Two mating involute spur gear of 20° pressure angle have a gear ratio of 2. The number of teeth on the
pinion is 20 and its speed is 250 r.p.m. The module pitch of the teeth is 12 mm.
If the addendum on each wheel is such that the path of approach and the path of recess on each side are
half the maximum possible length, find : 1. the addendum for pinion and gear wheel ; 2. the length of
the arc of contact ; and 3. the maximum velocity of sliding during approach and recess.
