A spring is an elastic device used to store and release mechanical potential energy when deformed by an applied force. These components are fundamental elements in mechanical engineering, utilized in diverse applications ranging from timekeeping mechanisms and suspension systems to scientific instruments. Their mechanical behavior is generally governed by principles of elasticity, and the relationship between applied force and displacement is crucial for design purposes. Various geometries, such as coiled, leaf, or torsion springs, are engineered from materials like steel or alloys to provide specific stiffness, resilience, and energy storage capacity required for precise functional performance within mechanical systems.
