how to determine spring constant experiment

He began writing online inoffering information in scientific, cultural and practical topics. The spring in the shock absorber will, at a minimum, have to give you 2, newtons of force at the maximum compression of 0. The difference is x. The variables of the equation are: F which represents force, k which is called the spring constant and measures how stiff and strong the spring is, and x is the distance the spring is stretched or compressed away from its equilibrium or rest position.

spring constant definition

Looking only at the magnitudes and therefore omitting the negative sign, you get Time to plug in the numbers: The springs used in the shock absorbers must have spring constants of at least 4, newtons per meter.

The relationship between force and extension is a linear one, which means that if you plot a force vs extension graph, you'll get a straight line. The amount of force is characteristic of the spring and is represented by the spring constant, k.

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.

spring constant experiment

Updated August 14, By Chris Deziel When you compress or extend a spring, it exerts a force opposite the force you exert in an effort to return to its equilibrium position.

The force exerted by a spring is called a restoring force; it always acts to restore the spring toward equilibrium. They inform you that the car will have a mass of 1, kilograms, and you have four shock absorbers, each 0. You can still get a graph with a straight line and extrapolate a value of k from the slope even if you don't make these conversions, but the value for k will be in the wrong units and will be a different value than the one you obtain if you do the conversion.
