Q1
As indicated in Figure 4, a tensile stress is to be applied along the long axis (z-axis) of an aluminium rectangular bar. The width of each edge of the bar is w0 = 2.3 mm, and the length is l0 = 12 mm. The bar's modulus of elasticity and Poisson's ratio are respectively 69 GPa and 0.35. It is believed that the material is isotropic. a)Calculate the width of the bar, w when the load of 7000 N is applied.

Consider a square-faced beam supporting a section of a building. a) Before installation, the length of the beam is found to be l0 = 15.02 m (figure a). After installation and construction, the length is remeasured and found to be l = 14.98 m (figure b). Determine Young's Modulus Y in N/m2 for the beam if it supports a mass m = 35000 kg and has a side length d = 1.9 m. b) Suppose that after the beam is installed it needs to be repaired. The weight it supports is removed and replaced with a new mass m2 (figure c). After the new mass is supported, the side length is remeasured and found to be larger with a difference of Δd. Assuming that this side length deformation is uniform and small, write an expression for determining Poisson's ratio v for this beam if its Young's modulus Y is known.
