Answers
correct answer is (i). Angles of departure/arrival: The angles of departure/arrival can be calculated using the formula:
θ = (2n + 1)π / N
where θ is the angle, n is the index, and N is the total number of branches. For the given roots, we have:
θ1 = (2 * 0 + 1)π / 4 = π / 4
θ2 = (2 * 1 + 1)π / 4 = 3π / 4
θ3 = (2 * 2 + 1)π / 4 = 5π / 4
θ4 = (2 * 3 + 1)π / 4 = 7π / 4
ii. Asymptotes: The number of asymptotes in the root locus plot is given by the formula:
N = P - Z
where N is the number of asymptotes, P is the number of poles of the open-loop transfer function, and Z is the number of zeros of the open-loop transfer function. From the given transfer function, we have P = 3 and Z = 0. Therefore, N = 3.
The asymptotes are given by the formula:
σa = (Σpoles - Σzeros) / N
where σa is the real part of the asymptote. For the given transfer function, we have:
σa = (1 + 4 + (-5)) / 3 = 0
Therefore, the asymptotes are parallel to the imaginary axis.
iii. Sketching the Root Locus: To sketch the root locus, we plot the poles and zeros on the complex plane. The root locus branches start from the poles and move towards the zeros or to infinity. We connect the branches to form the root locus plot. The angles of departure/arrival and asymptotes help us determine the direction and behavior of the branches.
iv. Range of K for underdamped response: For an underdamped response, the root locus branches should lie on the left-hand side of the complex plane. To find the range of K for an underdamped response, we examine the real-axis segment between adjacent poles. If this segment lies on the left-hand side of an odd number of poles and zeros, then the system will exhibit underdamped response. In this case, the segment lies between the poles at -1 and 4.
i. The angles of departure/arrival are π/4, 3π/4, 5π/4, and 7π/4.
ii. The asymptotes are parallel to the imaginary axis.
iii. The sketch of the root locus plot should be drawn based on the given information.
iv. The range of K for under-damped response is determined by examining the real-axis segment between adjacent poles. In this case, the segment lies between the poles at -1 and 4.

2) What is packing the mold and why is it important in obtaining good injection molded parts?
3) How does high crystallinity in a resin affect the way the resin is injection molded, including any post-molding operations that might be done?
4) Why is it important to have the sections of the molded part as uniform in thickness as possible?
5) Assume that you are assigned to determine the minimum clamping force for a part to be molded out of polystyrene. The part cross-sectional area is 10 x 14 inches. What is the clamping force required if as a general rule, 2.5 tons of force are needed for each square inch of cross-sectional area?
6) Why is low specific heat capacity desired in a mold cavity material for some applications and a high specific heat capacity desired in others?
7) What feature in a mold will allow a hollow, cylindrical part to be made? Why are injection molding machines not as effective for mixing additives or other resins as are traditional extrusion machines?
8) What is a vent in the mold, what problems are prevented by the presence of a vent, and what parameters control its size?
Answers
1) The two measures used in rating the size of an injection molding machine are the clamping force and the shot capacity. The clamping force refers to the force exerted by the machine to keep the mold closed during the injection process.
2) Packing the mold involves applying additional pressure to the resin after the injection phase. This is done to ensure that the mold cavity is completely filled and that the plastic material is properly packed within the mold. Good packing is important because it helps to eliminate voids, reduce shrinkage, and improve the overall strength and quality of the injection molded parts.
3) High crystallinity in a resin affects the injection molding process and post-molding operations. Resins with high crystallinity tend to have slower melt flow rates, requiring higher processing temperatures and longer cooling times.
4) It is important to have uniform thickness in the sections of a molded part to ensure consistent cooling and minimize the risk of defects.
5) To determine the clamping force required, we multiply the part cross-sectional area (10 x 14 inches) by the general rule of 2.5 tons of force per square inch.
6) Low specific heat capacity is desired in a mold cavity material for some applications because it allows for faster cooling and shorter cycle times.
7) A feature in a mold that allows a hollow, cylindrical part to be made is called a core. The core creates the internal cavity of the part while the mold cavity forms the external shape.
8) A vent in the mold is a narrow gap or channel that allows for the escape of air, gases, or excess material during the injection molding process. It helps to prevent issues such as air trapping, burn marks, and incomplete filling of the mold cavity.

Define:

b) Saturated steam
c) Overheated steam
d) Compressed liquid
e) Critical point
Answers
Saturated (dry) steam results when water is heated to the boiling point (sensible heating) and then vaporized with additional heat (latent heating). If this steam is then further heated above the saturation point, it becomes superheated steam (sensible heating).
DescriptionSuperheated steam is steam at a temperature higher than its vaporization point at the absolute pressure where the temperature is measured. Superheated steam can therefore cool by some amount, resulting in a lowering of its temperature without changing state from a gas, to a mixture of saturated vapor and liquid.
Compressed liquid (subcooled liquid): A substance that it is not about to vaporize. • Saturated liquid: A liquid that is about to vaporize. At 1 atm and 20°C, water exists in the liquid phase (compressed liquid). At 1 atm pressure and 100°C, water exists as a liquid that is ready to vaporize (saturated liquid).
A critical point occurs when the derivative is 0 or undefined. If our equation is f(x)=mx+b, we get f'(x)=m. So if the function is constant (m=0) we get infinitely many critical points. Otherwise, we have no critical points.

Answers
In geometry, the area enclosed by a circle of radius r is πr2. Here, the Greek letter π represents a constant approximately equal to 3.1 159, which is the ratio of the circumference of any circle to its diameter.
What is 2πr of a circle?Circumference (or) of a circle = 2πR,Pi (π) is a special mathematical ; it is the ratio of the circumference to the diameter of any circle. Because it is mathematically defined as the ratio of the circumference to the diameter of a circle, it is used in every circular equation. a circle also has no sides, so no other equations can be used.
What is the area of a circle Πr²?As we know, the area of a circle is pi times the square of its radius, i.e. π x r2. To find the area of a circle, we need to know the radius or diameter of the circle. For example, if the radius of a circle is 7 cm, its area is: Area of a circle with a radius of 7 cm = πr2 = π(7)2 = 22/7 x 7 x 7 = 22 x 7 = 15.

Answers
In an operating air conditioning system, the refrigerant undergoes two physical states - gas and liquid.
How is this so?The refrigerant starts as a low-pressure gas in the evaporator coil, where it absorbs heat from the surrounding air and evaporates, transforming into a high-pressure, high-temperature gas.
It then travels to the condenser coil, where it releases heat to the outside air and condenses back into a liquid state.
This cycle allows for the efficient transfer of heat and cooling within the air conditioning system.

Which defect would you expect to exist in a higher concentration in ceramics?.
Answers
There are several defects that can exist in ceramics, such as point defects, line defects, and planar defects. However, one defect that is particularly common in ceramics is known as a grain boundary.
Grain boundaries are planar defects that occur where two crystals meet. In ceramics, these boundaries can be caused by variations in crystal orientation, impurities, or changes in temperature during the manufacturing process.
Due to their high surface area, grain boundaries can significantly affect the properties of ceramics. They can act as sites for chemical reactions, alter the mechanical properties of the material, and even impact its electrical conductivity. In general, the concentration of grain boundaries in ceramics tends to increase as the grain size decreases. This is because smaller grains have a higher surface area to volume ratio, which means that there are more opportunities for grain boundaries to form.
