Two wires of diameter 0.25 cm, one made ...

Two wires of diameter `0.25 cm`, one made of steel and other made of brass, are loaded as shown in the figure. The unloaded length of the steel wire is `1.5 m` and that of brass is `1.0 m`. Young's modulus of steel is `2.0 xx 10^(11)`Pa and that of brass is `1.0 xx 10^(11)` Pa. Compute the ratio of elongations of steel and brass wires. `(/_\l_("steel"))/(/_\l_("brass"))=?`

Text Solution

Verified by Experts

The correct Answer is:
steel wire `1.49xx10^(-4)m,` brass wire `1.31xx10^(-4)m`
