w12x78 bridge crane runaway girder is on a simple span of 6 m. Assume that the crane wheel imparts a vertical load of 68 kN and a lateral load of 7 kN, applied at the top flange of the girder. A standard 0.4 kN/m rail will be used. Neglect shear and deflection. Properties of W21x78 d=300mm Ix=191.73×10^6mm4 W= 1.21 kN/m bf= 200mm ly = 35.07 x10^6mm4 Questions: Determine the Bending stress about the y - axis.

Beams

In structural engineering, a beam is a component made of a variety of materials (including steel alloys, and wood) that can resist loads applied laterally to the beam axis. Members, elements, rafters, shafts, and purlins are all terms used to describe beams.
