Question: The beam shown in the accompanying figure is a wide-flange W 18 x 35, with a cross-sectional area of 10.3 in2 and a depth of 17.7 in. The second moment of area is 510 in6.The beam is subjected to a uniformly distributed load of 2000 lb/ft. The modulus of elasticity of the beam is E = 29 x 106 lb/in2. Using manual calculations, determine the vertical displacement at node 3 and the rotations at nodes 2 and 3.Also, compute the reaction forces at nodes 1 and 2 and reaction moment at node 1.
