A 3mm thick hollow polystyrene cylinder (E = 3 GPa) and a rigid circular plate (only part of which is shown in Figure 2) are used to support a 6mm diameter steel rod AB (E = 200 GPa) of length 250mm against a rigid baseplate. If a 3.2 kN load P is applied at B, determine the following: (a) the elongation of rod AB. (b) the deflection at point B.
