Homework Help: physics

Posted by anne on Friday, July 3, 2009 at 10:12pm.

our class was given an extra credit assignment where we have to design a mobile that has both the net forces and torques = 0. i have all of the masses know i just don't know how to find radii. no two masses can be in the same position nor can they be at the center of mass...i;m just having a very hard time with this because of those conditions..help please!
