[TheForge] Little Giant / pulley / rpm / ???

[Bob]

     The ratio of the diameters between the 8" pulley and the 10" pulley 
is .8.
345 times .8 = 276 gives the same math result and is probably easier to 
understand
than the way I described it before.

Freedom is a fragile thing and is never more than a generation
away from extinction. It is not ours by inheritance; it must be
fought for and defended constantly by each generation, for it
comes only once to a people. Those who have known freedom and
then lost it have never known it again.
