This complex mechanism is a clever way to make gear F translate and rotate simultaneously.  The mechanism is pinned at point A, so the center of gear F travels in a circular path around point A.  Link ED drives the mechanism, and because it is pinned at E and D causing D to travel in a circular path around E and not around A.  Gear G must therefore rotate while point B moves in a circular arc around A.  For the angular velocity of 2.deltadeltadelatdelta rad/s and acceleration of .1rad/s^2 of link DE shown, find the angular velocity and acceleration of arm AC and gear F.
