a) A beam with a solid homogeneous rectangular section is simply supported at A and B. A concentrated load F = 150 kilonewtons (kN) acts at point C where distance L1 (A to C) = 2.50 metres (m) and distance L2 (C to B) = 1.65 metres (m). The dimensions of the rectangular section of the beam are breadth, b = 35 mm and depth d = 125 mm.
