Question: 1 / 400

Which term is NOT related to gears?

Cogwheel

Pinion

Rack

Axle

Gears are mechanical devices that transmit motion and torque between parts of a machine, and terms associated with gears typically involve components that directly engage in this function.

Cogwheel refers to a circular gear with teeth that mesh with other gears or components. Pinion is a smaller gear that engages with a larger gear, playing a crucial role in gear systems. Rack, in the context of gears, often refers to a linear gear that meshes with pinions to convert rotational motion into linear motion.

In contrast, axle refers to a central shaft for rotating wheels or gears but does not directly pertain to gears themselves. An axle might support gears, but it is not part of the gear mechanism or its operation. Therefore, axle is the term that stands apart as it does not relate directly to the functions or components involved in gearing systems.
