Todays stupid question.

If you put a slinky on a escalator thats going up, and the slinky is going down, what would happen?

It's gonna just keep walking down the stairs.

Hm... On second blush, does this depend on the speed of the escalator? Hm. Not trivial. Might have to work out some equations to see if the slinky is automatically synched with any given speed of the escalator. Damn. I hate these kinds of questions just when I freakin' need to sleep.

But my gut instinct, from having played with so many slinky's over the years, is that it will just march in place.



[Your question, BTW, is the ever-so-slightest bit Mertonesque, from what I know]

My question was too smart for a Merton question, because it requires thinking to a certian degree.

Slinky will step down at a constant speed (result of gravity and spring stiffness). The escalator's speed will have to be adjusted to keep the Slinky in one place.

Duuuuuuuuuuuuuude, sounds like perpetual motion to me. You just violated all laws of physics and CREATED energy. Like cooooooooooool. Now lets go blow somthing up.

Actually, if speed is synched, it's not perpetual motion, simply a balanced energy system.

Think of it like this:

The slinky is not a separate device, but another virtual cog in the machine. The escalator is providing it with kinetic power, and the escalator motor is providing it with an infinite vertical region to play in.

Now, the only downfall to this is how deep escalator steps are. They are around twice the depth of the 1950s staircase steps a slinky was designed to go down on. This means you need an escalator with specially designed steps to maintain the proper motion, otherwise you have both step-dropping, and horizontal movement.

That horizontal movement is incredibly inefficient, and will make it near impossible to have a seemingly perpetual movment.

the slinky will get caught in the escalator causing it to stop, and then security escorts you out.

damn, i gotta go check my steerer tube for scratches now. I think that most escalators ascend faster than slinkies descend, so I am pretty sure the thing would end up at the top pretty soon. Still, the slinkie is such a wonderful toy, as it it fun for a girl and a boy.
