What is the difference between a compression spring and an extension spring?

Compression springs differ from extension springs in regards to how they work. While extension springs become longer under a load, compression springs become shorter. Compression springs are designed for use in applications where two components try to push towards each other.

### How are extension springs specified?

The dimensions of extension springs are normally given in their relaxed state. They may be specified in terms of outside diameter and inside diameter or wire diameter. The length of the body coils may be given in addition to the unloaded length inside the hooks as well as the maximum extended length inside the hooks.

How do I know what size extension spring I need for my garage door?

For extension springs, you’ll need to know the length of the spring, the weight that it’s intended to hold and the outside diameter. It is common that most residential garage doors are either seven or eight feet tall. Seven-foot doors usually use a 25-inch spring, and eight-foot doors use a 27-inch spring.

Torsion springs wound as concentric spirals from flat stock are sometimes called spring motors because of their use in mechanical watches, windup toys, etc. Drawbar, volute, and garter springs all rely on the mechanism of the coil spring to function.

What is the formula for extension?

Hooke’s Law states that the force needed to compress or extend a spring is directly proportional to the distance you stretch it. As an equation, Hooke’s Law can be represented as F = kx, where F is the force we apply, k is the spring constant, and x is the extension of the material (typically in meters).
