What is definition of stress in engineering?

Question

Accepted Answer

Stress in engineering refers to the internal force experienced by a material or structure due to external loads.

Stress is a measure of the intensity of the internal forces within a material or structure.
It is caused by external loads or forces acting on the material or structure.
Stress can be categorized into different types such as tensile, compressive, shear, and bending stress.
Tensile stress occurs when a material is being pulled apart, compressive stress occurs when a material is being squeezed, shear stress occurs when a material is being subjected to parallel forces in opposite directions, and bending stress occurs when a material is being bent.
For example, when a bridge is loaded with the weight of vehicles passing over it, the bridge experiences stress due to the external loads.
Understanding stress is crucial in engineering as it helps in designing structures and materials that can withstand the expected loads and prevent failure.

Accepted Answer

It is the internal resisting force acting per unit area of an arbitrary plane within the body.
