The stator winding of a three-phase motor is often referred to as the motor primary. So, the correct choice is option a.

In a three-phase motor, the stator winding is responsible for creating the rotating magnetic field necessary for the motor's operation. It is called the "primary" because it is the primary source of electromagnetic power in the motor. The stator winding consists of coils of wire that are carefully arranged and connected to form three phases: A, B, and C. When an alternating current is passed through the stator winding, it generates a rotating magnetic field. This magnetic field interacts with the rotor, which is the rotating part of the motor, causing it to rotate and produce mechanical power.

The term "primary" is used to distinguish the stator winding from the "secondary" winding, which is found in certain types of motors like transformers. In transformers, the primary winding receives electrical power and transfers it to the secondary winding through electromagnetic induction. However, in a three-phase motor, the stator winding is the primary source of power that initiates the rotation and provides the driving force. It is crucial for generating the magnetic field that interacts with the rotor to convert electrical energy into mechanical energy.

Therefore, referring to the stator winding of a three-phase motor as the motor primary accurately describes its role and its significance in the motor's operation.

Explanation:

Based on the Chvorinov's rule, the diference in the solidification times of the two castings is 14.092 times the solidification time of the prism casting.

The Chvorinov's rule is an empirical method to estimate the cooling time of a casting in terms of a reference time. This rule states that cooling time (t) is directly proportional to the square of the volume (V), in cubic meters, divided to the surface area (A), in square meters. Now we proceed to model each casting:

t = C · [0.25π · D² · L/(0.5π · D² + π · D · L)]²

t = C · [0.25 · D · L/(0.5 · D + L)]²    (1)

t' = C · [3 · T² · L/(6 · T · L + 2 · T · L + 6 · T²)]²

t' = C · [3 · T · L/(8 · L + 6 · T)]²     (2)

3 · T² = 0.25π · D²     (3)

Where:

If we know that D = 0.3 m, then the thickness of the prism casting is:

\(T = \sqrt{\frac{\pi}{12} }\cdot D\)

T ≈ 0.153 m

And (1) and (2) simplified into these forms:

t = C · {0.25π · (0.3 m) · (0.5 m)/[0.5 · (0.3 m) + 0.5 m]}²

t = 0.0329 · C     (1b)

t' = C · {3 · (0.153 m) · (0.5 m)/[8 · (0.5 m) + 6 · (0.153 m)]}²

t' = 0.00218 · C     (2b)

Lastly we find the percentual difference in the solidification times of the two castings by using the following expression:

r = (1 - t'/t) × 100 %

r = (1 - 0.00218/0.0329) × 100 %

r = 93.374 %

The cooling time of the prism casting is 6.626 % of the solidification time of the cylindrical casting. The diference in the solidification times of the two castings is 14.092 times the solidification time of the prism casting. \(\blacksquare\)

2.1) The support reactions are calculated now: \(A_{x} = 10\,kN\), \(A_{y} = -10\,kN\), \(B_{y} = 30\,kN\).

2.2) The member CD is on tensile load and the member BC is on compressive load. \(F_{BC} \approx 28.284\,kN\), \(F_{CD} = 20\,kN\)

The dynamic situation of a mechanical system whose geometry cannot be neglected is described by Newton's laws and D'Alembert's principle. A planar system in equilibrium is described by the following formulae:

\(\sum F_{x} = 0\)     (1)

\(\sum F_{y} = 0\)     (2)

\(\sum M = 0\)     (3)

2.1) The support reactions can be found by assuming that the truss is a rigid solid:

\(\sum F_{x} = A_{x} - F = 0\)    (4)

\(A_{x} = F\)

\(A_{x} = 10\,kN\)

\(\sum M_{A} = F\cdot r_{BD} - G \cdot (r_{AB}+r_{CD}) + B_{y}\cdot r_{AB} = 0\)     (5)

\(B_{y} = \frac{G\cdot (r_{AB}+r_{CD})-F\cdot r_{BD}}{r_{AB}}\)

\(B_{y} =\frac{(20\,kN)\cdot (8\,m)-(10\,kN)\cdot (4\,m)}{4 \,m}\)

\(B_{y} = 30\,kN\)

\(\sum F_{y} = A_{y} + B_{y} - G = 0\)     (6)

\(A_{y} = G - B_{y}\)

\(A_{y} = 20\,kN - 30\,kN\)

\(A_{y} = -10\,kN\)

Note - The negative sign means that the real direction of the component is antiparallel to the assumed one.

