Hooke’s Law is a principle of physics that states that the that the force needed to extend or compress a spring by some distance is proportional to that distance. This ability to return to a normal shape after experiencing distortion can be referred to as a “restoring force”.

The letter k represents the “spring constant,” a number which essentially tells us how “stiff” a spring is. If you have a large value of k, that means more force is required to stretch it a certain length than you would need to stretch a less stiff spring the same length.

In SI units, displacements are measured in meters (m), and forces in newtons (N or kg. m/s2). Therefore, the spring constant k, and each element of the tensor κ, is measured in newtons per meter (N/m), or kilograms per second squared (kg/s2).

The Spring Constant Formula is given as, k=-/frac{F}{x} where, F = Force applied, x = displacement by the spring.

As per the Hooke’s Law, if spring is stretched, the force exerted is proportional to the increase in length from the equilibrium length. The formula to calculate the spring constant is as follows: k= -F/x, where k is the spring constant.

Calculate the spring constant.

1. First rearrange F = k x to find k:
2. k = 3 ÷ 0.15.
3. k = 20 N / m.

Hooke’s Law The extension of a material or a spring is its increase in length when pulled. Hooke’s Law says that the extension of an elastic object is directly proportional to the force applied to it. if the force applied is doubled, the extension doubles. if no force is applied, there is no extension.

A stronger spring-with a larger value of k-will move the same mass more quickly for a smaller period. As the spring constant k increases, the period decreases. For a given mass, that means a greater acceleration so the mass will move faster and, therefore, complete its motion quicker or in a shorter period.

If you lower the amount of coils, you’ll increase the spring stiffness which is the spring’s rate. If you adjust the outer diameter or the wire diameter, you will affect spring’s force and stiffness as well.

Changing the stiffness can be done by changing any or all of the variables that control spring stiffness. One easy way to do this is to add a second identical spring in series with the existing spring. You will get twice the travel and half the stiffness. Or just buy a different spring.
