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

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

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

Stress is independent on temp but depends on load and pressure(force also).

As there is no obstruction and the bar is free, no stress will be induced.

Bar is free to expand and there is no obstruction so stress in bar is 0.

Stress depends upon load. There is no load so it cannot have any stress.

Bar is expend freely there is no resisting force so there is no stress.

Stress is not related to temperature. Stress is always force per area.

Stress = force/area.
Here force = 0,
Stress = 0,
Hence no stress.
Here force = 0,
Stress = 0,
Hence no stress.
