There are several types of springs, each designed for specific applications based on their unique characteristics and functionalities:

Compression Springs
Features: These springs are designed to absorb and store energy when subjected to a compressive force. They provide resistance to being compressed and return to their original shape when the force is removed.
Applications: Automotive, industrial machinery, electronics, and more.

Extension Springs
Features: Extension springs are designed to resist stretching and store energy when pulled apart. They exert a pulling force when extended and return to their original length when the force is released.
Applications: Garage doors, trampolines, door hinges, and various industrial equipment.

Torsion Springs
Features: Torsion springs are designed to withstand rotational or twisting motion. They store mechanical energy when twisted and exert rotational force.
Applications: Garage doors, clipboards, clothespins, and various machinery.

Coil Springs
Features: Coil springs refer to springs formed by winding wire into a cylindrical shape. They can include compression, extension, or torsion springs based on their design and function.
