F1-14 MKII Metacentric Height


F1-14 MKII Metacentric Height

This equipment enables a thorough investigation of the factors affecting the stability of a floating body. The metacentre will produce stable and unstable equilibrium, a plumb-bob is suspended from a mast, indicating the angle of heel on a calibrated scale.


The position of the metacentre can be varied to produce stable and unstable equilibrium.

The equipment consists of a plastic rectangular floating pontoon where the centre of gravity 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.
