If shaft A turns one revolution How many revolutions does sh

If shaft A turns one revolution How many revolutions does shaft B turn? _____ How many revolutions does shaft C turn? _____ How many revolutions does shaft D turn? _____ if a torque of 10 ft lb is applied to shaft A. What torque would be required to balance this torque at shaft B? ______ C? _______ D? _____ What is the ratio of the gear train assuming shaft A is the driver and shaft D is the follower? ___________ Which shaft will turn the fastest? (circle one) A B C D

Solution

a)

i) As the gear ratio between A and B is 2, if shaft A rotates 1 revolution, shaft B will make 2 revolution

ii) As the gear ratio between B and C is 1.33, if shaft A rotates 1 revolution, shaft B will make 2.67 revolution

iii) As the gear ratio between C and D is 3.33, if shaft A rotates 1 revolution, shaft B will make 8.87 revolution
