Please help me solve this question for part A and part B  label final answer with correct units for P = and D =
Learning Goal:
To determine the maximum possible power transmission for a circular shaft and the minimum
diameter required to avoid exceeding shear stress limits.
Part A- Transmitted power
A rotating shaft can be used to transmit mechanical power from one place to another. For example, a
shaft can be connected to a motor at one end and a pulley at the other. The shaft can then transmit
power from the motor to the pulley. When the machine is operating, the shaft will rotate at some
angular velocity w and will be subject to a torque T. The power transmitted by the shaft is P = Tw
A solid ciroular rod is used to transmit power from a motor to a machine. The diameter of the rod is D - 1.25 in and the machine operates at w- 100 rpm. If the allowable shear stress in the shaft is 10.6 ksi, what is the maximum power
transmissible to the machine?
The shaft's rotation can also be expressed as a frequency. , which represents the number of
revolutions of the shaft per unit time. The frequency and angular velocity are related by w = 2nf, so
the power can also be calculated using P- 2xfT.

In the SI system, the units of torque are newton-meters (N- m), and the units of power are watts (
1 W =1N- m/s). In the FPS system, the basic units of torque are foot-pounds (ft - Ib), and the
units of power are foot-pounds per second (ft - Ib/s). However, power is often expressed in
horsepower, where 1 hp = 550 ft - Ib/s.

Part B - Minimum diameter
A solid ciroular shaft is required to transmit P- 50 kW from a motor to a machine. The maximum alowable stress in the shaft is Ta - 75 MPa. If the machine runs at w- 17 rad/s, what is the minimum diameter for the shaft?
