spiraalvedru
Spiraalvedru, also known as a helical spring or coil spring, is a mechanical device typically made from a metal rod or wire coiled into a spiral or helical shape. Its primary function is to store mechanical energy when deformed, and to exert a force or return to its original shape when the load is removed. The way a spiraalvedru behaves is determined by its material properties, the geometry of its coil, and the type of load applied.
Spiraalvedru can be classified into several types based on their configuration and the direction of force
These springs are ubiquitous in mechanical systems. They are found in everyday objects such as ballpoint pens,
