Question

(a) Determine the maximum compressive and tensile normal stresses in the A-36 structural steel beam shown and define their locations (location along the beam and on the cross section). (b) Determine the deflection of point B using the double integration method. The height of the cross section shown (in the y-direction) is 5 inches and width (in the z-direction) is 10 inches, and the average thickness throughout is 0.5 inches. (Use elastic properties for all calculations) 300 lb 20 lb/ft Rf 5.0 ft 3.0 ft
