HOLLY COW ITS AN   IN CINERBLASTER GO BATDUDE  Chet  seriously what is it BATMAN chet

Reluctant to post, so much aggro.

I am neither one way or the other as for or against AQ is concerned.

I see so much garbag said about light end versus heavy end.

So  very little about beam under slung fulcrum point.

Should not this as all idea's be considered.

A Question to you all what does the underslung balance point of this mechanism contribute?

Hey cub3! Glad you werent too intimidated to post.

To answer your question, this is something I have considered, and casually mentioned in a previous post or two. But since you ask, I will address it specifically.

When a lever is "slung" down as Archer's is (and mine for the demo), the lift/length ratios remains relatively unaltered. I say "relatively" because is does change some, but when the "slung" distance is only a couple inches compared to a few feet of beam length, the difference is very minor. Also, the difference would only be noticed as we tilt the beam further and further from horizontal. For a perfectly horizontal beam, the balance ratios would be identical regardless if it werent "slung" at all or if it were "slung" a mile.

This is because a "slung" beam shifts the center of mass vertically, not horizontally. A horizontal shift is the only factor that would change a levers balance/lift. Adding weights to the ends or sliding existing weights horizontally are examples of horizontal shift of the center of mass.

(I keep using "slung" for lack of a better word, not to mock you)

What the "slung" beam would have an effect on is how the beam comes to rest. In either case, the beam will always rotate so the center of mass is at the lowest possible position. For an "unslung," off-balance beam, this would be perfectly vertical. For a "slung," off-balanced beam, this would be at some angle determined by a number of variables (Please see attached picture for visualization). This is why old scales used for trade have a "slung" lever. When balanced, the center of mass is at the center of the lever, it moves below the fulcrum, and the lever is level. When unbalanced, the center of mass shifts horizontally so it is located somewhere other than the center of the lever and it comes to rest at some angle.

Hope this answers your question!
