5. SCREW QUALITY CLASSIFICATION When a screw is tightened and the clamping force starts to build up, the material of the screw is stressed. After a short time when the thread settles the material will stretch in proportion to the force. In principle, this elongation will continue until the stress in the screw is equal to the tensile strength

Work is performed by applying a force over a distance. These simple machines create a greater output force than the input force; the ratio of these forces is the mechanical advantage of the machine. All six of the simple machines have been used for thousands of years, and the physics behind several of them were quantified by Archimedes .
