10 Q1 Cross section of a beam is shown in Figure Q1. The yield strength of the beam is 273 MPa. Take the dimensions of the cross section as a= 218 mm, b= 44 mm, c= 52 mm and d= 253 mm. Perform the following: (i). Estimate fully plastic moment of resistance; (ii). Evaluate the shape factor of the beam and write down what this value indicates; (iii). If you are permitted to change any one dimension in the given cross section (a or b or c or d in Figure Q1), identify with appropriate reasons, which dimension will affect the shape factor considerably. a Figure Q1 d
