|All About Coil Springs|
Robert Hooke (1635-1703) observed that when an elastic body is subjected to stress its dimension or shape changes in proportion to the applied stress over a range of stresses. In 1678, Robert Hooke, on the basis of his experiments with springs, stretching wires, and coils, stated a rule between extension and force.This led to Hooke's law which states that strain, the relative change in dimension, is proportional to stress. If the stress applied to a body goes beyond a certain value known as the elastic limit, the body does not return to its original state once the stress is removed. Hooke's law applies only in the region below the elastic limit. Algebraically, this rule has the following form: F = kx Hooke's Law explained the science behind coil springs.
