Three solid cylindrical rods are welded together to form the compound axial member shown in the figure. The compound axial member is attached to a fixed support at A. Each rod has an elastic modulus of E = 47 GPa. Use the following values for the rod lengths and areas: L = 1530 mm, L2 = 1720 mm, L3 = 1210 mm, A1 = 250 mm^2, A2 = 155 mm, and Az = 65 mm. What magnitude of external load P is needed to displace end Da distance of up= 80 mm to the right? Find the relationship between &1, the elongation of rod (1), and the internal tensile force, F1, in rod (1). Assume &1 is a positive value in units of mm and F1 is a positive value in units of kN. So, the answer you enter for the ratio (&1/F1) must be in units of (mm/kN). Similar to the previous step, find the relationship between 82, the elongation of rod (2), and the internal tensile force, F2, in rod(2). Assume &z is a positive value in units of mm and F2 is a positive value in units of kN. So, the answer you enter for the ratio (&z/F2) must be in units of (mm/kN). Similar to the previous step, find the relationship between 83, the elongation of rod (2), and the internal tensile force, F3, in rod(2). Assume &z is a positive value in units of mm and F3 is a positive value in units of kN. So, the answer you enter for the ratio (&z/F3) must be in units of (mm/kN). Choose the correct relationship between the internal tensile forces in rods (1). (2), and (3), denoted F1,F2, and F3, respectively,and the applied load, P.
