I am trying to figure out how to calculate the theoretical maximum angular
velocity of a rigid object but I just cant figure it out. I trying to calculate
Wmax for a cross shaped object rotating about the center point(+) in a
clockwise direction. It rotates clockwise beacuse I placed 4 equal forces at 90
deg. angles, one on each end of the cross, creating a clockwise moment. I
decided that the only way to calculate Wmax would be through conservation of
energy. The total energy of the rotating object could only of come from the
total amount of energy available due to the applied forces. (right?) So i used
two equations to calculate energy. KE rotate = (.5)IW^2 and KE = (Torque)*
(Theta). I have tried everything to try and solve this but I keep drawing a
blank. I keep finding that Wmax will be infinite which I know is impossible.
Any help would be greatly apprectiated. Thanks
