A solid steel shaft will not twist through more than 3 degrees in a 6-m length when subjected to a torque of 12 KN*m. The modulus of rigidity of the steel shaft is 83 GPa. Determine; a) Diarneter of the shaft. (. b) Maximum shearing stress developed in the shaft.

! Required information The torques shown are exerted on pulleys A, B, and C, where T₁ = 3 kip-in. and 72 = 7.4 kip-in. Assume that both shafts are solid and the diameter of shafts AB and BC to be 1.3 in. and 1.8 in., respectively. T1 10.4 kip.in. 48 in. B 72 in. T2 C Determine the maximum shearing stress in shaft AB. The maximum shearing stress in shaft AB is ksi.

Required information The design of a machine element calls for a 40-mm-outer-diameter shaft to transmit 43 kW. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. 40 mm (a) (b) If the speed of rotation is 720 rpm, determine the maximum shearing stress in shaft a. The maximum shearing stress in shaft a is MPa.

A 0.75" diameter solid steel shaft is connected by the steel bolted coupling shown. The maximum allowable shear stress in the steel is 18 ksi (shaft and bolts). The coupling consists of steel bolts that are 1/8" diameter and the bolt holes are equally spaced and centered on a 4" diameter circle (2" radius from the center of the shaft to the center of a bolt hole). Determine a) The maximum torque that the shaft can carry Ans: /,491"* b) The number of bolts required for the torque in part a). Assume the bolts fail by shearing at the coupling interface and the shear stress is uniform across the bolt's cross sectional area.

The allowable shearing stress is 15 ksi in the 1.5-in.-diameter steel rod ABand 8 ksi in the 1.8-in.-diameter rod BC. Neglecting the effect of stress concentrations, determine the largest torque that can be applied at A

Under normal operating conditions, the electric motor exerts a torque of 2.4 kN·m on shaft AB. Each shaft is solid with diameter d 52 mm. In order to reduce the total mass of the assembly, a new design is being considered in which the diameter of shaft BC will be smaller. Determine the smallest diameter of shaft BC for which the maximum value of the shearing stress in the assembly will not be increased.        The smallest diameter of shaft BC is  mm.
