https://en.m.wikipedia.org/wiki/Slinky

Slinky is a toy, a precompressed helical spring invented by Richard James in the early 1940s. It can perform a number of tricks, including travelling down a flight of steps end-over-end as it stretches and re-forms itself with the aid of gravity and its own momentum, or appear to levitate for a period of time after it has been dropped.

Physical properties Edit

The rules that govern the mechanics of a slinky are Hooke's law and the effects of gravitation.

Period of oscillation Edit
Due to simple harmonic motion the period of oscillation of a dangling slinky is

T
Where T is the time of the period of oscillation, m is the mass of the slinky and k is the spring constant of the slinky.

Equilibrium Edit
In the state of equilibrium of a slinky, all net force is cancelled throughout the entire slinky. This results in a stationary slinky with zero velocity. As the positions of each part of the slinky is governed by the slinky's mass, the force of gravity and the spring constant, various other properties of the slinky may be induced. The length of a perfect slinky with zero length when extended is

L
Where L is the length of the slinky, W is the weight of the slinky, and k is the spring constant of the slinky.

Due to the effect of gravity, the slinky appears bunched up towards the bottom end, as governed by the equation

p
Where n is a dimensionless variable, 0 ≤ n ≤ 1, with n = 0 corresponding to the top of the slinky and n = 1 being the bottom. Each intermediate value of n corresponds to the proportion of the slinky's mass above that point n, and p(n) gives the position that n is above the bottom of the slinky.

This quadratic equation means that rather than the center of mass being at the middle of the slinky, it lies one quarter of the length above the bottom end,

a garage door spring is literally the exact same design as a slinky tho. they are a different gauge of wire but it's literally the same thing in terms of shape and how they exert or store force.


a spring on a garage door has a function, slinkys do not provide that function - because they do not have continuous transfer of force from one end to the other.

What you are doing is saying Corkscrew pasta is a spring because it looks like a spring, science!

A slinky is a spring though. You cannot just distort objective words / definitions to fit your delusional worldview.

a spring on a garage door is a spring whether or not it is being used as it's function.

do you know what makes that spring a tension spring? it's rather simple actually, when stretched out beyond its normal shape it pulls with tension to return to that shape. oddly enough so does a slinky, as do all tension springs.

the only difference is the strength of the tension. as i said a door spring is of a thick enough gauge that it can fully return to its shape and overcome its own weight. whereas a slinky can not.

Bitches about me quote someone then posts copy pasta, solid. So the weight does not affect the supposed force of gravity. And a slinky does not have continuous spring recoil ability, its segmented recoil ability and only some of the force on each helical coil is transferred to the next coil as opposed to the whole thing acting as one. Sounds like more Nasa propaganda really.

Which doesn't prove it's not a spring. Try to keep up please

That illustrates it perfectly - its not a continuous force - its force is designed to be transferred through each coil separately and sequentially, not all at once, try to do that with a tension spring, it wont happen.

Thanks buddy.

We already talked about what makes a spring is the constant force (Post #82) traveling through the device so it acts as one solid piece, you just proved slinkys use segmented sequential transfer of force through its individual helical coils

Thanks again buddy!

Yes those are functioning springs, a slinky is just a helical coil that does not exert a constant tension from one end to the other - and so by any definition, its not a spring

Even though Nasa will try to tell you its a spring, this is what they do all the time, keep you confused and distracted.

Think about it, Nasa and Smithsonian Astrophysics are trying to tell you what a slinky is - dont you find that even remotely odd?


So, which part of the definition of a spring does a slinky fail to meet?

Quote
a resilient device, typically a helical metal coil, that can be pressed or pulled but returns to its former shape when released, used chiefly to exert constant tension or absorb movement.


...because what springs are used for is not the definition. When you pull a slinky apart and you let go of it, what happens? It returns to its former shape.

You can also use Merriam-Websters' definition:

Quote
an elastic body or device that recovers its original shape when released after being distorted


Which also perfectly matches a slinky.

No matter how you try to lie to everyone, a slinky is a spring.
