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.

Question
Transcribed Image Text: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.
