Question
3.46 The electric motor exerts a torque of 800 N · m on the steel shaft
ABCD when it is rotating at a constant speed. Design specifications
require that the diameter of the shaft be uniform from A to D and
that the angle of twist between A and D not exceed 1.5°. Knowing
that Tmas s 60 MPa and G = 77 GPa, determine the minimum
diameter shaft that can be used.
