How do you calculate how far a spring will stretch?
We can find the spring constant of the spring from the given data for the 4 kg mass. Then we use x = F/k to find the displacement of a 1.5 kg mass. The work that must be done to stretch spring a distance x from its equilibrium position is W = ½kx2.
How does the length of a spring affect the spring constant?
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.
How do you calculate the elastic potential energy of a spring?
Energy stored in a spring
- Work is done when a spring is extended or compressed . Elastic potential energy is stored in the spring.
- The elastic potential energy stored can be calculated using the equation:
- elastic potential energy = 0.5 × spring constant × (extension) 2
How do you calculate the length of a spring?
To calculate spring wire length per coil, you must subtract the wire diameter from the outer diameter in order to get mean diameter. Once you have calculated mean diameter, multiply it by pi (3.14); this will give you the length of wire per coil.
What is the length of the spring?
The free length of a spring is defined as the length of a compression spring without any force or load applied to it. The compression spring undergoes deflection when a force or load is applied to it.
Does the spring constant of a spring depends upon its length?
Yes, spring constant of the spring varies inversely with the length of the spring. Thus, More the length of the spring, less is the spring constant.
What is the spring constant of the spring?
The spring constant is a property of the spring itself that shows the linear relationship between the force and the displacement. The amount of mechanical energy stored and used by a spring then, is relative to the force and displacement—the harder a spring is pulled, the harder it pulls back.
What is K in elastic potential energy?
Spring potential energy equation k is the spring constant. The value of spring constant is always real and positive. The units are Newtons per meter; Δx is the deformation (stretch or compression) of the spring, expressed in meters; and. U is the elastic potential energy in Joules.
What is the spring constant k?
The spring constant, k, is a measure of the stiffness of the spring. It is different for different springs and materials. The larger the spring constant, the stiffer the spring and the more difficult it is to stretch.
What is the spring constant in physics?
In other words, spring constant is the force applied if the displacement in the spring is unity. If a force F is considered that stretches the spring so that it displaces the equilibrium position by x. The Spring Constant Formula is given as,
What is the formula of spring constant in Hooke’s law?
According to Hooke’s law, the force required to compress or extend a spring is directly proportional to the distance it is stretched. The formula of spring constant is given as: Where, F is the restoring force of the spring directed towards the equilibrium. k is the spring constant in N.m -1.
How do you find the elastic potential energy of a spring?
The force resists the displacement and has a direction opposite to it, hence the minus sign. You can find the elastic potential energy of the spring, too. Choose a value of spring constant – for example, 80 N/m. Determine the displacement of the spring – let’s say, 0.15 m. Substitute them into the formula: F = -kΔx = -80 * 0.15 = 12 N.
How do you find the force required to extend a spring?
According to Hooke’s law, the force required to compress or extend a spring is directly proportional to the distance it is stretched. It can be represented in an equation as F = kx, where F is the force applied, k is the spring constant and x is the extension of the object usually in meters.
