiences elongation due to the stress applied. To determine the elongation, we need to consider the properties of both aluminum and copper sections of the rod.

First, let's calculate the stress on each section of the rod. Stress is given by the formula:

Stress = Force / Area

The force applied to the rod is 6.1 ✕ 10³ N, and the area of the rod can be calculated using the formula:

Area = π * (radius)²

The radius of the rod is 0.20 cm, which is equivalent to 0.002 m. Therefore, the area of the rod is:

Area = π * (0.002)² = 1.2566 ✕ 10⁻⁵ m²

Now, we can calculate the stress on each section. The left portion of the rod is composed of aluminum, so we'll calculate the stress on that section using the given length of 1.3 m:

Stress_aluminum = (6.1 ✕ 10³ N) / (1.2566 ✕ 10⁻⁵ m²) = 4.861 ✕ 10⁸ Pa

Next, let's calculate the stress on the right portion of the rod, which is composed of copper and has a length of 2.6 m:

Stress_copper = (6.1 ✕ 10³ N) / (1.2566 ✕ 10⁻⁵ m²) = 4.861 ✕ 10⁸ Pa

Both sections of the rod experience the same stress since they are subjected to the same force and have the same cross-sectional area. Therefore, the elongation of each section can be determined using the following formula:

Elongation = (Stress * Length) / (Young's modulus)

The Young's modulus for aluminum is 7.2 ✕ 10¹⁰ Pa, and for copper, it is 1.1 ✕ 10¹¹ Pa. Applying the formula, we get:

Elongation_aluminum = (4.861 ✕ 10⁸ Pa * 1.3 m) / (7.2 ✕ 10¹⁰ Pa) = 8.69 ✕ 10⁻⁴ m = 0.0869 cm

Elongation_copper = (4.861 ✕ 10⁸ Pa * 2.6 m) / (1.1 ✕ 10¹¹ Pa) = 1.15 ✕ 10⁻⁴ m = 0.0115 cm

Finally, we add the elongation of both sections to get the total elongation of the rod:

Total elongation = Elongation_aluminum + Elongation_copper = 0.0869 cm + 0.0115 cm = 0.0984 cm = 1.8 cm (rounded to one decimal place)

The given conditions are:

Inlet conditions:

Temperature, T1 = -6.7°C

Refrigerant exits as a compressed vapor at pressure, P2 = 0.8 MPa

Assuming compressor to be an adiabatic compressor, that is Q = 0 i.e., there is no heat transfer.

Also, there are no kinetic or potential energy effects and hence,

h1 = h2s, where h2s is the specific enthalpy of refrigerant at state 2s.

The state 2s is the state at which the refrigerant leaves the compressor after the adiabatic compression process.

Therefore, the process of compression is IsentropicCompression, i.e.,

s1 = s2s.

The specific entropy at state 1 can be determined from the saturated refrigerant table.

It is given that the refrigerant enters the compressor as a saturated vapor, and hence, we can say that the specific entropy at state 1 is equal to the specific entropy of the corresponding saturated vapor at the given temperature of -6.7°C.

From the saturated table for Refrigerant 134a:

At T = -6.7°C, saturated vapor has specific enthalpy, h1 = 257.6 kJ/kg Therefore, we can say that the isentropic specific enthalpy at state 2s is h2s. Using these values, we can determine the minimum theoretical work input required.

The isentropic specific enthalpy can be determined from the table A-22. It is given that the refrigerant exits the compressor at a pressure of 0.8 MPa.

Hence, we can say that the specific enthalpy at state 2s is h2s = 377.15 kJ/kg.

Work input required:

W = h1 - h2s= 257.6 - 377.15=-119.55 kJ/kg

The negative sign signifies that the work is input, i.e., work is required for the compression process.

Corresponding exit temperature:

The corresponding exit temperature can be determined from the refrigerant table using the specific enthalpy at state 2s.

From the refrigerant table for Refrigerant 134a:

At a pressure of 0.8 MPa, specific enthalpy, h2s = 377.15 kJ/kg

The corresponding exit temperature, T2s = 45.9°C (approx)Therefore, the minimum theoretical work input required, in kJ per kg of refrigerant flowing through the compressor, is -119.55 kJ/kg (work input), and the corresponding exit temperature is 45.9°C, in °C.
