(See also Problem 6-34 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 bracket is subjected to a sinusoidal force-time function with Fmax = F and Fmin = 0, where F 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 fluctuating 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.‡
in this assignment, reflect deeply on a topic that matters to you. Each scenario represents a conflict in an organizational setting. In addition to applying ethical reasoning to your position, you must demonstrate how as a leader you would preserve the professional relationships in question and resolve the conflict.
