Determine the number of pairs of teeth in contact and the angle turned through by the larger wheel for one pair of teeth in contact. Determine also the ratio of the sliding velocity to the rolling velocity at the instant; a- Engagement commences, b- The Engagement terminates, and c- At the pitch point.
