An unloaded aluminium bar is 1.5 m long and has a width and depth of 75 mm and 25 mm respectively, at room temperature. Determine the following when the bar is subjected to an axial tensile load of 180 kN.
(a) the tensile stress
(b) the tensile strain
(c) the lateral strain
(d) the change in width and depth of the cross-section
(e) the change in length of the bar
(f) If the temperature of the unloaded bar is now raised by 200 degrees Celsius, determine its new length.
Take Young's modulus, E = 65 GPa, Poisson's ratio, ? = 0.33, Coefficient of thermal expansion, ? = 23.4 x 10-6.
