A brass rod of length 2 m and corss-sectinal area `2.0 cm^(2)` is attached to end to a steel rod of length L and corss-sectinal area `1.0 cm^(2)`. The compound rod is subjected to equal and opposite pulls of magnitude `5 xx 10^(4) N` at its ends.
If the elongations of the two rods are equal, then the length of the steel rod L is `(Y_("brass") = 1.0 xx 10^(11) Nm^(-2)` and `y_("steel") = 2.0 xx 10^(11) Nm^(-2))`

A brass of length 2 m and cross-sectional area 2.0 cm^(2) is attached end to end to a steel rod of length and cross-sectional area 1.0 cm^(2) . The compound rod is subjected to equal and oppsite pulls of magnitude 5 xx 10^(4) N at its ends.
