Chapter 13, Problem 13.14(choose chapter or problem)
By employing a pressure angle larger than standard, it is possible to use fewer pinion teeth, and hence obtain smaller gears without undercutting during machining. If the gears are full-depth spur gears, what is the smallest possible pressure angle f that can be obtained without undercutting for a 9-tooth pinion to mesh with a rack?
