Question

Three identical gears A B and C are used in power transmission. Gear A and C are input and output gears Gear B is an idler gear connecting A and C. The gear which is subjected to reversed nature of stress is

• A. A
• B. B
• C. C
• D. A and C

Hint:

In a gear system with an idler gear the input and output gears experience reversed stresses while the idler gear remains unaffected

Answer 1

The Correct Option is D

In a power transmission system utilizing idler gear B, gears A and C transmit power and rotate in opposite directions. As gears A and C are directly involved in power transmission, they experience reversed stress. Conversely, idler gear B does not transmit power and thus is not subject to reversed stress.
