A cantilever is subjected to a point moment of 50 kNm at point B and a point force of 100 kN at point C, as shown in Figure Q1. The beam has a constant flexural rigidity El throughout. 100 KN A 3m 50 kNm B * 3m C 6m Figure Q1 Based on the information provided, do the following: (a) Calculate all reactions of the structure. D (4 marks) (b) Plot the shear force diagram. Provide the key numerical values on the diagram, supported by your calculations. (6 marks) (c) Determine the rotation at point C using the method of superposition. (10 marks)
