[QUOTE="drewtwo99"]I'm a physics major and I can say that as long as the center of mass rests on a point under the table, you could suspend anything off of it in any fashion, as long as it is rigid and can't melt or warp due to gravity, temp, etc. So, the weight of the hammer head is under the table as you can see, and it far outweighs the mass of the ruler being held out. The ruler itself is being pressed down by the weight of the metal ring, but is also being pressed upwardly by the hammer's handle, in such a way that allows the hammer to hang suspended without falling. This is all possible due to friction reallyMrGeezer
I disagree.
As you can see, only the head is under the table, and only just barely. The thing is, in those types of hammers, most of the mass is actually in the HANDLE.
Don't believe me? Take a hammer like that, cut the head off, and weigh the head and handle separately.
Crap thats true, now im wrong again.....but still, the best way is to actually try it :)
