A horizontal bar supported by two suspended verti- cal wires 240 mm apart fixed to a rigid support. A load W is attached to the bar. The left-hand side wire is of copper with a diameter of 5 mm and the right-hand side wire is of steel of 3-mm diameter. The length of both the wires is 4 m initially. Find the position of the weight on the bar relative to the copper wire so that both the wires extend by the Example 1.21 4 m same amount. 240 mm Also, calculate the load, stresses and the elongation of each wire if W = I kN. Neglect the weight of the bar and take E, = 210 GPa and E, 120 GPa. %3D %3D Solution Given A horizontal bar system as shown in Fig. 1.35. Both wires extend by the same amount. COPPER STEEL
