Question

In a gear system, the gear ration of the driving wheel A and driven wheel B is $10:1.$ To rotate the driven wheel B in the direction of driving wheel A, the driving wheel A is engaged with other wheel C. What should be the gear ratio of the wheels A and C ?

Answer 1

Given, gear ratio $=\frac{N_A}{N_B}=\frac{10}{a}$

It is possible to obtain a change in direction,

Using wheel C, if the number of teeth in

Wheel C is equal to the number of teeth in wheel A.

$\therefore N_C=N_A=10$

Hence, the gear ratio of wheels A and C:

Gear ratio $=\frac{N_A}{N_C}=\frac{10}{10}$

$\therefore$ The required gear ratio is $1:1$
