Length is proportional to temperature,
But, there is increase the temperature one stage to another stage so in this case affected to thermal stress.

If the free expansion is prevented then thermal stress will produce otherwise not.

Thermal stress depends on E, as young's modulus is not given stress is zero.

How stress is not related to temperature?

This Bar Is The Free to Expand. Hence no Resisting force is there so no stress Developed.

When no load on metal rod then stress and strain curve define is call plastic flow.

Said that it is free to expand, i.e. there is no load. As stress depends upon the load applied, no stress in the body.

Stress = load/area. It doesn't on the temperature.

Because bar is free to expand no any resisting force so no stress generate.

Because the body is free to expand so there is not any stress developed in the bar.
