In this apparatus the driven wheel has six slots and thus advances for each rotation of the drive wheel by one step of 60°.
An anodized aluminium disc is mounted on ball bearings as a driver. The disc has a scale so that the input angle can be exactly measured. The crank pin is to use for the movement of driven wheel. Driven Wheel is made of black anodized aluminum. All components are fitted to a HDF fitted with rubber feet. The unit is placed on the laboratory table for the experiment.
