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 = `"𝑁𝐴"/"𝑁𝐵"`= `"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.

∴ NC = NA = 10

Hence, the gear ratio of wheels A and C:
Gear ratio = `"𝑁𝐴"/"𝑁𝐶"`= `"10"/"10"`

∴ The required gear ration is 1:1
