A circular disk is attached to the shaft at the location shown. What is the largest permissible angle of rotation f max of the disk if the allowable shear stress in the shaft is t allow ? (Assume that a . b . Also, use Eqs. 3-46a and b of Example 3-9 to obtain the reactive torques.) Solution 3.8-3 Shaft fixed at both ends
