For example, ashaft can be connected to a motor at one end and a• View Available Hint(s)pulley at the other. The shaft can then transmitpower from the motor to the pulley. When themachine is operating, the shaft will rotate at someangular velocity w and will be subject to a torqueT. The power transmitted by the shaft is P = Tw.HẢ?P= 38110.711HpThe shaft's rotation can also be expressed as afrequency, f, which represents the number ofrevolutions of the shaft per unit time. The frequencyand angular velocity are related by w = 2nf, sothe power can also be calculated usingP=2nƒT.SubmitPrevious AnswersX Incorrect; Try Again; 9 attempts remainingWhen designing a shaft, one consideration is limitsTcon shear stress. The torsion formula Tallow =Jrelates the allowable shear stress in a circular shaftPart B - Minimum diameterwith outer radius c to the torque T. The polarmoment of inertia is J= c for a solid shaft.2A solid circular shaft is required to transmit P = 43 kW from a motor to a machine. The maximum allowable stress in the shaft is Tallow = 75 MPa. If themachine runs at w = 16 rad/s. what is the minimum diameter for the shaft?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 basicunits of torque are foot-pounds (ft - lb), and theunits of power are foot-pounds per second (ft - lb/s). However, power is often expressed inhorsepower, where 1 hp = 550 ft - lb/s.Express your answer in cm to three significant figures.• View Available Hint(s)D= 5.67 cm

Question 1 You are working on a design team at a small orthopaedic firm. You have been asked to select a cobalt- chrome-molybdenum (CoCr) material that will not experience plastic deformation under a specific mechanical test, as follows... A tensile stress is applied along the long axis of a solid cylindrical rod that has a diameter of 10 mm. An applied load of some magnitude F produces a 7x10³ mm change in diameter (see figure below, original shape is blue, elongated shape is unshaded). Q1H: Provide a brief rationale based on calculations used to support your answer. That is, how would you explain the behavior of the "new alloy" material to your design team?
