Dec 11, 2020 · What is Spring Force. When a metal spring is stretched or compressed, it is displaced from its equilibrium position. As a result, it experiences a restoring force that tends to retract the spring back to its original position. This force is called the spring force.
Mar 12, 2024 · The simplest oscillations occur when the restoring force is directly proportional to displacement. This is called Hooke’s law force, or spring force: \[F=-k x. onumber \] Here, \(F\) is the restoring force, \(x\) is the displacement from equilibrium or deformation, and \(k\) is a constant related to the difficulty in deforming the system ...
Hooke's law. When studying springs and elasticity, the 17ᵗʰ century physicist Robert Hooke noticed that the stress vs strain curve for many materials has a linear region. Within certain limits, the force required to stretch an elastic object such as a metal spring is directly proportional to the extension of the spring.
- What is nominal length?nominal length = original/initial length
- I didn't understood what that minus in formula was for?It just tells us that the exerted by the spring will be in the opposite direction to the force applied.
- The spring constant is the same for all springs or different? explain.It varies between spring to spring, depending on what it is made of, the shape of the spring, and the width of the wire.
- is spring constant is same on another planet?gravity won't change the rigidity of the spring, so I think it is the same on other planets
- I have a question on example 2a. If the nominal length is 50mm, and the compression is of 50mm then ...The nominal length is 50m. But the spring is being extended not compressed and therefore, the formula is L = Li + x= 50 mm +50 mm = 100 mm
- I don't understand what the length notations of springs refers to. For example, strain is defined as...The spring has some length when it is relaxed, right? That's the initial length.
- Why is k=E.A/L? if we put K = -F.x and E=stress/strain = (F/A)/(x/L) = F.L/(A.x) then we get -F.x = ...I think we are only interested in the absolute value. You need not include the negative sign.
- in exercise 1, when we divided F over K, why the K isn't negative as hooke's law said?Hooke's law doesn't say that the constant k is negative. The negative sign is only saying that the force is in the opposite direction of the displa...
- In exercise 1, how come the F (force) is equal to mg, not mgh? When the person steps on, there is st...I think you're confused as to the difference between gravitational force and potential energy. Close enough to the Earth's surface, we always feel...

An important feature of periodic motion is that the object has a stable equilibrium position. Also, a restoring force which is directed toward that position. Spring has the application of force. This topic will explain the spring force concept and spring force formula with examples. Let us learn it!
Spring force. A spring is a special medium with a specific atomic structure that has the ability to restore its shape, if deformed. To restore its shape, a spring exerts a restoring force that is proportional to and in the opposite direction in which it is stretched or compressed.
This fact tells us that spring exerts an equal as well as an opposite force on a body which compresses or stretches it. The Spring force formula is given by, F = k(x – x 0) Where, the spring force is F, the equilibrium position is x o the displacement of the spring from its position at equilibrium is x, the spring constant is k.
