What direction does Wheel D turn compared to Wheel C?

• A. Clockwise and faster than C
• B. Clockwise and slower than C
• C. Counter-clockwise and faster than C
• D. Counter-clockwise and slower than C

Answer: (C)

Understanding the interaction between gears is crucial when analyzing their movement. In this case, if Wheel C turns in a specific direction, Wheel D, which is typically meshed with Wheel C, will turn in the opposite direction due to the nature of gear mechanics. When two gears mesh, the rotation of one gear will always cause the adjacent gear to rotate in the opposite direction. So, if Wheel C is rotating in a clockwise manner, Wheel D will rotate counter-clockwise. The speed at which Wheel D turns compared to Wheel C can be influenced by their respective sizes. If Wheel D is smaller than Wheel C, it will rotate faster. Given that the scenario specifies that Wheel D turns faster than Wheel C and does so in the counter-clockwise direction, this aligns with the factors of gear dynamics. Therefore, the correct answer reflects the mechanical relationship between the two wheels, illustrating how one wheel's clockwise rotation leads to the other wheel's counter-clockwise motion and highlights the effect of size on their relative speeds.
