Question

Define longitudinal stress.

Answer 1

Longitudinal stress is the stress in a pipe wall, acting along the longitudinal axis of the pipe

Answer 2

Answer:

$longitudinal\ stress = \frac{Force}{Area}$

Explanation:

Generally the Stress is defined as the force applied on the body with respect to area of the cross - section of the body.

longitudinal stress is defined for closed circular pipe section.The stress acting along the wall of the pipe along the longitudinal direction is known as longitudinal stress.

$longitudinal\ stress = \frac{Force}{Area}$

It is represented by $\sigma$

S.I unit of longitudinal stress is N\m^2.
