Question

The stress which is set up in the body due to an increase in its dimensions is called_.

Answer 1

When the material is under tension, it is known as tensile. The forces that are acting along the axis of force are responsible for the stretching of the material. The internal resistive force per unit area of the material resulting in the stretch of the material is known as tensile stress.

$\sigma =\frac{P}{A}$

where,

$\sigma$ is Tensile stress

$P$ is Internal resistive force

$A$ is Cross-sectional area
