1. A material has a modulus of rigidity of 100 GNm'2 and a Young's Modulus of 250 GNm-2. Calculate the expected value of poisons ratio for the material.
2. The simply supported beam shown in FIG 4 is 5m long with a Young's Modulus of 210 GNm'. The cross section of the beam is as shown in FIG 5.

(a) Draw the shear force diagram for the beam
(b) Determine the position and magnitude of the maximum bending moment.
(c) Plot a graph of deflection along the length of the beam (calculate the deflection at lm intervals).
