Figure Q1 shows a beam ABC that is roller and pin supported at A and B, respectively. The beam carries a uniformly distributed load, moments at A and a trapezoidal load (a) Calculate the reactions at the supports A and B. (b) (4 marks) Write the shear force, Vand bending moment, M expression for span AB. (c) (4 marks) Construct the shear force diagram and bending moment diagram of the beam, indicating all important values on each diagram.
