A steel bar ABCD consists of three sections: AB is of 20mm diameter and 200 mm long, BC is 25 mm square and 400 mm long, and CD is of 12 mm diameter and 200mm long. The bar is subjected to an axial compressive load which induces a stress of 30 MN/m2 on the largest cross-section. Determine the total decrease in the length of the bar when the load is applied. For steel E = 210GN/m2.
