read it again, MY machine has a 2 meter amd 8 meter swing ratio because of the weight relif in the centre as shown in the drawing and noted in the writing,

2 meters and 8meters, thats a mechanical advantage of 8/2=4 ok

but it also states you can use normal machines, 2 meters fall at the short end and 10 metres at the extended end. 1,2 kgs on the extension and 10kgs on the short end, that is 12 kilos of lift required for 20 kilos of free falling weight leaving you with 8 kilos of energy

2 meters and 10 is a mechanical advantage of 10m/2m=5

This means to lift 20kg on the left (negleting friction), you first of all need 20kg/5=4 kg on the right, you only have 1.2....c'mon Archer a fucking dumb blonde can understand this.

Put another way:

10kg moving through 2 meters is 10*2=20 kg.meters of work, 1.2 kg moving through 10 meters is 10*1.2=12 kg.meters of work.

12kg.m worth of energy (work) doing the lifting is LESS than the 20kg.m of work required so you are not 'LEFT' with 8kg.m of energy you are MISSING 8kg.m  worth of energy.

Only a complete moron could miss this.

not difficult at all, but apparently you have no concept of what you are talking about.

I have looked at the animation that
badassdjbynight
made.

Well, it is totally different to the concept that user
Broli
showed.

I agree that the animation from user
badassdjbynight
show just energy conversion and no gain comes out of it.

But with the concept user Broli
showed,I guess we can gain some energy.
I will try later today, when I have some free time to simulate the concept of user
Broli and post an animation movie.

Maybe Archer just did not explain it very well, I did not understand it until now
as I have seen Broli?s drawings.

By the way, there is also a Linux and Windows version of
this great PHUN physics animation software:

First, let me say that I am not an Archer apologist however.... if you squint at his graphic at the top of the page it shows a 1 meter short arm and a 10 meter long arm or 10:1 mechanical advantage and 1.2 kg will lift the 10 kg so he is correct. I think what he was saying is that the one meter arm travels through a 2 meter arc.

We are all here for different reasons, what makes you think that your reason for being here is the correct one?

It is clear from your post that you do not understand the benefits of a debate. It sounds like you have the same ideology as the crazy Christian crowd. You know the ones...the guys that locked up Galileo! Remember how well that one turned out?

So let me get this straight, if this was your forum you would remove the voices of reason in this thread?

If you play your cards right tbnz, maybe Archer will give you a signed copy of his favorite undies.

You want us to believe everyone here, has a different purpose/intention. Then you tell us all "Christians" have the same purpose/intention. This is bold face prejudice. You REAP, what you SOW.
