What factors affect the rate of a coil spring?

You must remember, however, the only 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.
