If w = 1.0 rad/s
0-----0-----0-----0
lenght 1 = 2 m
lenght 2 = 3 m
lenght 3 = 4 m
each circl is a object weighing 1 kg.
find center of rotation
and tension in the massless rods
getting center of rotation was easy
but tension..
well i know if there's 3 objects, to get tension, i used m*wsquare*r from each object to the center of rotation giving me 2 tensions, that worked, but with 4 objects, what do we do here. ( iknow we should get 3 tensions)
