Two shafts A and B are co-axial. A gear C (50 teeth) is rigidly mounted on shaft A. A compound gear D-E gears with C and an internal gear G. D has 20 teeth and gears with C and E has 35 teeth and gears with an internal gear G. Gear G is fixed and is concentric with the shaft Axis. The compound gear D-E is mounted on a pin which projects from an arm keyed to the shaft B.
(a) Draw the arrangement
(b) Evaluate TG.
(c) If shaft A rotates at 100 rpm, determine the speed of shaft B.
