When a bar is subjected to increase in temprature and its defromation is prevented , the stress induced in the bar is
Tensile
Compressive
Spear
None of the above
As we have learned
Longitudnal Stress (Compressive Stress) -
Decrease in length under a deforming force.
- wherein
As temprature increases wil cause increase in length hence to prevent this we must apply compressive stress
