A steel rod of length 1 m rests on a smooth horizontal base.

Question:

A steel rod of length $1 \mathrm{~m}$ rests on a smooth horizontal base. If it is heated from $0^{\circ} \mathrm{C}$ to $100^{\circ} \mathrm{C}$, what is the longitudinal strain developed?

Solution:

Since, there is no opposition in expansion of length, no stress develops and hence no longitudinal strain developed.
