To keep track of the number of tape lengths measured while surveying a course, a reel is typically used. The reel allows for the tape to be smoothly unwound and rewound, making it easier to keep track of the length measured.
Additionally, line pins may be used to mark the end of each tape length, ensuring that the surveyor does not lose count. Plumb-bobs are used to ensure that the tape is hanging vertically and not sloping, but they do not help keep track of the number of tape lengths. Range poles are used to measure vertical distances, while bar scales are used to measure map distances. The tool used to keep track of the number of tape lengths measured while surveying a course is called a "reel". A reel is a device that is used to store a measuring tape when it is not in use and also allows for easy deployment and retrieval of the tape during measurement. Line pins are used to mark points on the ground or on a surveying line, while plumb-bobs are used to ensure that a vertical line is established.

Some researchers have suggested replacing the metaphor "glass ceiling" with a "labyrinth" because ______.
A. a labyrinth suggests an easy way forward for women in the professional workplace
B. a glass ceiling was considered a racist term and fell out of favor in the 1990s
C. ceiling implies a single common barrier whereas a labyrinth connotes a more complex journey
D. male managers were also facing barriers at work and wanted to change the terminology
Answer: C
Explanation:
For me, this was process of elimination and deduction, as A would make no sense. A labyrinth is not easy to find your way through. B: This would be the next best option, but since the "glass ceiling" applies to all women and NOT just minorities, that doesn't make a lot of sense. Also, I couldn't find evidence online about the term ever being considered racist. C: a glass ceiling is a universal challenge for everyone (seems like you break through once), while in a labyrinth, there are challenges at every turn, and it's much more complex and confusing. For D, the men could have chosen another word; a labyrinth is intrinsically more complex than a glass ceiling, and I don't think, given the amount of better-suiting options for men, that that one would have been chosen.
Please keep in mind that this is speculation, but I do think C is the answer. Hope this helps!

what common stress state would you expect to exist in a blown-up baloon? hydrostatic compression biaxial tension simple compression torsion simple tension
The common stress state that you would expect to exist in a blown-up balloon is hydrostatic compression.
When air is blown into a balloon, it fills the space inside and exerts pressure on the walls of the balloon equally in all directions. This causes the balloon to experience a hydrostatic stress state, which means that the stress is uniform and equal in all directions. The balloon will resist this pressure by creating internal forces that oppose the outward pressure of the air.
So, in summary, the stress state in a blown-up balloon is hydrostatic compression due to the uniform pressure exerted by the air inside.

A compression member of 1.5-m effective length consists of a solid 30-mm-diameter brass rod. To reduce the weight of the member by 25%, the solid rod is replaced by a hollow rod of the cross section shown. Determine (a) the percent reduction in the critical load, (b) the value of the critical load for the hollow rod. Use E = 200 GPa.
To determine the percent reduction in the critical load and the value of the critical load for the hollow rod, we can use the Euler buckling formula for compression members.
The Euler buckling formula is given by:
Pcr = (π^2 * E * I) / (L^2)
where Pcr is the critical load, E is the modulus of elasticity, I is the moment of inertia of the cross-section, and L is the effective length of the member.
(a) To calculate the percent reduction in the critical load, we need to compare the critical loads of the solid and hollow rods. Let's denote the critical load of the solid rod as Pcr_solid and the critical load of the hollow rod as Pcr_hollow. The percent reduction in the critical load is given by:
Percent reduction = (Pcr_solid - Pcr_hollow) / Pcr_solid * 100
(b) To calculate the value of the critical load for the hollow rod, we need to determine the moment of inertia of the hollow cross-section. The moment of inertia of a hollow circular section can be calculated as:
I = π/64 * (D_outer^4 - D_inner^4)
where D_outer is the outer diameter and D_inner is the inner diameter of the cross-section.
Once we have the moment of inertia for the hollow cross-section, we can substitute the values into the Euler buckling formula to find the critical load Pcr_hollow.
Given the values of E = 200 GPa, L = 1.5 m, and a 25% reduction in weight, we need the specific dimensions of the hollow cross-section (outer and inner diameters) to proceed with the calculations.

why do power companies start jumping up and down when power factor is low
Power factor is a crucial aspect to consider in power systems, as it measures the efficiency of electrical energy usage. It is the ratio of real power to apparent power and typically ranges between 0 and 1.
When the power factor is low, it indicates that a large portion of the electrical power drawn by loads is not being effectively used to perform actual work, leading to wasted energy. This inefficiency can result in higher energy bills, increased strain on electrical infrastructure, and the need for additional capacity to meet demand. Power companies are concerned about low power factors because they lead to:
Increased power losses in transmission lines and equipment, reducing system efficiency.Reduced capacity of the electrical system, requiring costly infrastructure upgrades.Greater demand for reactive power, which may necessitate the installation of expensive power factor correction equipment.Potential penalties for industrial and commercial customers who maintain a consistently low power factor, leading to customer dissatisfaction.Power companies emphasize the importance of maintaining a high power factor to ensure efficient energy usage, reduce strain on the electrical grid, and minimize costs for both the utility and customers.

