What forces act on a Ferris Wheel?

A Ferris wheel experiences several forces, including gravitational force acting downward on the structure and the passengers, and normal force acting upward from the supporting structure. Additionally, centripetal force is required to keep the passengers moving in a circular path, which is provided by the tension in the wheel's axle and the wheel's structure. Friction at the axle and any wind resistance can also impact the wheel's motion, but these are generally minimal compared to the other forces.
