Genetic? Then she must get it from her mother...

Still no answer. Tail between your legs. Damn that was fun!

No....tired and you were no longer amusing monkey boy.

And what is this "not entertaining enough" shit? Has all this just been a game to you? I thought you were here to help, not diddle yourself for kicks!

Yes, it has been. I see any interaction with you over the last week to have been my entertainment and my trying to do a public service introducing you to the real world.

If it hadn't been amusing, I would have quit long ago.

Could you please state the name of the Fortune 500 company you intern for as I would like to make sure I don't have mutual funds leveraging it.

I'd like to say "you remind me of myself at age <5,6,7>," but thankfully I was never that pathetic...

PureP, that's K.

You're making up for it now.

  I know Archer has broke "the wall" in his latest video, but I still have to ask,
would using weaker magnets towards the end of the chain help break the wall?
  I'm thinking about the wheel builders. I've seen pictures of stacks of magnets in the middle, to make them stronger(I guess), but I'm thinking more along the lines of strong to weak. Strong(BIG magnets) at 1:00 and weaker (small magnets) at 3:00. Most of the wheel attempts I see are using all the same size magnets.
  Would this help diminish the wall effect?

  Chap

PS The magnets on the rods would all be the same size, of course. They should still attract/repel the same, just not as much. I don't know.

Yes bud, you're getting it.

It's the concept of a ramp using strength instead of proximity.

Give it a try.

While Exx is either stoned, stubborn, or bent on my example that disproves "stored mechanical energy," I'd like to uncover the truth.

I will do so in nontechnical terms, so it will be easy to follow.

Okay, Exx's claim is the more energy used to build a machine, the more energy it banks, the more useful it becomes by making your job "easier."

I have already shown this to be false by my previous example that shows a machine that makes a job harder, now I will prove my point with a machine that makes a job easier.

Heres the job: you want to move your refrigerator 100 feet across the floor.

Okay, two ways to tackle the situation.

The first is to shove the fridge across the floor, having to fight huge amounts of friction.

PP

The second is to build wheels. Now, just for this example, let's pretend the energy needed to make and mount the wheels is equivalent to the energy used when pushing without wheels 10 feet. Now let's say the wheels reduce friction by 90% (or another 10 feet without). Now the total energy used is only 20% of the first situation, or 20 feet without.

Obviously in the second situation, the addition of the wheels pay off. We always have to do work to make the wheels, but we never get it back. Clearly, it costs energy to do.

What the REAL advantage is comes from the reduction in friction.

As I have said many times before, machines dont bank energy to re-contribute at a later time. If this were the case, then we should see advantage to the pulley.

To move a  FRIDGE

Walk into the lounge room, grab a rug, mat floor placement off some description I am sure that you may have noticed them (lady not home) do not roll up an expenditure of energy. Transport ( cost) device to fridge. Place at side of fridge fluffy side down.

Estimate, width of fridge allow say 6" on  width bunch device against side at base, lock with foot.
Apply leverage to central top of fridge, this will allow device to be slipped full length ( your calc's on length), when underneath tilt opposite side and extract, mat, rug, etcWhen

No constuction of  wheels or any all aviabale.

This item  has
as
Exx's has said Banked

may i enquire what went into the manufacturing  proccess of this final product that gave it the ability to reduced friction / decorative / functional a tool .

To produce such a useful article was beyond the original conept of the rug maker.

The production costs associated to make this a decorative  piece is !!!

Or something that, is more than  that it can also be very useful, that is produced, cost's absorbed

With respect's to all  Tired

Den,\

ps Have a go Archer

Silly boy, little do your realize you are helping prove my point!

If the rug manufacturer decides to use multiple dies in a big pattern rather than one color (extra energy), would this make the job easier?

If they decide to add tassles, would this make it easier?

No! In fact the tassles would probably make it harder as they would bunch up under the rug!

All that matters is how the device effects the system, not how the device came to be!

Still no answer to my simple question, only more personal attacks. Big man.

Here's another one for ya:

The task: lift a 10 lb block vertically 20 feet (same as before)

Assembly for BOTH methods: a 25 foot tall rig, winch mounted on top, electrical control panel at grade (again, this is for BOTH methods, "banked energy" is the same at this point)

User input for BOTH: push a button

Method 1: clip weight to winch cable, push button, weight lifts (no additional input or loss from system as described above)

Method 2: build a pulley on the ground AND lever directly above (when winch pulls, one end of the lever is pulled down, other end lifts weight). Additional construction energy: pulley AND lever, plus loading the weight onto the end of the lever. Additiona load: pulley AND lever friction.

So, two otherwise IDENTICAL systems, perform the same task with the same user input.

One costs far more energy to construct AND operate.

Where is the banked energy benefit now?

Wow! somebody actually mentioned Archer and tried something related to his wheel on this page of posts.
That's encouraging.
