The table unit is used for investigating a drum brake. The objective is to determine the
coefficient of friction. A ball bearing mounted anodised aluminium drum is driven by a rope
around its circumference loaded with weights. A further weight operates the ball bearing
mounted eccentric cams via a rope and thus the brake shoes in the drum. A direct comparison
of braking force to driving peripheral force is thus possible. The difference between a leading
and trailing brake can be simply demonstrated by reversing the direction of rotation.
