Here's a breakdown:
* Stress is a measure of the internal forces that act within a material when it is subjected to an external force.
* Tensile stress occurs when the material is stretched, pulling the molecules apart.
* Compressive stress occurs when the material is compressed, pushing the molecules closer together.
Important Note:
* Stress is calculated by dividing the force applied by the cross-sectional area of the material.
* Strain is a measure of how much the material deforms under stress. It's calculated as the change in length divided by the original length.
