Spring constant equation
What is the spring constant k?
k is the spring constant, in Newtons per meter (N/m), and x is the displacement of the spring from its equilibrium position. The spring constant, k, is representative of how stiff the spring is. Stiffer (more difficult to stretch) springs have higher spring constants.
How do you calculate spring constant GCSE?
F = keF is the force in newtons (N)k is the ‘spring constant’ in newtons per metre (N/m)e is the extension in metres (m)This equation holds as long as the limit of proportionality is not exceeded.
What is spring constant in Hooke’s Law?
This is known as Hooke’s law and commonly written: F = − k x boxed{F=-kx} F=−kx. Where F is the force, x is the length of extension/compression and k is a constant of proportionality known as the spring constant which is usually given in N/m .
How do you find k in Hooke’s Law?
Mathematically, Hooke’s law states that the applied force F equals a constant k times the displacement or change in length x, or F = kx. The value of k depends not only on the kind of elastic material under consideration but also on its dimensions and shape.
Does the spring constant change?
More generally, the spring constant of a spring is inversely proportional to the length of the spring, assuming we are talking about a spring of a particular material and thickness.
What is a normal spring constant value?
Spring constants are quoted for interaction at each fiducial, providing a range of 25–0.03N·m−1.
What is the formula for work done?
| One can calculate the work done by an airplane by using the equation: W = F x D For instance, if a model airplane exerts 0.25 Newtons over a distance of 10 meters, the plane will expend 2.5 Joules. | |
|---|---|
| Work | = F x D |
| = 0.25 * 10 | |
| = 2.5 Joules |
How can I calculate weight?
Weight is a measure of the force of gravity pulling down on an object. It depends on the object’s mass and the acceleration due to gravity, which is 9.8 m/s2 on Earth. The formula for calculating weight is F = m × 9.8 m/s2, where F is the object’s weight in Newtons (N) and m is the object’s mass in kilograms.
What is the formula for calculating spring load?

Mean spring diameter. where: d.
What is spring stiffness?
For an elastic body with a single degree of freedom (DOF) (for example, stretching or compression of a rod), the stiffness is defined as. where, F is the force on the body is the displacement produced by the force along the same degree of freedom (for instance, the change in length of a stretched spring)
How do you calculate spring stiffness?
F = -kx. The proportional constant k is called the spring constant. It is a measure of the spring’s stiffness. When a spring is stretched or compressed, so that its length changes by an amount x from its equilibrium length, then it exerts a force F = -kx in a direction towards its equilibrium position.
What is effective spring constant?
The spring constant was defined by k = |F/z|, where F is the force acting on the spring. and z the resultant deflection.
What affects the spring constant?
The spring constant can be determined based on four parameters: Wire diameter: the diameter of the wire comprising the spring. Coil diameter: the diameter of each coil, measuring the tightness of the coil. Free length: the length of the spring when at rest.
Is the spring constant always the same?
If you stretch a spring to double its initial length, then ideally it will keep the same spring constant (although if you exceed its elastic limit you may just ruin it). If you hook two identical springs together in series, or otherwise make a double-length spring, it will have half the spring constant.
