A gear-set consists of a 16-tooth pinion driving a 40-tooth gear. The diametral pitch (P) is 2, and the addendum and dedendum are 1/P and 1.25/P respectively. The gears are cut using a pressure angle of 20°. Compute the circular pitch, the center distance and the radii of the base circles. In mounting the gears, the center distance was incorrectly made ¼ in longer. Compute the new values of pressure angle and the pitch circle diameters. (Ans. 1.57 in, 14...
