Stress
Strength of Materials The strength of any material can be defined in terms of Stress. Stress is the only way by which strength can be defined. And the Stress is defined as follows: Stress (σ) When a material is subjected to an external force, a resisting force induced within the component. The internal resistance force induced per unit area due to external force acting on a material or intensity of the forces distributed over a given section is called the stress at a point. Stress is donated by σ σ=P/A Where P is External Force applied ...
