A simply supported 7 ft long solid wooden beam is designed to carry a concentrated load P = 600 lbf in the center. The distance between supports is 72 inches. The cross sectional area is 2” (inches) wide and 6” (inches) high. Determine the moment of mass of the beam (lbm), inertia (in4) and deflection (in). This wood has the following material properties: Modulus of elasticity = 2.5 x 106 psi and Density = 40 lbm/ft3.
