One: describe the acceleration vectors of an object dropped off a rotating ring in freefall, from the non-newtonian perspective of an observer on the ring surface, who is rotating with the ring. The observer is defined to be at zero velocity, and non-rotating. Two, not as hard I don't think: Given, hm, a torsional force (sorry if I don't get the terminology right, haven't taken physics in over a year) of 500 N applied at 1 meter from the axis of rotation (I think that makes sense?), and a lever arm of 1 meter, and each of the counterweights has a mass of 20kg, What angle will the lever arms make with the vertical at equilibrium?
