Final answer:
If gear 1 is rotating clockwise, gear 3 and gear 4 will rotate clockwise if gear 2 is smaller and gear 4 is larger. The direction of rotation can change depending on the gear ratios and arrangement.
Step-by-step explanation:
When gear 1 is rotating clockwise, the direction of gear 3 and gear 4 depends on the gear ratios and the arrangement of the gears. If gear 1 is rotating clockwise, gear 3 and gear 4 will rotate clockwise if gear 2 is smaller and gear 4 is larger. The direction of rotation can change depending on the gear ratios and arrangement.
If gear 2 is smaller in size than gear 1, and gear 4 is larger in size than gear 3, then gear 3 and gear 4 will also rotate clockwise. This is because the smaller gear (gear 2) will make more revolutions per minute than the larger gear (gear 1), resulting in a clockwise rotation for both gear 3 and gear 4. However, if the gear ratios and arrangement are different, the direction of rotation can change.
