The tensile load on the bar mentioned varies from 4,000 lb to a minimum of 1,200 lb.  Rapid cycling for many million cycles is expected.  As the tensile load fluctuates between 4,000 lb and 1,200 lb, it creates fluctuating normal stresses.  Calculate the following stresses at the section through the hole.
