(a) The overhanging beam of a structure is shown in Figure 3.1. The beam has a distributed load from point A to C and a concentrated load at point B. From the shear force, V diagram and the bending moment, M diagram of the beam, identify the distance, x from A when V=0 and M is at maximum. (12 marks) The normal stress due to bending and section modulus of the beam are 20 MPa and 50 mm respectively. The beam has a square cross section. Design the size of area of the cross section of the beam. i. ii. A 14 kN/m C 42 kN 2 m 1 m Figure 3.1 The overhanging beam. B (6 marks)
