Worked Solution & Example Answer:Gears can be used to transmit forces - OCR Gateway - GCSE Physics - Question 11 - 2021 - Paper 1
Step 1
Which statement explains how these gears transmit forces?
Answer
To analyze how the gears transmit forces, we need to consider their rotational effects and how they interact with one another. When Wheel A is turned clockwise, it imparts motion onto Wheel B. Because gears are interlocked, the rotational direction of Wheel A affects Wheel B directly.
Since Wheel A is turning clockwise, Wheel B will turn in the opposite direction, which is counterclockwise. The size of Wheel A compared to Wheel B will influence how quickly Wheel B turns. If Wheel B has a larger radius, it would turn more slowly compared to Wheel A for the same movement. Hence, if Wheel B has a bigger rotational effect due to its size, it will turn more slowly than Wheel A. Consequently:
The correct answer is B: Wheel B has a bigger rotational effect and turns more slowly than wheel A.
