A horizontal bar is supported by two suspended vertical 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 3 mm in diameter. The length of both wires is 4 m initially. Neglect the weight of the bar and take ES = 210 GPa and EC = 120 GPa. 24. Find the position of the weight on

Question

A horizontal bar is supported by two suspended vertical 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 3 mm in diameter. The length of both wires is 4 m initially. Neglect the weight of the bar and take ES = 210 GPa and EC = 120 GPa. 24.

Find the position of the weight on the bar relative to the copper wire so that both the wires extend by the same amount.

Calculate the stress in the steel wire if W = 1 kN.

Calculate the stress in the copper wire if W = 1 kN.
