he ends A and D of the two solid shafts AB and CD are fixed, while the ends B and C are connected to gears, as shown in the figure. Knowing that the maximum shear stress is 50 MPa in each axis, determine the maximum torque T that can be applied to gear B.

The 60-mm-diameter shaft is made of 6061-T6 aluminum. (Figure 1) Figure 1.20 m 1.20 m 1 of 1 Part A If the allowable shear stress is Tallow = 80 MPa, and the angle of twist of disk A relative to disk C is limited so that it does not exceed 0.060 rad, determine the maximum allowable torque T Express your answer to three significant figures and include the appropriate units.

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.
