Two coplanar forces act on the rim of a wheel. The forces are equal in magnitude. Which arrangement of forces provides only a couple?
This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.
Adiagram showing two parallel forces of equal magnitude and opposite direction, acting horizontally on the left and right side of the rim.
Bdiagram showing two forces of equal magnitude acting towards each other along the same line on the top and bottom of the rim.
Cdiagram showing two parallel forces of equal magnitude and the same direction, both pointing upwards, acting on the left and right side of the rim.
Ddiagram showing two parallel forces of equal magnitude and opposite direction, one pointing up and one pointing down, acting vertically on the top and bottom side of the rim.
✓ Correct answer
D: diagram showing two parallel forces of equal magnitude and opposite direction, one pointing up and one pointing down, acting vertically on the top and bottom side of the rim.
