The answer I calcualted was 10 and I know that can't be correct because the coefficients of friction are always less than 1

**bobpursley**, Sunday, September 13, 2009 at 4:03pmYour suppostion about being less than one is incorrect. What if the object being moved were superglued to the surface. IT can be greater than one.

NOw, the prob.

Each bearing has 960/4 lb force vetically on it.

each bearing is getting 4lb force to maintain movement.

forcefriction=normal*mu

mu= 4/230
