1. The problem statement, all variables and given/known data i've altered this image to be easier to read. ignore problem 1 except for the information given. the picture of the rotating object is for problem 2, which is the problem i need help with http://img32.imageshack.us/img32/3690/screenshot20091121at931x.th.png [Broken] 2. The attempt at a solution i've solved for 'w' when the rotating bar is vertical, as well as velocity tangential. my issue is the whole 'sweet spot' definition.
