Extracted text: Solve the problems below: A steel rod having a cross-sectional area of 300 mm and a length of 150 m is suspended vertically from one end. The rod supports a tensile load of 20 kN at its free end. Given that the mass density of steel is 7850 kg/m' andE = 200 GPa. find the total elongation of the rod. 1.
