A propped cantilever beam of length ? = 1 m, with an inner hinge at point B, carries a uniformly distributed load ?, as shown in Figure Q1 (a). The beam is made from a circular hollow section with an inner radius of ?? = 5 cm and a thickness of ? = 2 cm (refer to Figure Q1 (b)). The maximum allowable longitudinal stress of the beam is 150 N/mm2.
