A team of New York University scientists has created a gear mechanism that relies on fluids to generate rotation. The invention holds potential for a new generation of mechanical devices that offer ...

Manual steering gears predate the Model T era. The typical layout is a column and shaft leading from the steering wheel to a frame-mounted gear mechanism. This steering shaft rotates left and right, ...

The teeth of a gear are designed to mesh with those of another gear. The interlocking teeth allow the gear to transmit torque to its partner without slipping. Two meshed gears can move in exact ...

Two spinners inside a circular container and surrounded by liquid with bubbles that help to visualize the flows. The left spinner is actively driven to rotate with a motor (not shown) and the right ...
