Physics - Rotation Question with Solution | TestHub

A steel and a brass wire, each of length $50\mathrm{cm}$ and cross-sectional area $0.005{\mathrm{cm}}^2$ hang from a ceiling and are $15\mathrm{cm}$ apart. Lower ends of the wires are attached to a light horizontal bar. A suitable downward load is applied to the bar so that each of the wires extends in length by $0.1\mathrm{cm}$. At what distance from the steel wire the load must be applied? [Young's modulus of steel is $2\times 10^{12}$ dynes $/{\mathrm{cm}}^2$ and that of brass is $1\times 10^{12}$ dynes $/{\mathrm{cm}}^2]$
