Question
In a simple gear system, identify the input gear and output gear in the following diagram: Gear A is connected to Gear B, where Gear A has fewer teeth than Gear B. Which gear is the input gear and which is the output gear?
Answer
Gear A is the input gear, and Gear B is the output gear.
Explanation
This answer is strong because it correctly identifies the roles of the gears based on their teeth count. The question tests the understanding of gear systems and their functions in transmitting motion.
Common mistake
Identifying Gears
Students often confuse input gears with output gears in diagrams, leading to incorrect explanations of gear functions.
To fix this, carefully label the gears in the diagram and remember that the input gear drives the output gear, which is affected by the direction of rotation.
