Determine the displacement of the spring let s say 0 15 m. G modulus of rigidity of spring material pounds per square inch d wire diameter inches n number of active coils which is the number of coils subjected to flexure always less than the total number of coils.

Hooke S Law Calculating Spring Constants With Images Science

Plot two points or more.

How do you calculate spring constant. To plot a straight line you only need two points. How to calculate spring constant convert to force. 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.

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. You can also use the hooke s law calculator in. Spring constant dimensional formula f force applied x displacement by the spring.

Now we can finally calculate the spring constant. F k x 80 0 15 12 n. The spring in the shock absorber will at a minimum have to give you 2 450 newtons of force at the maximum compression of.

For example if you are calculating the spring constant of a compression spring using english measurements your value would be pounds of force per inch of distance traveled. Substitute them into the formula. How to find the spring constant example problem where f equals force m equals the mass of the object and g equals the acceleration due to gravity 9 8 meters per second 2.

In general you can find the slope. The easiest way to get values for a hooke s law graph is to suspend. If you are using the metric system your spring constant would be in newtons per millimeter of distance traveled.

How to use the hooke s law calculator choose a value of spring constant for example 80 n m. K spring constant f force x distance from equilibrium x 0 spring equilibrium position. N m m n.

If you recall the equation above we used lambda to represent the slope where lambda g k. Measure the slope of the force extension graph.
