strength of materials
A steel rod having a cross-sectional area of 300 mm’and a length of 150 m is suspended vertically from one end. It supports a tensile load of 20 kN at the lower end. If the unit mass of steel is 7850 kg/m3 and E = 200 x 103 MN/m, find the total elongation of the rod. Total this Question = 20 Marks Elongation due to its own weight: 75 m 150 m Si=PL/AE
