How do you determine a spring constant?
The formula to calculate the spring constant is as follows: k= -F/x, where k is the spring constant. F is the force and x is the change in spring’s length.
How do you find the spring constant from Joules?
The letter k is used for the spring constant, and it has the units N/m. Like all work and energy, the unit of potential energy is the Joule (J), where 1 J = 1 N∙m = 1 kg m2/s2 . k = the spring constant, specific to the spring, with units N/m.
How do you find the spring constant from Youngs modulus?
In the elastic region, Young’s modulus and spring constant remain constant. In the equation, Y = σ/ε, i.e. Y = F*L/A*ΔL, ε is engineering strain, and L is initial length, not total length after the deformation.
What is a reasonable spring constant?
The larger the value of k, the harder it is to stretch the spring. Any spring that obeys equation (10.1) is said to be an ideal spring. The minus sign means that the restoring force always points in a direction opposite to the direction of deformation. A spring has a spring constant of 155 N/m.
What is the spring constant k value?
2.85 N/m
Reasoning: An ideal spring obeys Hooke’s law, F = -kx. Details of the calculation: k = |F/x| = (0.1 N)/ (0.035 m) = 2.85 N/m.
What is the spring constant of aluminum?
κts
κts is the spring constant of the transition state, in contrast to that of the formed bond (κ)….9.7. 2 Elasticity.

|---|---|
| Aluminum (rolled) | 6.8–7.0×1010 |
| Nickel | 20.01–21.38×1010 |
| Constantan | 14.51–14.89×1010 |

How do you calculate spring constant GCSE?
When an object, such as a spring, is stretched, the increased length is called its extension….Force on a spring.
| F = ke | F = k x e |
|---|---|
| k = | k = F ÷ e |
| e = | e = F ÷ k |
What is spring constant k measured in?
newtons per metre
spring constant (k) is measured in newtons per metre (N/m) extension (e), or increase in length, is measured in metres (m)
How do you find the spring constant of a spring?
The spring constant is given as: \\(k=-\\frac{F}{x}\\) = – 2 / 0.4= – 5 N/m. Example 2 A boy weighing 20 pounds stretches a spring by 50 cm. Determine the spring constant of the spring. Solution: Given: Mass m = 20 lbs = 20 / 2.2 = 9.09 Kg. Displacement x = 50 cm. The force F = ma = 9.09 × 9.8 = 89.082 N. The spring constant formula is given by:
How do you find the spring constant with Hooke’s law?
Using Hooke’s law is the simplest approach to finding the value of the spring constant, and you can even obtain the data yourself through a simple setup where you hang a known mass (with the force of its weight given by F = mg ) from a spring and record the extension of the spring.
What is the formula for spring constant F ma?
The force F = ma = 9.09 × 9.8 = 89.082 N. The spring constant formula is given by: = – 89.082 / 0.5 = – 178.164 N/m. Stay tuned with BYJU’S to learn more about other Physics related concepts.
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.
