A cantilever beam having a 4m span carries a uniformly distributed load throughout its length. The beam is A36 steel with yield strength Fy = 248 MPa. The beam is not restrained against lateral buckling. The beam is a W21 x 62 steel shape, whose relevant properties for this problem are: Rt = 0.053 meter tf = 0.016 m d = 0.533 meter S = 0.002077 m3 bf = 0.210 meter Determine the slenderness ratio, below which the beam is long with respect to lateral buckling. Determine the allowable flexural stress in the compressed flange. Determine the maximum value of the moment at the fixed support.
