Problem 15-12

The joists of a floor in a warehouse are to be selected using square timber beams made of oak. If each beam is to be designed to carry 90 lb/ft over a simply supported span of 25 ft, determine the dimension a of its square cross section to the nearest l in. The allowable bending stress is u allow = 4.5 ksi and the allowable shear stress is Tallow = 125 psi.
