A prismatic bar with a circular cross section is loaded by tensile forces P = 65 kN (see figure). The bar has length L = 1.75 m and diameter d = 32 mm. It is made of aluminum alloy with modulus of elasticity E = 75 GPa and Poisson's ratio v = 1/3.
Find the increase in length of the bar and the percent decrease in its cross-sectional area.
