Question
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)If the elongation of the bar, △l needs to be increased, suggest one suitable
parameter that should be change on the system. Consider the material of the
specimen is maintained with aluminium. Justify your answer in calculation.
