Question

The stress resulting in change in shape of the body due to the force applied is known as

Answer 1

The stress resulting in change in shape of the body due to the force applied is called longitudinal stress. Longitudinal stress is also known as two other types of stress. Tensile stress and compressive stress.

Answer 2

The stress resulting in change in shape of the body due to the force applied is known as longitudinal stress.

Definition of longitudinal stress:

"Longitudinal stress is defined as the stress produced when a linear object is subjected to internal pressure. The direction of the longitudinal stress in a linear object is parallel to the longitudinal axis of its centerline axis"

Formula:

Longitudinal stress = deforming force / area of cross-section

Longitudinal stress:

• Longitudinal stress is usually explained in terms of pipe or cylinder. If a cylinder is excerted with equal and opposite forces then the type of stress produced in the body of the cylinder is called as longitudinal stress.
• Since the force acts along the long axis of the body the resultant stress also acts along the long axis of the body. Therefore there is obvious change in the length of the body and a slight variation in the diameter.
• There are two types of longitudinal stresses - Tensile stress and compressive stress. Tensile stress tends to increase an object's length (extends) while compression stress tends to shorten the length of the object (compresses)
