A copper bar consists from three sections: sections 1 is of 25 mm diameter and 60 mm long, section 2 is of 15 mm diameter and 50 mm long and section 3 is 20 mm square and 40 mm long. The bar is subjected to an axial tensile load which induces a stress of 20 MN/m2 on the smallest cross section. Determine the total Increase in the length of the bar when the load is applied. For copper E=100 GN/m2.
