A homogeneous block with a mass `m ` hangs on three vertical wires of equal length arranged symmetrically . Find the tensions of the wires if the middle wire is of steel and the other two are of copper . All the wires have the same cross - section . Consider the modulus of elasticity of steel to be double than that of copper .

A heavy plank of mass 100 kg hangs on three vertical wires of equal length arranged symmetrically (see figure). All the wires have the same cross - section. The middle wire is of steel and the other two are of copper . The modulus of elasticity of steel is assumed to be double that copper. Determine the tensions in the wire. (use g=9.8ms^-2 )
