Work Problem 1 except with the 10-in. dimension as 12 in. and the 18-in. radius as 15 in.

Problem 1

Determine the required outer diameter for the hollow shaft of Fig. 1 having an inner diameter 0.6 as great as the outer diameter. The shaft rotates and the loads are steady. You may use Syp = 60,000 psi, Se = 44,000 psi, Nfs = 2.0, and Kft = Kfb = 1.0.
