If link DE has the angular motion shown, determine the respective angular velocities of gear F and crank AC at this instant, and the angular acceleration of crank AC. Given: rad ωDE = 4 s rad α DE = 20 2 s a = 100 mm b = 150 mm c = 100 mm d = 50 mm r = 75 mm θ = 30 deg Solution: ωG = 1 Guesses rad s ωAC = 1 rad s 478 ...
