A rigid bar of weight W=3000 N hangs from three equally spaced wires, two of steel and one of aluminium as shown in the figure below. The diameter of the wires is 4 mm. Before they were loaded, all three wires had the same length. If the entire load is to be carried by the steel wires, then the 201 temperature increase AT (in°C) in all the three wires will be (Assume E= 210 GPa, αs = 6.5×10^-6/°C and αa = 12×10^-6/℃) A rigid bar of weight W=3000 N hangs from three equally spaced wires, two of steel and one of aluminium as shown in the figure below.
