# A steel bar (E= 210 GPa, v= 0.30) ABCD consists of three sections: AB is of 30mm diameter and 300mm long, BC has a square cross section 35mm on a side and is 400mm long and CD has a diameter of 15mm and is 100mm long. The sections have a common axis along the length of the bar. the bar is subjected to an axial compressive load which induces a stress of 40 MPa on the region of the largest cross section. Determine the change in length of the bar.
