What is a Spring?
- A spring is a flexible machine element that stores mechanical energy when subjected to tensile, compressive, bending, or torsional forces.
- Hooke‘s law states that the force applied on the spring is directly proportional to its deflection provided that it is within the elastic range.
- The most common form of spring is a helical spring which is made from a wire with a circular cross-section.
- The main objective of spring design is to determine the right combination of spring geometry and material that will achieve safe working stress at a practical cost.
- Spring materials are made from alloys such as steel, stainless steel, copper alloys, and nickel alloys.
