The spring stiffness of compression springs, extension springs and torsion springs, also known as the spring constant or spring moment rate, is a measure of the hardness of the metal spring. It indicates how much force is required to compress
Calculate spring rate for cylindrical springs
The spring rate, also called spring constant or spring hardness, depends on the spring material and the shape of the compression spring, extension spring or torsion spring. The formula for calculating the spring rate for cylindrical springs made of round
