Springs - Extension, DrawbarExtension springs and drawbar springs are both types of springs that are used in a variety of applications. Extension springs are typically used to provide a force that pulls two objects apart, while drawbar springs are used to provide a force that pushes two objects together. Both types of springs are commonly used in a wide range of applications, including automotive, aerospace, and industrial settings. Extension springs are typically made from wire that is formed into a coil, while drawbar springs are typically made from flat strips of metal that are bent into a specific shape. In both cases, the spring is designed to store and release energy in order to provide a force that can be used to move or hold objects in place.
