a) Determine the shape factor for a beam which has the cross-section given in Figure Q2(a). Assume that the material may be idealised as elastic-perfectly plastic and take the yield moment My = 6 kNm and the yield stress of the material oy = 320 MPa. 4.5 cm 9 cm 7 сm 1 cm Figure Q2 (a) b) A uniform I-section cantilever beam, built-in at one end and roller supported at the other, with a shape factor of 1.4, yield stress of 240 MPa and carrying a uniformly distributed load of 16 kN.m is shown in Figure Q2(b).Using a factor of safety against plastic collapse of 3, determine the required minimum elastic section modulus. 3 m 16 kN.m Figure Q2 (b)
