Base circle radius should be greater than the sum of the amplitude and the follower radius.

Too big a pressure angle implies inefficiency. How big does the base circle radius have to be so the pressure angle remains less than 25 degrees?

What is the effect on pressure angle of increasing or decreasing the follower radius?
