Question

In a gear system, the gear ratio 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 another wheel C. What should be the gear ratio of the wheels A and C?

• A. 1: 10
• B. 1: 1
• C. 2: 1
• D. 1: 2

Answer 1

The correct option is B

1: 1

The gear ratio of the wheels A and C should be 1$:$ 1. If the gear ratio of both the wheels of the gear system is 1, the driven gear rotates in the direction opposite to the driving gear.
