A solid 2.9-in.-diameter bronze [ G = 7100 ksi] shaft is 8-ft long. The allowable shear stress in the shaft is 10.2 ksi and the angle of twist must not exceed 0.034 rad. Determine the maximum horsepower P that this shaft can deliver: (a) when rotating at 182 rpm. (b) when rotating at 644 rpm.
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
