• Each cuff has a rotating arm which engages with a ratchet that prevents it from being opened once closed around a person's wrist.
• It might include a solenoid brake and/or a mechanical brake or ratchet and pawl which prevents it unwinding unless the pawl is retracted.
• In evolutionary genetics, Muller's ratchet (named after Hermann Joseph Muller, by analogy with a ratchet effect) is a process which, in the absence of recombination (especially in an asexual population), results in an accumulation of irreversible deleterious mutations.
• A reading and writing table with an easel or double easel for books that was adjustable on a ratchet and a drawer fitted for writing implements was a mid-18th century English invention that lasted as long as the habit endured of reading while standing.
• These portions had raised stones perpendicular to the street at regular intervals acting like a ratchet so that carts and rickshaws could be easily stopped and parked.
• Although at first sight the Brownian ratchet seems to extract useful work from Brownian motion, Feynman demonstrated that if the entire device is at the same temperature, the ratchet will not rotate continuously in one direction but will move randomly back and forth, and therefore will not produce any useful work.
• A ratchet consists of a round gear or a linear rack with teeth, and a pivoting, spring-loaded finger called a pawl (or click, in clocks and watches) that engages the teeth.
• Reels for distance lines may have a locking mechanism, ratchet or adjustable drag to control deployment of the line and a winding handle to help keep slack line under control and rewind line.

• Most of these systems work with compression locks or electric motors instead of ratchet mechanisms; the latter may be capable of moving to a memorized position when a given driver uses the car or automatically moving up and forward to ease egress.
• When the pawl reaches its full stroke, it blocks the ratchet so it and the wipers will not overshoot.
• The timing chain rode on one pivoting chain guide resting on the ratchet tensioner and one fixed guide attached to the engine block and cylinder head.
• As the interrogation progresses, a handle and ratchet mechanism attached to the top roller are used to very gradually retract the chains, slowly increasing the strain on the prisoner's shoulders, hips, knees, and elbows and causing excruciating pain.
