Basic Concepts of Compression Springs

Compression springs are mechanical devices that store energy when compressed. They operate on the principle of Hooke’s Law, which states that the force exerted by a spring is directly proportional to its deflection. Key concepts include spring rate, which measures the stiffness of the spring, load, which is the force applied to the spring, and deflection, which is the distance the spring compresses under load. Common materials for compression springs include steel alloys, stainless steel, and music wire, chosen for their strength, durability, and resistance to fatigue ¹.
