Spring ratio
22 Dec 2011, 8:50 AM
An extension or compression spring has units of force divided by distance, for example lbf/in or N/m. A spring is an elastic object used to store mechanical energy. When a spring is compressed or stretched, the force it exerts is proportional to its change in length. The rate or spring constant of a spring is the change in the force it exerts, divided by the change in deflection of the spring.
