When a small gear drives a larger gear, the output speed _____.

A) decreases and torque decreases
B) decreases and torque increases
C) increases and torque increases
D) increases and torque decreases

Output Speed

Refers to the speed at which a machine or a part of it, such as an engine or drive shaft, delivers power.

Torque Decreases

A condition where the force that causes rotation around an axis reduces, often affecting machinery performance.

Torque Increases

The enhancement of the turning force exerted by an engine or motor, improving the vehicle's ability to accelerate and maintain speed.

  • Understand the principles of gear dynamics, including the effects of gear size changes on speed and torque.

Final Answer :
B
Explanation :
When a small gear drives a larger gear, the output speed decreases because the larger gear takes more time to complete one revolution. However, the torque increases because the larger gear radius multiplies the force applied by the smaller gear.
