L = 4 ft P q = 80 lb/ft t -L2 = 8 ft - + -L3 = 5 ft- h' = 3 in. 1 b=2in. Calculate the maximum tensile stress (in psi) for the beam shown in the figure with P = 683 lb and t=0.35 in. For this problem you need to do the following: 1) Calculate reactions 2) Draw the shear force and bending diagrams 3) Determine the maximum moment value and its location. 4) Calculate the centroid of the composite section 5) Calculate the Moment of Inertia of the cross section 6) Calculate maximum tensile stress
