1.For the countershaft in Prob. 372, p. 138, assume the gear
ratio from gear B to its mating gear is 2 to 1.
(a) Determine the minimum number of teeth that can be used
on gear B without an interference
problem in the teeth.
(b) Using the number of teeth from part (a), what
diametral pitch is required to also achieve the
given 8-in pitch diameter?
(c) Suppose the 20_ pressure
angle gears are exchanged for gears with 25_ pressure
maintaining the same pitch diameters and diametral pitch.
Determine the new forces FA and
FB if the same power is to be transmitted.
