Description

On this item the position of the metacentre can be varied to produce stable and unstable equilibrium. The equipment consists of a plastic rectangular floating pontoon, the centre of gravity of which can be varied by an adjustable weight which slides and can be clamped in any position on a vertical mast.

A single plumb-bob is suspended from the mast which indicates the angle of heel on a calibrated scale. A weight with lateral adjustment allows the degree of heel to be varied and hence the stability of the pontoon determined.

The equipment does not require a separate water tank as it may be used on the Hydraulics Bench by filling the volumetric tank.
