1- For the beam shown in Figure P-1 draw shear and moment diagrams. If the maximum positive moment for the beam is 1,200 lb-ft and the maximum negative moment is 1,600 lb-ft determine the maximum tensile and compressive stresses in the beam. 2 - A composite beam is constructed of a wood beam 6 in. wide and 8 in. deep reinforced on the bottom by a 0.5 in. steel plate (Figure P-2). The modulus of elasticity for wood is Ew= 1,200 ksi and for the steel is E, = 30,000 ksi. Find the allowable moment Mallow for the beam if the allowable stress in the wood is ow= 1600 psi, and in the steel is o, = 15,000 psi.

Find the extreme fiber bending stress, fb, for a W-section used as a simple beam, with a uniformly distributed load, w, over the full length of the beam. W-section - W24x68 Span length = 35 ft Uniformly Distributed Load, w=2 k/ft Determine the Maximum Moment, MMAX, Find the Section Modulus of the beam, Sx, and calculate the Extreme Fiber Bending Stress, fb. Maximum Moment, MMax = Section Modulus of the Beam, Sx = Extreme Fiber Bending Stress, fb = Choose... Choose.... Choose... 0 •
