A 12-tooth external spur gear A, rotating clockwise, drives a gear B whose diametral pitch is 4. The ratio of the speed of gear A to gear B is 2 to 1. The tooth proportions are standard 14-12° brown and sharpe. (1) Placing the center of gear A on a vertical line above the center of B on the same vertical line show and give the diameters of the pitch circles, addendum circles, and dedendum circles. (2) Sketch in roughly enough of a tooth on each gear in contact at the pitch point and indicate the face of the tooth, the flank of the tooth and the pitch point.
