A simply supported basswood beam is designed to carry a concentrated load P of 1100 lbf 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 lbm/ft3. Beam dimensions are: Web thickness tw = 1.5 in, flange thickness tf = 2 in., web width bw = 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)
