## Find the forces acting on each of the 4 cap screws due to this fully reversed loading and choose a suitable cap screw diameter, length, and preload that will give a minimum safety factor of 1.5 for any possible mode of failure for N = 5E8 cycles.‡

(See also Problem 6-33 on p. 412.) The bracket in Figure P15-2 is fastened to the wall by 4 cap screws equispaced on a 10-cm-dia bolt circle and arranged as shown. The wall is the same material as the bracket. The bracket is subjected to a sinusoidal force-time function with Fmax and Fmin = –F, where and the beam’s other data are given in the row(s) assigned from Table P15-1. Find the forces acting on each of the 4 cap screws due to this fully reversed loading and choose a suitable cap screw diameter, length, and preload that will give a minimum safety factor of 1.5 for any possible mode of failure for = 5E8 cycles.‡
