Key Concepts: Load: The tensile force exerted on an object, such as a spring or wire, which causes it to stretch or extend. Extension: The increase in an object’s length or deformation from its original state when subjected to a load. As the load applied to an object increases, the extension also increases. Initially, this … Read more
