F1-14 Basic Metacentric Height - Issue 19

This equipment enables a thorough investigation of the factors affecting the stability of a floating body.

Ordering Specification

• 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.