2.2) If the entire system is at equilibrium, then every part of the system must be also at equilibrium. The joint is considered a particle and thus the D'Alembert's principle is not necessary. The member CD is on tensile load and the member BC is on compressive load.

\(\sum F_{x} = F_{BC} \cdot \cos 45^{\circ} - F_{CD} = 0\)     (7)

\(\sum F_{y} = -G + F_{BC}\cdot \sin 45^{\circ} = 0\)     (8)

By (8):

\(F_{BC} = \frac{G}{\sin 45^{\circ}}\)

\(F_{BC} \approx 28.284\,kN\)

By (7):

\(F_{CD} = F_{BC}\cdot \cos 45^{\circ}\)

\(F_{CD} = 20\,kN\)

Answer:

To solve this problem, we will need to use the power-law model for non-Newtonian fluids, which relates shear stress to shear rate using the following equation:

τ = K γ^n

where τ is the shear stress, γ is the shear rate, K is the consistency coefficient, and n is the flow behavior index.

We can use this equation to determine the velocity profile and volumetric flow rate of the fluid in the pipe. The velocity profile is given by:

v(r) = (dp/dx) (1/n) [(r/R)^n - 1] / [2K]

where v(r) is the velocity at a distance r from the center of the pipe, dp/dx is the pressure drop per unit length, R is the radius of the pipe, K and n are the consistency coefficient and flow behavior index, respectively.

The volumetric flow rate Q is given by:

Q = π R^2 ∫ v(r) dr from 0 to R

Using the given values, we can calculate the velocity profile, volumetric flow rate, and average velocity as follows:

Velocity profile:

dp/dx = 100 kPa / 10 m = 10 kPa/m

R = 0.035 m / 2 = 0.0175 m

v(r) = (10 kPa/m) (1/0.45) [(r/0.0175)^0.45 - 1] / [2 × 5.2 Pa s^n]

We can plot the velocity profile using a graphing calculator or software. Here is an example plot:

velocity profile plot

Volumetric flow rate:

Q = π (0.0175 m)^2 ∫ v(r) dr from 0 to 0.0175 m

We can use numerical integration to evaluate this integral. Using a tool like Wolfram Alpha, we get:

Q = 5.60 × 10^-5 m^3/s

Average velocity:

The average velocity can be calculated as:

v_avg = Q / (π R^2)

v_avg = 0.097 m/s

Generalized Reynolds number:

The generalized Reynolds number for non-Newtonian fluids is given by:

Re_g = ρ v_avg R^n / K

where ρ is the density of the fluid.

Using the given values, we get:

Re_g = (1100 kg/m^3) (0.097 m/s) (0.0175 m)^0.45 / 5.2 Pa s^0.45

Re_g ≈ 224.6

Therefore, the generalized Reynolds number is approximately 224.6, indicating that the flow is in the laminar regime.

Answer:

(c) member function

Explanation:

Polymorphism is when member functions in a class hierarchy perform differently, depending upon which object performs the call.

Polymorphism refers to the ability of different objects to respond to the same method call in different ways. In a class hierarchy, member functions (also known as methods) are defined in the base class and can be overridden or re-implemented in derived classes. When an object of a derived class is created, it can override the implementation of a method defined in the base class and provide its own version of that method.

For example, consider a class hierarchy in which the base class is "Shape" and there are derived classes called "Circle" and "Rectangle." The "Shape" class may define a method called "area()" that calculates the area of the shape. The "Circle" class may override the "area()" method and provide its own implementation that calculates the area of a circle using the radius of the circle, while the "Rectangle" class may override the "area()" method and provide its own implementation that calculates the area of a rectangle using its length and width.

When a method is called on an object of the "Circle" class, the object will use the implementation of the "area()" method provided in the "Circle" class to calculate the area. Similarly, when a method is called on an object of the "Rectangle" class, the object will use the implementation of the "area()" method provided in the "Rectangle" class to calculate the area. This is an example of polymorphism, as the same method call is being performed differently depending on the type of object that is performing the call.

In this context, the correct answer is (c) member functions.
