Wheel and Axle Simple Machine: How It Works & Mechanical Advantage #3758906 (License: Personal Use)

This schematic depicts a classic wheel-and-axle system where an input force F₁ applied at radius r₁ on the wheel produces a greater output force F₂ at radius r₂ on the axle. The mechanical advantage is calculated as r₁/r₂, illustrating how rotational motion transfers and amplifies force efficiently. Arrows indicate direction of rotation and force vectors for clarity.
