Question

For the beam illustrated in the figure, find the locations and magnitudes of the maximum tensile bending stress due to Mand the maximum shear stress due to V. The parameters are a=5.5 in, b= 15 In, c= 0.75 in, h= 1.8 in, F1 = 2900 lbf, and 52 = 900 lbf. Filbi F2b1 Cin o ain A b in B A Cinc The moment of Inertia is The maximum tensile bending stress due to MIS psi. The maximum shear stress due to VIS psi.
