DESCRIPTION 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. TECHNICAL SPECIFICATIONS Max angle of heel: ±13° Corresponding linear dimension: ±90mm EXPERIMENTAL CONTENT Determining the centre of gravity of the pontoon Determining the metacentric height and from this the position of the metacentre for the pontoon Varying the metacentric height with angle of heel
