To calculate spring index you must calculate the mean diameter first.
How to calculate the stiffness of a spring. Spring index is the proportional ratio between the springs outer diameter and wire diameter. It is basically the tightness of your springs coils. If your spring coils are too tight theyre obviously under more stress thus making your spring stiffer.
To calculate spring index you must calculate the mean diameter first. This is done by subtracting one wire diameter from the outer diameter or adding one wire diameter to the inner diameter. This was discovered by the British physicist Robert Hooke in 1660 and stated as F k x where F is the force required to create a displacement of x in the position of a spring.
Sometimes this law appears with a negative sign and the meaning of the force reversed. String stiffness is the measure of the rigidity of an object. It is to compute the extend to which the string can resist the deformation in response to the applied force.
Find the stiffness of the string by using this online spring stiffness calculator. Enter the applied force and extension to calculate the stiffness applied force extension.

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. The equations for a laminated leaf spring vary slightly and are.
L Half the overall length of the longest leaf spring m F Force applied at each mounting point to the chassis usually half the load applied at the axle point m b Leaf spring width at the centre point m n number of leaves. Spring force F N. Spring outer diameter Dout D d 10-3 m.

Pitch of lead s L0 n 10-3 m. Shear stress τ 10 6 Pa. The formula for Hookes law specifically relates the change in extension of the spring x to the restoring force F generated in it.
F kx F kx The extra term k is the spring constant. The force constant k is measure of the stiffness of the spring. A small value of k indicates that the spring can be easily stretched or compressed.
In other words springs with lesser spring constants will have greater displacements than those with larger spring constants for the same amount of force applied. Sample Problem 31 1. An oscillating body takes 08 seconds to complete four cycles.
More generally two or more springs are in series when any external stress applied to the ensemble gets applied to each spring without change of magnitude and the amount strain deformation of the ensemble is the sum of the strains of the individual springs. For an elastic body with a single degree of freedom DOF for example stretching or compression of a rod the stiffness is defined as. K F δ displaystyle k frac F delta where F is the force on the body.

Multiply your springs rate per degree by the distance traveled in degrees as shown in the following formula. Load Rate Per Degree Distanced Traveled L RpD DT. Rotational stiffness can be defined as ratio of momentum to rotation.
The inverse of stiffness is termed as flexibility or pliability. Use this stiffness calculator to find the stiffness applied force and extension alternatively with the other known values. Code to add this calci to your website.
To calculate the torque applied half the difference between the scale readings in kg and multiply it by the distance between the front knife edges in meters. Finally multiply this number by the constant 981 to get your torque applied in newtons per meter.
