Textbook Problem

Technician A says that if a single idler gear is used to obtain reverse gear, its size and number of teeth must be used to calculate gear ratios. Technician B says that an idler gear is often used for reverse gear because it causes the output shaft to rotate in the reverse direction of the input shaft. Who is correct?

a. Technician A only

b. Technician B only

c. Both A and B

d. Neither A nor B

To determine

The technician with correct approach.

Explanation

Given:

Technician A says that if a single idler gear is used to obtain reverse gear, its size and number of teeth must be used to calculate gear ratio.

Technician B say that an idler gear is often used for reverse gear because it causes the output shaft to rotate in reverse direction of input shaft.

Gear ratio is defined as ratio of the total number of times the output shaft turns while the input shaft is turning once. The gear ratio is obtained by dividing the number of teeth on the driven gear by the teeth of driving gear. But if a single idler gear is used to obtain reverse gear, its teeth are not used in calculation of gear ratio...
