A light rod of length 2 m is suspended from the ceiling horizontally by means of two vertical wires of equal length tied to its ends. One of the wire is made of steel and is cross section 10^-3 m^2 and the other is of brass of cross section 2 times 10^-3 m^2 . Young's modulus for steel is 2 times 10^11 N.m^-2 and for brass is 10^11 N.m^-2. Find out the position along the rod at which a weight may be hung to produce equals strains on both wires
