Spring constant and a spring's decompressed length
I wonder why the decompressed/free length of a spring doesn't change the spring constant $k$. I'll give the equation for $k$ here:
$k = \frac{Gd^4}{8nD^3}$
For a fixed number of coils, if the free length was longer, wouldn't the resulting spring be…

Equation for calculating spring costant
I'd like to design some of my own springs in order to obtain some very specific forces for a project. There are plenty of guides on how to make an arbitrary spring, but none I've read explain how to make one in such a way as to obtain a specific…

Velocity over time of a mass on the spring
Imagine a spring with constant $ \mathrm{k = 2 \ N/m}$. A mass of $2 \ \mathrm{kg}$ is dropped on it. (Initial velocity $= 0$)
Letting $\mathrm{g = 10 \ m/s²}$ , we can calculate the max velocity of the mass will be $\mathrm{10 \ m/s}$ when the…

What is the spring constant of a steel wire?
Assuming a steel wire with a Young's modulus of 400 GPa, which has a 1 mm. square cross section and 10 meters in length, what would be it's spring constant?
It is understood that Young's modulus is the special case spring constant where the cross…

simple harmonic motion and center of mass
We choose a system to be a spring + a connected body. If we stretch the body and leave it, it will make a simple harmonic motion. The center of mass of this system is approximately the center of mass of the body because the spring has a negligible…

Why do springs have helical shapes? Why do we not use a cylindrical rod as a spring?
A spring is a mechanical flexible element and has to absorb energy from outside gradually. We are manufacturing springs in helical shapes on a large scale. What is the reason behind this?

What kind of spring is a flat piece of metal?
In clocks, we have seen a spring device used to engage the winding ratchet. The spring can take the form of a straight or slightly curved piece of springy metal, affixed at one end, with the other end holding the ratchet down into the teeth of the…

Spring in Clocks
Is the spring in a clock a torsion spring? As opposed to looking like a clothespin spring, its windings are all in the same plane, does it still work the same way?

How does position change if the damping force depends on velocity squared instead of linearly?
How would a graph of the motion of a spring over time change if the initial damping force depended linearly on velocity was changed to depend solely on velocity squared? and why would it change in that way?

Would a coiled spring with more rings produce more force when pressed and then released?
Suppose that you have 2 coiled springs. Both are equally tall, wide, and thick. One has more rings than the other; this means that one is longer than the other when made into a straight line.
Would the longer one produce more force when pressed all…

Is the spring "constant" still constant if the spring is circular?
Imagine a spring with a spring "constant" $k$ which is put on a part of a circular form, say a disc (a slice of a cylinder) with a groove around it to put the spring on. If we stretch the spring it doesn't slip off the disc and friction can be…

Elastomer vs metal spring
What properties should an elastomer have for it to be used as a spring?
I mean: if I load a metal-coiled spring within the spring's elastic limits and then remove the load, then the metal spring would quickly return back to its original…

Acceleration and energy for a spring
The example question is:
"a clock contains a pendulum arm with a mass of $3.5 \,kg$. If the spring constant of the arm is $1.0\, N/m$ and the maximum amplitude of the arm is $45$ cm, calculate the energy of the system and the maximum speed of the…

Where does spring force come from?
So we are studying about springs, as of noe, the assumption is that they are massless.
My teacher told me that when we extend a spring, or compress it, there is a force called the spring force which tries to reform the spring back it its original…
