The crank mechanism is the functional group of machines that converts a uniformly rotating (rotational) motion into a reciprocating (translational) motion or vice versa. Crank mechanisms are used in engines, pumps or presses.
The unit can be used to demonstrate this conversion with either a fixed or oscillating cylinder. The experimental unit comprises a crank disk, connecting rod and cylinder. The connecting rod is connected to the crank disk on one side via a crank. Changing the position of the crank on the crank disk adjusts the crank radius in three positions.
