while examining a valve spring from an engine that is being overhauled, technician a says that valve springs should be checked for free length and cracks. technician b says the spring should be checked for compressed spring pressure, nicks, and straightness. who is correct?

When a force is applied to a member and it is pointed at a joint, the member is in compression. When a force is directed away from a joint that the member is attached to, it is said to be in tension.

The pulling force transmitted axially by a string, rope, chain, or other similar object, or by each end of a rod, truss member, or other similar three-dimensional object, is referred to as tension in physics. Tension can also be described as the action-reaction pair of forces acting at each end of the aforementioned elements. Tension, the opposite of compression, is conceivable.

To measure tension as a transmitted force, an action-reaction pair of forces, or a restoring force, the International System of Units uses newtons (or pounds-force in Imperial units). At the point of attachment to the objects to which the string or rod is connected, the ends of a string or other object that transmits tension will exert forces in the direction of the string.

This is not the right conclusion, no. Temperature is one of many factors that might induce warping, but this is not the only one. Warping can also be influenced by other elements like humidity.

What is temperature ?

The physical concept of temperature indicates in numerical form how hot or cold something is. A thermometer is used to determine temperature. Thermometers are calibrated using a variety of temperature scales, which historically defined distinct reference points and calorimetry substances. As a result, maintaining the temperatures below the value calculated in part (e) is insufficient to ensure that the warping is not greater than 0.5 mm.

Laser beam machining and water jet cutting are the following processes would be appropriate for cutting a narrow slot, less than 0.015 inch wide, in a 3/8- inch thick sheet of fiber-reinforced plastic. Hence option d and f is correct.

Fiber reinforced plastic is defined as a polymer-based composite material that is strengthened by fiber support. Fiber-reinforced plastics (FRP) are composite materials that use glass or carbon fibers as reinforcement and polymer resins as a matrix.

Because laser cutting is a far less aggressive and abrasive process than water jet cutting, it is much more accurate. A laser can carefully and safely cut materials as thin as 0.006 inches, whereas water jet cutters can't handle cutting through surfaces smaller than 0.02 inches.

Thus, laser beam machining and water jet cutting are the following processes would be appropriate for cutting a narrow slot, less than 0.015 inch wide, in a 3/8- inch thick sheet of fiber-reinforced plastic. Hence option d and f is correct.

The thermal effects caused by putting a cylindrical fiber in an inviscid, perfect gas that an auditory wave travels through are described. The thermal conductivities and heat capacity of the fibers and the gas are limited. There are established expressions for the temperature distribution in the material and the gas.

Pressure oscillations in the gas, which are brought on by an acoustic wave's passage, are what cause the temperature distribution. It has been discovered that a dimensionless parameter's relative value can help determine whether the solution should be based on exact or approximative equations.

The pressure and temperature at the end of the heat addition process are 494.96 kPa and 1539 K respectively.

The force that is applied over a given area is measured as pressure. The units of pressure are frequently Pascals (Pa), newtons per square meter (N/m2 or kg/ms2), or pounds per square inch (Psi). There are additional units as well, such as the atmosphere (atm), torr, bar, and meters sea water (msw).

Either the capital P or the lowercase p is used to represent pressure in equations.

An equation's units are used to express pressure, which is typically expressed as follows:

P = F / A

where P is pressure, F is force, and A is area.

A) The phase margin is given by PM = -tan-1 (ωc/ζ) - 180

where ωc is the critical frequency and ζ is the damping ratio.

For a phase margin of 50°, we have

-tan-1 (ωc/ζ) = -130°

or

ωc/ζ = tan 130°

Now, the damping ratio is given by

ζ = -log(GM)/(√π2 + log2(GM))

where GM is the gain margin.

Substituting for ζ in the above equation, we get

ωc = tan 130° × -log(GM)/(√π2 + log2(GM))

Solving for GM, we get

GM = exp(-tan 130° × √π2 + log2(GM))

Now, we can calculate the gain K from the open-loop transfer function G(s) = K/ (s(s2 + s + 4))

K = GM × (s2 + s + 4)

Substituting for GM, we get

K = exp(-tan 130° × √π2 + log2(GM)) × (s2 + s + 4)

Hence, the value of the gain K such that the phase margin is 50° is given by

K = exp(-tan 130° × √π2 + log2(GM)) × (s2 + s + 4).

B) The gain margin for this case is given by

A Zener diode is a particular kind of diode made to consistently permit current to flow "backwards" (with inverted polarity) when a specific reverse voltage, called the Zener voltage, is reached.

A wide range of Zener voltages, some of which are even variable, are used in the manufacture of Zener diodes. The reverse conduction occurs in some Zener diodes with sharp,  highly dopped p - n junctions and low Zener voltages; in these cases, the Zener effect, named after Clarence Zener, is caused by electron quantum tunneling in the small gap between the p and n regions.

Avalanche breakdown also occurs during the operation of diodes with higher Zener voltages, which have a more gradual junction.
