what were we talking about again?

Yeah, you never could tell with those guys...

Zook, you should look into these slinkies you talk about.. the workings of these strange objects may be expanded to contribute to our promethean goal!

The rest of us should work on the design for a thread esculator .

Then, nobody will be able to stop us! Nobody!

I like to laugh maniacally sometimes. It's lots of fun. So much so, that I don't even need a real reason to do so: I just let go with an booming evil laugh. I do get weird looks from the other passangers on the bus though.

skier · 09-17-2006, 09:45 AM

i'd probably get off at the next stop if I heard something like that. There are just some things you don't leave to chance.

Zooksport2 · 09-17-2006, 04:19 PM

I tried... I really did... But I can't get it to work. But I did find someone else who has tried... (performs handball)

Simanek's Silly Slinky Device
[New, November 2005] Back in the 1950s when I was an undergraduate student, some of us would relax from the rigors of homework by inventing mechanical devices as challenges to each other to figure out why they can't work. I found this one in my classical mechanics notes from those creative times. Here's the description designed to put the best face on it.

Two identical gear wheels (A and B) are connected by a frictionless chain drive (C). Obtain a Slinky (TM) toy or two, and make a chain of them to wrap around the outside of these wheels as shown. The coils of the spring engage in the gear teeth, which prevent the coils slipping on the pulleys. The design allows either one or two coils to fit in the gaps between the teeth. we show two coils per gap at the bottom, and one coil per gap at the top.

We have arranged things so that the coils are closer together on the right than on the left. We show a compression ratio of 2, but it can be anything you want. The chain drive (C) with ratio 2:1 keeps the lower pulley rotating half as fast as the upper one, maintaining the chosen compression ratio.

The internal forces are clearly balanced, so we need not consider them. Obviously the system is heavier in the right, since there are twice as many spring coils, so we expect the slinky and upwer wheel to rotate clockwise. As it turns, the compression ratio will be mainatained, and the unbalance maintained continually. The coils are expanded as they go around the top pulley, and compressed as they go around the bottom pulley, as indicated.

Of course, good engineering design will require two locked coaxial gears at the top and also at the bottom, to provide for proper tracking to give the spring lateral stability, otherwise it would fall off the gears. If you actually build one, its friction will prevent its motion. But it does move freely if either pulley is driven by hand, and it does does maintain the condition of overbalance no matter how far you rotate it. Now reduce the friction to zero and watch it go!

More power! The expected power output is proportional to the weight difference of the two vertical portions of the Slinky Spring. Therefore the power can be increased by increasing the length of the spring and the distance between the pulleys. This improved version is shown in the second figure. There is no limit to the improvement that can be gained in this way.

Even unworkable devices should be well-engineered.

Suspended springs do not have uniform spacing between loops. That isn't shown in the picture, but it isn't an issue affecting the performance of this device. What's important is that there be more spring loops on one side than the other at all times and the belt (C) functions to maintain that condition.

What an elegantly simple concept! If we build it, will it turn? As usual, we allow you to use perfect components, frictionless bearings, etc. Discussion and solutions are invited.

Ch'i · 09-17-2006, 10:12 PM

Haha! The double post.

skier · 09-17-2006, 11:09 PM

We can make multiple posts without them being appendiced? A boon if it is true

This is my first consequtive post

alas, it remains single posts. How did Chi get away with it?

If anyone possesses the power to make this thread infintely long, it is Ch'i.

For Ch'i has surpassed the laws of the regular TFP mortals and successively created a double post.
If it is possible to develop frictionless, perfect devices, such as a thread esculator, Ch'i can do it.

We're counting on you, oh mighty one.

CSflim · 09-18-2006, 05:42 AM

Ch'i! Reveal your secret at once! Have you mastered the dark arts?

Ch'i · 09-19-2006, 05:14 PM

Alas! It has fallen on me to take drastic measures to ensure this thread's longevity. The mastery of the double post is nearly mine. It comes at a price, however... my very soul! So stand elated at this dark activity, and ignor the fell price of this deed! I will do what I must.

Zooksport2 · 09-19-2006, 06:19 PM

.... and ?????????

biznatch · 09-19-2006, 10:07 PM

Patience, O Zooky one. Ch'i uses his power not on command, but at his will. I think.

Zooksport2 · 09-19-2006, 10:25 PM

But I was being patient. I waited an hour! Do you think I should wait a bit longer????

Ok.... I'll wait a bit longer.........

Ch'i · 09-20-2006, 10:59 PM

I'd like to take this time to point out how delicious pancakes are.

Zooksport2 · 09-21-2006, 01:06 AM

Now......????

CSflim · 09-21-2006, 04:25 AM

What are we waiting for?

biznatch · 09-21-2006, 05:19 AM

Well...let's sill continue posting, while Ch'i prepares to initiate the process of gathering up his force that will allow him to start to get ready to use his power.

Ch'i · 09-21-2006, 03:25 PM

Now I know what Einstein was worried about....

Zooksport2 · 09-21-2006, 03:40 PM

Now can I???

CSflim · 09-21-2006, 04:01 PM

Everyone sits still, in silence, with a close eye on Ch'i, waiting expectantly.....

chalk up a nudder post..
