A connecting rod joins two moving pivots to another fixed pivot. This is how a pair of windscreen wipers works on a car, moving backwards and forwards together.

This converts the rotation of the wheels into moving the train forward through the tracks.

It consists of a flat bar with teeth, which meshes with a small cylindrical gear called the pinion. When the pinion rotates, it forces the rack to move in a straight line, and when the rack moves, it can rotate the pinion

  • Rack railways:

    Pinions on a locomotive engage a rack between the rails to provide traction on steep inclines.

The cutting action occurs during the forward stroke, while the return stroke is quicker, minimizing downtime and increasing productivity.

The piston acts as the slider, moving linearly within the engine cylinder. The crankshaft is the rotating component that has offset sections called "cranks". A connecting rod links the piston (slider) to the crankshaft (crank). As the piston moves up and down, the connecting rod pushes and pulls the crank, forcing it to rotate.
