Give one example of the application of a rack and pinion mechanism. - Leaving Cert Engineering - Question d - 2008

A rack and pinion mechanism can be effectively utilized in the steering mechanism of a car. In this application, the rotational motion of the steering wheel is transformed into linear motion, allowing the wheels of the car to turn. This mechanism enhances the precision of steering and provides better control over the vehicle.

Another practical example is found in a pillar drilling machine, where a rack and pinion system is employed to raise or lower the drill table. By adjusting the height of the table using this mechanism, the operator can accurately position the material for drilling.
