A rectangular-sectioned beam of 75 mm x 50 mrn cross-section is used as a simply supported beamand carries a uniformly distributed load of 500 N/m over a span of 3 m. The beam is supported in such a way thatits long edges are inclined at 20″ to the vertical. Determine:(a) the maximum stress set up in the cross-section:(b) the vertical deflection at mid-span.E = 208 GNlm’ ,
