What is the definition of stress?

In physics and engineering, stress is defined as the force per unit area applied to a material. It is a measure of the internal resistance of a material to deformation or strain when subjected to an external force. Stress is typically expressed in units of force per unit area, such as pascals (Pa) or pounds per square inch (psi).
Mathematically, stress (σ) is defined as:
Stress (σ) = Force (F) / Area (A)
Force (F) is the external force applied to the material, typically perpendicular to the area.
Area (A) is the cross-sectional area of the material perpendicular to the applied force.
Stress can be caused by various external forces, such as compression (pushing together), tension (pulling apart), shear (sliding or twisting), or bending (combination of compression and tension). Different materials have different abilities to withstand stress without permanent deformation or failure, and the study of stress and its effects on materials is an important aspect of materials science and engineering.
Stress is a fundamental concept in engineering and materials science, and it is used to analyze and design various structures and components, such as buildings, bridges, airplanes, and mechanical parts. Understanding stress and its effects on materials is critical in ensuring the safe and reliable operation of engineered systems.