we need to reduce the speed of a 10-hp electric motor from 1,750 rpm to 500 rpm using a v-belt system. determine possible pulley sizes if a belt surface speed of about 1,800 ft/min is desired.
To determine the possible pulley sizes for reducing the speed of the electric motor, we can use the formula for belt speed:
Belt Speed = π * D * N
Where:
Belt Speed is the desired belt surface speed in feet per minute (ft/min),
D is the diameter of the pulley in inches,
N is the speed of the pulley in revolutions per minute (rpm), and
π is a mathematical constant approximately equal to 3.14159.
First, let's convert the desired belt surface speed from ft/min to inches per minute (in/min) by multiplying by 12:
Desired Belt Speed = 1,800 ft/min * 12 in/ft = 21,600 in/min.
Next, let's calculate the speed ratio, which is the ratio of the motor speed to the desired speed:
Speed Ratio = 1,750 rpm / 500 rpm = 3.5.
Since we want to reduce the speed, the speed ratio will be greater than 1.
Now, let's consider the possible combinations of pulley sizes that will achieve the desired speed ratio. We can choose different pulley sizes for the motor and driven pulleys. The speed ratio is equal to the ratio of the driven pulley diameter to the motor pulley diameter.
We can start by selecting a motor pulley diameter and then calculate the corresponding driven pulley diameter using the speed ratio equation. Here are a few examples:
Example 1: Motor Pulley Diameter = 10 inches
Driven Pulley Diameter = Motor Pulley Diameter / Speed Ratio = 10 inches / 3.5 = 2.857 inches.
Example 2: Motor Pulley Diameter = 8 inches
Driven Pulley Diameter = Motor Pulley Diameter / Speed Ratio = 8 inches / 3.5 = 2.286 inches.
Example 3: Motor Pulley Diameter = 6 inches
Driven Pulley Diameter = Motor Pulley Diameter / Speed Ratio = 6 inches / 3.5 = 1.714 inches.
You can choose different combinations of pulley sizes that satisfy the speed ratio and also ensure that the pulley sizes are readily available in the market.

if a silicon diode is connected in reverse bias to a 1000 ohm resistor with a 4 voltage supply, what is the voltage appearing across the diodes
In a reverse-biased diode, the current flowing through the circuit is negligible and can be assumed to be zero.
Therefore, the voltage appearing across the diode is equal to the supply voltage of 4 volts. This is because the diode acts as an open circuit when reverse biased, allowing no current to flow through it. The voltage drop across the resistor is determined by Ohm's Law, which states that the voltage drop is equal to the product of the current and the resistance. Since the current is zero in this case, there is no voltage drop across the resistor and the full 4 volts appears across the diode.

A 60Hz, 0.5-HP single-phase motor in a washing machine (120V RMS) has an efficiency of 78% at full load (rated output power) and a power factor of 0.72 lagging.
To find the line current, first determine the real power (P) using the formula P = HP × 746, where HP is 0.5. This gives P = 373W. Since efficiency is 78%, the input power (Pin) is P/0.78 = 478.21W. Now, use the power factor (0.72) to find the apparent power (S) by dividing Pin by the power factor: S = 478.21/0.72 = 664.18 VA. To find the line current (I), divide the apparent power (S) by the voltage (120V): I = 664.18/120 = 5.53 A.
The reactive power (Q) can be found using the formula Q = S × sin(arccos(0.72)), resulting in Q = 664.18 × sin(arccos(0.72)) = 536.65 VAR. In summary, the line current is 5.53 A, the reactive power is 536.65 VAR, and the apparent power is 664.18 VA.

Both bar elements for truss structures and beam elements for frame structures are line elements that are commonly used in structural engineering. While both types of elements serve the same general purpose of providing support and stability to a structure, there are some key differences between them.
One of the main differences between bar elements and beam elements is the way that they distribute loads. Bar elements, which are used in truss structures, distribute loads axially along their length. This means that they are designed to handle forces that act in a straight line, such as tension or compression. In contrast, beam elements, which are used in frame structures, distribute loads both axially and transversely. This means that they are designed to handle forces that act in a variety of directions, such as bending or shear.
In summary, the main differences between bar elements and beam elements are the way that they distribute loads, the way that they are supported, and their cross-sectional shape. While both types of elements are important for providing structural support, they are designed to handle different types of forces and are used in different types of structures.

technician a says that solder should be applied to the soldering iron tip while soldering. technician b says that the solder should be applied to the wire joint while soldering. who is correct?
Technician B is correct. Solder should be applied to the wire joint, not the soldering iron tip, while soldering.
The soldering iron tip should be used to heat the wire and the joint, and the solder should be applied to the joint to form a solid and reliable connection. Applying solder directly to the iron tip can cause it to build up and become less effective, leading to poor-quality joints. It is also important to use the right amount of solder and to ensure that the joint is clean and properly prepared before soldering to achieve a good connection.

10. inductive reactance, resistance, and impedance are all measured in ohms. what is the common characteristic that makes this possible?
The common characteristic that makes it possible for inductive reactance, resistance, and impedance to be measured in ohms is that they are all related to the flow of current in a circuit.
Resistance is a property of a material that opposes the flow of current through it, while inductive reactance is a property of an inductor that opposes the change in current flowing through it. Impedance is the total opposition to the flow of current in a circuit, which includes the effects of both resistance and reactance. Ohms is the unit of measurement used to quantify the amount of opposition to current flow in a circuit. Therefore, all three properties are expressed in ohms, making it easier to measure and analyze the flow of current in a circuit.
