Two vertical wires are suspended at 450 mm apart. Their lower ends support a rigid horizontal bar that carries a load F. The left-hand wire is made of copper and has a diameter of 3 mm. The right-hand wire is made of steel and has a diameter of 2 mm. Calculate: (a) The position of F if the elongation in both wires is the same. (b) The load carried by each wire and the total elongation if F = 350 N and both wires are initially 3,5 m long. (Esteel = 200 GPa and Ecopper = 100 GPa).

Question
Two vertical wires are suspended at 450 mm apart. Their lower ends support a rigid horizontal bar that carries a load F. The left-hand wire is made of copper and has a diameter of 3 mm. The right-hand wire is made of steel and has a diameter of 2 mm.
Calculate:
(a) The position of F if the elongation in both wires is the same.
(b) The load carried by each wire and the total elongation if F = 350 N and both wires are initially 3,5 m long. (Esteel = 200 GPa and Ecopper = 100 GPa).
