Stretching and extension

Stretching and extension

Labelled setup for measuring spring extension with a clamp stand, vertical spring, ruler, pointer, and hanging masses, showing original length and stretched length

When a spring or wire is pulled, the applied load is a tensile force. In experiments the load usually comes from hanging masses, so the force is their weight.
