Question
The solid steel rod (1) shown in the figure has an allowable
shear stress of 18 ksi. The brass tube (2) has an allowable
shear stress of 6 ksi. The outside diameter of the tube is D2
= 1.50 in., and its wall thickness is t2 = 0.125 in. The tube is
attached to a fixed plate at C, and both the rod and the
tube are welded to a rigid end plate at B. Calculate (a) the
largest torque T that can be applied at the upper end of the
steel rod if the allowable shear stress in tube (2) is not to be
exceeded. (b) the corresponding minimum diameter d1
required for steel rod (1).
