The easiest way to get values for a hooke s law graph is to suspend. Hooke s law states that the restoring force of the string is directly proportional to its displacement.

They inform you that the car will have a mass of 1 000 kilograms and you have four shock absorbers each 0 5 meters long to work with.

Finding the spring constant. Hooke s law spring constant calculator. How to calculate spring constant convert to force. How to find the spring constant example problem suppose that a group of car designers knocks on your door and asks whether you can help design a suspension system.

That is elasticity is directly related to the force constant. Plot two points or more. Measure the slope of the force extension graph.

It is defined as the force needed to stretch or extend a string which is directly proportional to the distance you stretch it. The spring constant k equals 0 1 the initial length is 2 meters and the final length is 7 meters this means that the extension x must be 7 2 which equals 5 meters. The spring constant is the force applied if the displacement in the spring is unity.

The spring constant is determined using the value of the force applied and the displacement caused by force on the spring. This value is also a measure of elasticity. This force follows hooke s law which relates the force of the spring to the spring constant and the displacement of the spring from its original position.

F restoring force of the spring directed toward equilibrium k spring constant units n m. In general you can find the slope. A spring constant is a measure of a springs ability to resist compression and elongation.

So the restoring force was 0 5 newtons. Plug these numbers into hooke s law and solve for f and we get negative 0 5 newtons. Using hooke s law is the simplest approach to finding the value of the spring constant and you can even obtain the data yourself through a simple setup where you hang a known mass with the force of its weight given by f mg from a spring and record the extension of the spring.

The higher the spring constant the harder it is to compress or stretch it. To plot a straight line you only need two points. Force of the spring spring constant k displacement f kx.

In simple it is for finding the stretch of springs.
