Basic Concepts of Compression Springs

Compression springs are mechanical devices that store energy when compressed. They are widely used in various mechanical systems to absorb shock, maintain force between contacting surfaces, and store energy. The principle behind compression springs involves the helical coil design, which allows the spring to compress along its axis. When a force is applied, the spring compresses, storing potential energy that is released when the force is removed, allowing the spring to return to its original shape ².
