How do you find the spring constant of a torsion spring?

To calculate the required torsion spring constant you must divide the torque in inch-pounds or newton-millimeters by the degrees of deflection thus leaving you with a torsion spring rate result measured in inch-pounds per degree or newton-millimeters per degree.

How would you design an experiment to measure the spring constant k of a spring using Hooke’s Law?

So the spring force equals the force of gravity. AndMoreWe can add the force of gravity to both sides. So the spring force equals the force of gravity. And we can now substitute in equations the force of the spring equals.

How do you find the torsion constant k?

The first equation that you quote purports to give the torsional constant in terms of the length and diameter of the rod and the shear modulus of the material of which it is made. The second version of that equation is the one to use, namely K=Gπd432L.

How do you measure a torsion spring?

Basically, you run a tape measure along the length of a spring, and take down the number of inches. Therefore, if your tape measure indicates that a torsion spring is 36 inches from one end to the other, that’s a 36-inch — or three foot — torsion spring.

How do you calculate coil springs?

To calculate the amount of spring rate you will need on order to meet your working loads, simply divide the load you will be applying on your spring by the distance you expect your spring to travel or compress under that load.

What is the torsional constant of a spring?

The torsion constant may be calculated from the geometry and various material properties. It is analogous to the spring constant of a linear spring. The negative sign indicates that the direction of the torque is opposite to the direction of twist.

How do you tell a left torsion spring from a right?

Another way to determine the direction is by the end of the spring. The end of a left-wind spring always points clockwise, while the end of a right-wind spring always points counter-clockwise. You can determine the wire size/diameter of your springs using this garage door torsion spring color code chart.
