Ratchets are mechanical devices that allow motion in one direction while preventing movement in the opposite direction. They typically consist of a toothed wheel or bar and a pawl that engages with the teeth, enabling incremental movement. Ratchets are commonly used in tools like socket wrenches and in various machinery to control movement and ensure safety. Their design is essential for applications that require precise and controlled motion.
