Time left 0:23: The driveshaft of an automobile is being designed to transmit 196 kW at 3177 rpm. Determine the minimum diameter (in mm) required for a solid steel shaft if the allowable shear stress in the shaft is not to exceed 27 MPa. Note: Do not include units in your answer Torsion: J=d 32 T 3=1 / J 0 = TL≤ GJ Jo = # (do"-di") Jot P = Tw 32 Answer: Next page

B) A simply supported shaft is shown in the following Figure. A constant magnitude distributed unit load p is applied as the shaft rotates. The shaft is also subject to a steady torque of Tmax 2000-N -m., find the diameter of shaft required to obtain a safety factor of 2.5 in fatigue loading if the shaft is steel of Sut 814 MPa and Sy 703 MPa. The dimensions are in cm, the distributed force in N/cm, and the torque is in N-m. No stress concentrations are present, the shaft is machined, the required reliability is 90%, and the shaft operates at room temperature Figure: 1= 20-cm: b = 18-cm ; a = 16 cm Applied distributed load p:= 1000 N em ; 区区

A solid shaft made from AISI 1040 cold-drawn steel is used to carry two V-belt, as shown in the Fig. 3. Pulley A receives power from a motor through a belt, with the belt tensions shown in Fig. 3. The power is transmitted through the shaft and delivered to the belt through pulley B. Assume the belt tension on the loose side is 10 percent of the tension on the tight side.
