Basic Metacentric Height
Rectangular floating pontoon with mast
Variable centre of gravity via movable weights (transverse and vertical)
Clinometer indicates angle of heel
Educational software available as an option.
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 enables 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.
