A steel rod 2.0 m long has a cross-sectional area of `0.30cm^(2)`. The rod is now hung by one end from a support structure, and a 550 kg milling machine is hung from the strain, and the elongation of the rod.

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. If the elongations of the two rods are equal, the length of the steel rod (L) is { Y_(Brass) = 1.0 xx 10^(11) N//m^(2) and Y_(steel) = 2.0 xx 10^(11) N//m^(2)

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))
