HM 150.06 Stability of Floating Bodies Show data sheet (pdf file) Print page
Technical Description

  In hydrostatics, the metacentre is an important point to be considered when assessing the stability of floating bodies. Stability refers to the ability of a ship to right itself from a heeled position. The metacentre is the intersection of the buoyancy vector and the vessel's axis of symmetry at a certain heel.
  The HM 150.06 unit can be used to study the stability of a floating body and to determine the metacentre graphically. In addition, the buoyancy of the floating body can also be determined. The experiment is easy to set up and is particularly suitable for practical work in small groups.
  The experiment is conducted in a tank filled with water. A transparent body with a rectangular frame cross-section is used as the floating body. Clamped weights that can be moved horizontally and vertically make it possible to adjust the centre of gravity and the heel.  
  The position of the clamped weights can be read on scales. A clinometer indicates the heel.
  The accessory HM 150.39 is available as an optional extra for further experiments with different frame shapes.
  The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
