When a body subjected to temperature change & free to expand then there in no induced stresses. If the bar is restricted, then there is stress development.

There is no forces acting on the heated specimen which causes no stress on the bar.

It is not development stress on a bar because it is not external load act upon bar.

While applying tensile load no restrictions are there but still stress induces.

Stress is not depend on heat.

No stresses at all unless there is a opposing force.

Stress is not related to the increase in temperature.

Since it is given that condition is Free to expand so no stress is produce because stress is the resistance to the external force.

If the bar is free to expand or contract there will be no stress induced in the body.

Steel's melting point is very high so there is no need of worry about stress with out any load apply.
