Calculating Consistent Force Calculator

Understanding the dynamics to determine the amount of consistent force required to compress a coil compression spring to a specific loaded height is a crucial aspect of spring design. This calculation is achieved by multiplying the force by the distance that the coil compression spring is expected to travel. The unit of measurement for consistent force is pounds of force per inch, denoted as lbf/in. Leverage the convenience of the compression spring calculator provided above to simplify these essential coil compression spring calculations. Simply input your spring's dimensions into this new tool to reveal the spring's rate or consistent force but also offers valuable insights into the maximum load that can be safely applied to the spring, as well as the maximum travel based on all the springs dynamics. Sometimes, springs can safely travel down to their solid height. Sometimes they can’t, why? Because certain factors, such as key physical spring dimensions like number of coils and spring index affect the elasticity of the spring which will impact the springs capability of full travel down to solid height or coil bind height. Illustration: Let's consider an example. You have a spring with a length of 12 inches that needs to compress to a loaded height of 7 inches under a 5-pound force.

 

Example:

A spring of 12” (inches) has to travel 5” to a loaded height of 7” with a load or force of 5 lb. (pounds).

k = F ÷ x
k = 5 ÷ 5
k = 1 lbf/in (pounds of force per inch)

F = Force
x = Distance Traveled
k = Constant or Rate
 

Here: F = Force x = Distance Traveled k = Rate or Consistent Force
