When understanding springs, it’s important to know that there are different types of springs with different properties. One common type of spring is a compression spring, designed to compress when a force is applied and then return to its original shape when removed. But what about the opposite of a compression spring? Is there such a thing?

The answer is yes; there is an opposite to a compression spring, called a tension spring. While compression springs are designed to compress, they are designed to stretch when a force is applied to them and then return to their original shape when the force is removed.

What is a Tension Spring?

A tension or extension spring is a coiled spring designed to resist a pulling force. These springs store energy when stretched and release it when the force is released. They are commonly used in various applications, including automotive suspensions, garage doors, and trampolines.

Like compression springs, tension springs come in various sizes and materials. The size and material of the spring will depend on the specific application it is being used for.

How are Tension Springs Made?

Tension springs are typically made from round wire and are coiled tightly to create the desired tension. The amount of tension the spring can withstand is determined by the diameter of the wire, the number of coils, and the length of the spring.

The ends of the tension spring also play an important role in its functionality. The ends of the spring can be customized to fit specific applications. For example, a tension spring may have hooks or loops on the ends to allow it to be attached to other components.

Comparing Compression and Tension Springs

While compression and tension springs are opposite in terms of their functionality, there are some similarities between the two types of springs. For example, compression and tension springs are made from various materials, including steel, stainless steel, and titanium. Additionally, both types of springs can be manufactured in various sizes to fit specific applications.

However, the two types of springs also have some key differences. Compression springs are designed to resist a pushing force, while tension springs are designed to resist a pulling force. Additionally, compression springs are typically shorter and fatter than tension springs, which are longer and skinnier.

Conclusion

In summary, the opposite of a compression spring is a tension spring. While compression springs are designed to resist a pushing force, tension springs are designed to resist a pulling force. Tension springs are commonly used in various applications, including automotive suspensions, garage doors, and trampolines. Understanding the differences between compression and tension springs allows you to choose the right spring type for your application.
