a) Figure Q3(a) shows a rigid L-shaped beam 'ABCDE'. The beam is pinned at 'B' and simply supported at 'C'. The beam is subjected to a uniformly distributed load of 5 kN/m and two point loads of 2 kN and 7 kN at points A and E respectively. i) Sketch the free body diagram of the beam [3 marks] Determine the following: (ii) The reaction force at 'C'. [5 Marks] (iii) The resultant reaction in magnitude and direction of the pin joint at "B". [6 Marks] (iv) The magnitude of the shear force and bending moment at middle point of the step-beam (4m from A or D).
