asked in category: General Last Updated: 8th March, 2020# What factors affect the rate of a coil spring?

**factors that affect spring rate**are wire diameter, mean diameter, number of active

**coils**. How

**Spring Rates**Change Dynamically: Keep in mind that as a

**coil spring**compresses, the inactive (dead) end

**coils**gradually contact adjacent, active

**coils**.

Just so, what does coil spring rate mean?

**Spring rate** refers to the amount of weight that is needed to compress a **spring** one inch. If the **rate** of the **spring** is linear, its **rate** is not affected by the load that is put on the **spring**. For example, say you have a 200 lb. per inch **spring** - it will compress 1" when a 200 lb. load is placed onto the **spring**.

Also, what is spring rate formula? **Spring Rate Formula** **Rate** = Load ÷ Travel. k= L ÷ T. k = 15 ÷ 2. k = 7.5 lb/in.

Also, how does number of coils affect spring constant?

When the **number of coils** and **coil** diameter of a **spring** is large, that is, when the length of material increases, the **spring constant** becomes smaller. The same principle explains the **effect** with **spring constants** you described.

What is the formula for calculating spring rate?

To **calculate** the amount of **spring rate** you will need on order to meet your working loads, simply divide the load you will be applying on your **spring** by the distance you expect your **spring** to travel or compress under that load. The equivalent to that **formula** will be your compression **spring rate** as shown below.
