Engineering Reference
Learn the theory behind the Spring Force Calculator
Hooke's Law, formulated by Robert Hooke in 1678, states that the force required to extend or compress a spring is proportional to its displacement: F = kx, where k is the spring constant (stiffness) in N/m and x is the displacement from the equilibrium position. This linear relationship holds within the elastic limit of the spring material.
The elastic potential energy stored in a deformed spring is PE = ½kx², which is fundamental to understanding spring-mass systems, vibration isolation, and energy storage. The natural frequency of a spring-mass system is f_n = (1/2π)√(k/m), critical for avoiding resonance in mechanical design.
