Question

A simply supported basswood beam is designed to carry a concentrated load P of 1100 lb_f in the center. The distance L between supports is 70 inches. Basswood has the following properties: Modulus of Elasticity = 1.46 x 10⁶ psi; Density = 28 lb_m/ft³. Beam dimensions are: Web thickness t_w = 1.5 in, flange thickness t_f = 2 in., web width b_w = 4 in., flange height h = 6.75 in, total beam length = 110 in. What is the deflection of the beam (in inches) at the mid-point (center) of the span if designing to include a safety factor of 1.75? (Report result to 3 decimal places)
