Is not pulling a massless spring after hanging it equivalent to pulling it from both sides?
Let us hang a massless spring and pulled it downwards with force $F$. (You may neglect gravitational force or include it within $F$.) Let due to this the spring extended by $x$. Now let me pull the ...

How can the work-energy theorem be applied in case of a block impacting a massive spring?
We have a spring with uniformly distributed mass $m$ and stiffness $k$, with free length $x_0$ aligned with the $x$-axis, lying on a friction-less table. A block of mass $M$ is moving towards it along ...

Ambiguity in work-energy theorem for a system
in this question if I have to find max compression in spring then if I consider both block and spring as system and then apply work energy theorem then as I have written above that spring force is ...

Does this spring work with Hooke's law or not? [closed]
In the table is the data from the spring. In the y axis is the force in Newtons, and in the x axis is the extension in meters.
Edit: I found out the reason why this spring did not work as initially ...

Does the maximum amount of energy a spring can store depend on spring geometry?
I have two springs made from the same metal, one is a helical torsion spring, and one is a spiral watch spring.
Both springs contain the same volume of metal in their active region.
I wind up both ...

Solving the Fagnano's Theorem using Hookes law and a Rubber Band
The inscribed triangle in another triangle that has the least perimeter turns out to be the orthic triangle. There is a way to prove this using absolute geometry and considering the reflections, but I ...

Spring damping coefficient in series
I have conducted an experiment into the decay constant of a spring $\gamma$ but am wondering how the damping coefficient $b$ is related to the configuration of a spring system. Is there such thing as ...

Does an Internal Spring Force Contribute to Drag on Parallel Plates?
Consider a simple system of 2 parallel plates joined at one end by a hinge, with a spring under tension, attempting to push the plates apart. The plates are moving through a fluid with enough speed ...

Visualising the twist produced in every segment of an axially loaded compression spring
My understanding of the mechanism of axially loaded compression springs:
When loaded axially, a small twist is produced in every single element AB of the spring.
To explain what I mean more clearly, ...

Is the formula $\tfrac12kx^2$ valid even for a massive spring? [closed]
Problem (University Physics, 15th ed. by Young & Freedman challenge problem 6.93):
We usually ignore the kinetic energy of the moving coils of a spring, but let's try to get a reasonable ...

Ignore weight in simple harmonic oscillation ODE [closed]
In Kreyszig's Advanced Engineering Mathematics, he introduces ODEs for simple harmonic oscillations by combining:
$F=-kx$
and
$F=ma=mx''$
So we get the homogenous linear second order differential ...

Consider two blocks of unequal or equal mass connected to a spring. At max. extension of the spring why do we say that both blocks have same velocity?
I mean I can't seem to draw an intuitive reason for this? Is it due to momentum conservation or due to the fact that COM of both blocks will remain at rest if both blocks are considered as a system so ...

Action-reaction pair for work?
The work done in extending or compressing a spring is given by the formula $W=\frac{1}{2}k(x_{2}^{2}-x_{1}^{2})$,
where $k$ is the spring constant, $x_{1}$ is the initial extension/compression, and $...
