4. A beam is simply supported at A and C as shown in Figure 4. It is subjected to a
uniformly distributed load along BC and a concentrated moment at C. The origin of
the x and y axes is located at end A. (a) Draw the shear force diagram of the beam and indicate the shear forces at A, B, C and
(5 marks) (b) Derive the elastic curve of the beam in terms of x and flexural rigidity EI.
(10 marks) (c) Determine the deflection at D if E = 200 GPa.
