These springs are commonly used for energy storage. These types of springs are made by joining rectangular metal strips to plane spirals. These are sometimes referred to as the elliptical spring, or cart spring, one of the oldest spring forms. A leaf spring forms a thin arc-shaped length of spring steel of a rectangular cross-section.
Vertical vibrations and impacts are buffered by variations in the spring deflection so that the potential energy is stored in spring as strain energy and then released slowly. So,
