ive asked this before but i was answered that what made me think a vertical balance should level to horizontal. well here is a reason:
http://www.pbs.org/weta/roughscience/series3/gold_rush/balance.html
if the weights are the same in both arms and you lean the balance 45º it will go to horizontallity but how? if the horizontal arms are equal in both sides and also the weight, how gravity level the balance if the axle is exactly in the middle of the bar?
how comes that gravity produces movement when the balance goes from vertical to horizontal without lowering the center of gravity of the balance?
