The equation describing this relationship describes the restoring force F that the spring exerts against the external force causing deformation. The restoring force is customarily negative to indicate it is the opposite direction of the force acting on the object, as it resists the deformatio...
Open Extension Spring Force Formula and Calculator About Extension Spring Design:Most extension springs are wound with an initial tension. This tension is the force that holds the spring coils wound together. The spring rate tends to be constant over the central 60 percent of the deflection range...

1) Find the spring constant of a spring if it requires a 9000 N force to pull it 30.0 cm from equilibrium. Answer:The formula can be rearranged to solve for the spring constant, k: In this question, a 9000 N force is pulling on a spring. That means that the spring pulls back with...
Spring Force Formula and Calculation: What is Spring Force? Spring force, also known as spring rate or spring constant, is the amount of force required to compress or extend a spring by a unit of distance. It is a measurement of the stiffness of a spring. The spring force is critical ...

Definition of compression spring: A compression spring is a mechanical device in the shape of a helix made from spring wire. It is used to store or release energy. It can also absorb shock or maintain a force between two surfaces.

Spring rate, also known as spring constant, is the constant amount of force it takes a compression or extension spring to travel a proportionate amount of distance. The unit of measurement of rate is, lbf/in, which stands for pounds of force per inch.
