![]() ![]() The spring force formula is expressed through the equation: F = – kx. ![]() Meaning, if the material returns to the dimension it had before the load or stress was applied, its deformation is reversible, non-permanent, and it ‘springs back.’ Elastic deformation occurs when the stress is removed. When a force is placed on the material, he observed, the material stretches or compresses in response to the force. The force of a spring is calculated using Hooke’s law, named for Robert Hooke, the 17th-century British physicist who developed the formula in 1660, as he studied springs and elasticity. Springs with larger spring constants will have smaller displacements than springs with lesser spring constants for the same mass added. In other words, it describes how stiff a spring is and how much it will stretch or compress. Spring constant is a characteristic of a spring which measures the ratio of the force affecting the spring to the displacement caused by it. It always acts so as to restore mass back toward its equilibrium position. When an object applies a force to a spring, then the spring applies an equal and opposite force to the object. Spring force is the force required or exerted to compress or stretch a spring upon any object that is attached to it. Its spring force is reactive, which generates mechanical energy – How much energy is represented by the spring constant. The spring’s wide use and application are due to its ability to store mechanical energy. From engines, appliances, tools, vehicles, and medical instruments-down to simple ball-point pens, the familiar metal coil has become an indispensable component in the modern world. They are a necessary component for a wide variety of mechanical devices. Springs are elastic mechanical objects which, after they are deformed, that is, after being stretched or compressed, they return to their original shape. ![]()
