An iron bar of length `L`. Cross section `A` and Young's modulus `Y` is heated from `o^(o)C` to `100^(0)C`. If this bar is held so that it is not permitted to bend and to expand, the force `F` that is develop, is proportional to

An iron bar of length I and having a cross-section area A is heated from 0^(@) to 100^(@)C . If this bar is so held that it is not permitted to expand or bend, the force that is developed, is

An iron of length l and having cross-section A is heated form 0^(@)C to 100^(@) C. IF his bar is held so that it is not permitted to expand or bend, the gigantic force that is developed is

An iron bar of length and having a cross section A is heated from 0 to 100^@C . If this bar is so held that it is not permitted to expand or bend, the force that is developed, is

A rod of length l and area of cross-section A is heated from 0^(@)C to 100^(@)C . The rod is so placed that it is not allowed to increase in length, then the force developed is proportional to

An iron bar of length L and area of cross section A is heated from 10^circ C to 90^circ C , The bar is so held between supports that it is neither allowed to extend nor allowed to bend If the stress developed in the bar be S, then
