What is stress, Engineering Stress Strain Curve vs True Stress Strain curve, Moment vs Torque.

Question

Accepted Answer

Stress is the force per unit area. Engineering stress-strain curve is based on original dimensions while true stress-strain curve is based on instantaneous dimensions. Moment is the force that causes rotation while torque is the measure of the force's ability to cause rotation.

Stress is the force per unit area that a material experiences when subjected to an external force.
Engineering stress-strain curve is based on the original dimensions of the material while true stress-strain curve is based on the instantaneous dimensions of the material.
Moment is the force that causes rotation around a point while torque is the measure of the force's ability to cause rotation.
Examples of stress include tension, compression, and shear stress.
Examples of moment include bending and twisting moments.
Examples of torque include the force required to turn a bolt or a screw.
