In general you can find the slope. Hooke s law spring constant calculator.

Measure the slope of the force extension graph.

Calculate the spring constant. Choose a value of spring constant for example 80 n m. F k x 80 0 15 12 n. Looking only at the magnitudes and therefore omitting the negative sign you get.

Plot two points or more. It is defined as the force needed to stretch or extend a string which is directly proportional to the distance you stretch it. To plot a straight line you only need two points.

In simple it is for finding the stretch of springs. A spring constant is a measure of a springs ability to resist compression and elongation. Where f is the force n k is the spring constant n m x is the displacement m positive for displacement negative for compression what is a spring constant.

You can also use the hooke s law calculator in. With a calculated slope of 0 154 our model is begin equation x 0 154m end equation where m is the mass in kilograms and x is the displacement in meters. Load 10 pounds.

Hooke s law states that the restoring force of the string is directly proportional to its displacement. Determine the displacement of the spring let s say 0 15 m. The easiest way to get values for a hooke s law graph is to suspend.

How to use the hooke s law calculator. F k x. The formula to figure out your spring constant from a known load and distance traveled is.

There are two simple approaches you can use to calculate the spring constant using either hooke s law alongside some data about the strength of the restoring or applied force and the displacement of the spring from its equilibrium position or using the elastic potential energy equation alongside figures for the work done in extending the spring and the displacement of the spring. Rate load distance traveled for example. Spring constant dimensional formula f force applied x displacement by the spring.

N m m n. How to calculate spring constant convert to force. Calculate a required spring constant the other way to calculate the compression spring constant on your spring is if you know the load you want to achieve at a certain distance traveled.

The following is hooke s law formula for determining the spring constant of a spring. Now we can finally calculate the spring constant. F kx now we need to rework the equation so that we are calculating for the missing metric which is the spring constant or k.

If you recall the equation above we used lambda to represent the slope where lambda g k. In order to figure out how to calculate the spring constant we must remember what hooke s law says. Substitute them into the formula.
