A stell rod of length 1 m rests on a smooth horizontal base. If it is heates from `0^C` to `100^C`, what is the longitudional strain developed?

Text Solution

Verified by Experts

Given, `Delta T = 100^@C`
` A longitudinal strain develops if and only
if there is an opposition to the expansion.
Since there is no opposition in this case
the longitudinal strain= zero.
