Textbook Question
Chapter 5, Problem 64P
By modern standards, the shaft design of Prob. 5–63 is poor because it is so long. Suppose it is redesigned by halving the length dimensions. Using the same material and design factor as in Prob. 5–63, find the new shaft diameter.

A solid and a hollow shaft, connected by a coupling, transmit power. The outside diameters of the shafts are the same and the inside diameter of the hollow shaft is 75 % of its outside diameter. The solid shaft is three times as long as the hollow shaft. Take the modulus of rigidity for both shafts as 80 GPa. (a) If the angle of twist for the solid shaft is 1°, find the angle of twist for the hollow shaft. (b) If the maximum shear stress in the solid shaft is 30 MPa, find the maximum stress in the hollow shaft.
(5) A 76mm solid shaft is to be replaced with a hollow shaft of the same torsional strength. Determine the inside diameter and the percentage weight savings if the outside diameter of the hollow shaft is 100mm.
