The object of this virtual lab is to determine the spring constant k.

How to calculate spring constant k. Where x is the size of the displacement. In equation form we write. F k x 80 0 15 12 n.

F kx. Hooke s law states that the restoring force of a spring is directly proportional to a small displacement. You can also use the hooke s law calculator in.

Choose a value of spring constant for example 80 n m. How to use the hooke s law calculator. The proportionality constant k is specific for each spring.

Units of spring constant are in either inches or millimeters. N m m n. K constant pounds of load per inch of deflection 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.

You find the spring constant by suspending weights from the spring recording the extensions and plotting a graph. 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. The you simply plug those values into the calculator above.

Therefore k frac f x dimension of f mlt 2 dimension of x l therefore dimension of k k frac mlt 2 l mt 2 the spring constant formula is given as k frac f x where f force applied x displacement by the spring. Substitute them into the formula. K is the slope of the graph.

To find the spring constant k of a spring use the spring constant equation below. The spring in the shock absorber will at a minimum have to give you 2 450 newtons of force at the maximum compression of. 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.

The rate of force required to move the spring 1 inch of distance or in millimeters the rate of force required to move the spring 1 millimeter of distance. The calculate the spring constant you need to measure both the force acting on the spring and the displacement caused by the force. The spring constant denoted by k is unique for each spring and is the proportionality factor in hooke s law which relates force to extension.

The definition of spring constant k. Determine the displacement of the spring let s say 0 15 m.
