When the temperature of the bar is raised, and the bar is not free to expand, the bar tries to expand and exerts axial pressure on the wall. At the same time wall puts equal and opposite pressure on the bar, which will develop compressive stress in the bar.
If there is a drop in the temperature of the bar, the bar will try to contract, exerting a pull on the wall. At the same time, the wall offers an equal and opposite reaction exerting a pull on the bar, which will develop tensile stress in the bar.
Increase in temperature → Compressive stress
Decrease in temperature → Tensile stress

When a bar is subjected to an increase in temperature, and its deform...
Explanation:
When a bar is subjected to an increase in temperature, its length increases due to thermal expansion. If the deformation is prevented, the bar will be under stress. This stress is compressive stress as the bar is trying to expand but it is prevented due to external constraints.

The stress induced in the bar is not tensile stress as the bar is not being pulled apart, but rather it is being compressed from all sides. The stress is also not shear stress as there is no application of force parallel to the surface of the bar.

Therefore, the correct answer is option B, compressive stress.

Summary:
- When a bar is subjected to an increase in temperature, its length increases due to thermal expansion.
- If the deformation is prevented, the bar will be under stress.
- The stress induced in the bar is compressive stress.
- The stress is not tensile stress or shear stress.
