Question
2. A simply supported beam with a span of 6.50 meters is subjected to a counter clockwise moment at the left support and a clockwise moment at the right support equal to 50% of the moment at the left, both acting in the plane of the minor axis of the beam. The beam is restrained againat lateral buckling. The beam is A36 steel with yield strength of 248 MPa. The beam is a W 21 x 62 steel shape whose relevant properties as follows:/ R = 0.053 m d = 0.533 m a. Determine the alenderness ratio, above which the beam ia long with respect to lateral buckling. b. Determine the allowable flexural stress in the compressive flange. c. Determine the maximum value of the moment at the left support. br= 0.210 m t = 0.016 m S= 0.002077 m
