A compound gear train is shown below. Gear A has 60 teeth, engaging with gear B
having 200 teeth. Gear C has 60 teeth and is attached to the same shaft as gear B. Gear
C meshes with gear D, which has 90 teeth. The initial speed of gear A is 120 r.p.m.
Calculate:
i) the movement ratio of the gear system
ii) the speed of gear D in radians per second.
