# Talk:857: Archimedes

What's Cueball trying to lift here that he needs a massive lever and fulcrum? __Davidy__²²`[talk]` 07:05, 17 April 2013 (UTC)

I think Cueball is just trying to gain *leverage*. -Justin- 131.111.141.12 20:39, 5 June 2013 (UTC)

- Cueball wants to move the earth with a lever. But how this should work in space? The hostage is the entire population of the earth. I will add an incomplete tag.--Dgbrt (talk) 21:34, 5 June 2013 (UTC)

- He is not saying he wants to move the Earth with a lever. He's either demanding the lever and a place to stand, threatening to kill hostages, or he's using a gun as a prop in a joke. Either way, the explanation is perfectly fine as it is, no "incomplete" needed. 108.28.72.186 02:44, 4 August 2013 (UTC)

How do you know his hostages are the entire population of earth? ~JFreund

Hey, I'm new here. I was thinking it would be more helpful if someone could give an example of a thriller movie with that quote. Thanks! 162.158.75.148 22:58, 24 March 2017 (UTC)

The comic and the title text seem to have a supervillain theme with planning to destroy/move the world and threatening to destroy the only antidote (to a presumably self-created plague/poison); the explanation doesn't really go into this apart from mentioning "action thrillers". 162.158.75.178 20:27, 26 February 2018 (UTC)

Could someone get into the Earth-moving math a bit more? The figures given sound wrong, but I'm not sure what kinds of assumptions we'd need to make before we could start calculating. -- GreatWyrmGold (talk) 01:51, 7 September 2022 *(please sign your comments with ~~~~)*

- Not about to do the sums, but for the earth-end fraction of Earth-fulcrum-person lever to move a distance, the person-end fraction must move distance*ratio(PEF,EEF). For fulcrum-Earth-person length=PEF, rather than length=(PEF+LEF), for a shorter lever due to re-using the fulcrum-Earth length, so that's perhaps the more economical setup.
- You need to swing a lever more than 60° (±30° from a given tangent) around its pivot to get the contact-point travel to go further than the length from pivot to CP (straight-line difference, or length*pi/3 tracing the radius), but at decreasing returns (you could never lever by more than twice the length (straight) or pi times it (semicircumferentially) from the pivot, at ±90° travel), so we might assume we set it up to do no more (though we could also calculate for the maximum).
- This sets us the distance from fulcrum to Earth, and then the force-multiplication needed for an average human's applicable strength is also the length-multipliple needed for fulcrum to person, allowing us to choose (according to setup, but in both cases overwhelmingly the fulcrum-person distance, so barely different) the appropriate full lever-length. And, having constrained the travel-angle, the person's travel-length (radially?) is directly calcuable.
- Or, to reverse, perhaps we can discover what assumptions that the Earth-moving figures might have arisen from. The simplest might be what angle of pivot it is, though not knowing if it's radial or direct displacement they give introduces us a small uncertainty, as does the order of contact-points. Less so than the force-multiplier demanded, though, given variations of human physiology. 172.70.86.4 09:02, 7 September 2022 (UTC)
