  • virtual laboratory with algodoo for the determination of the metacentric height of a rectangular vessel
    2019
    Co-Authors: Roberto Augusto Del Carpio Minaya, Yalmar Ponce Atencio
    Abstract:

    In the present work, a virtual laboratory using the Algodoo App was implemented in order to determine the metacentric height of a rectangular Ship in 2D. Experiments were carried out with different rectangular Ships, of different densities and geometries, which floated on a density fluid of fresh or salt water. Vertically and horizontally sliding pieces of different weights were placed on each Ship, causingtilt on the Ship, which could be measured for determining the stability gradient. Following, dispersion graphs of the vertical gravity center position versus the stability gradient were made, and with a linear data adjustment, the Ships transverse stability metacenter was determined. Finally, with a statistical treatment, the Ships metacentric height and its respective interpretation of the stability were determined. It was concluded that the method could serve as an option for instruction in understanding the stability of Ships and this method could serve as an option for instruction in understanding the stability of ships and in suggesting the future work with more complicated ship geometries.

  • On the buoyancy force and the Metacentre
    2009
    Co-Authors: Mégel Jacques, Kliava Janis
    Abstract:

    We address the point of application A of the buoyancy force (also known as the Archimedes force) by using two different definitions of the point of application of a force, derived one from the work-energy relation and another one from the equation of motion. We present a quantitative approach to this issue based on the concept of the hydrostatic energy, considered for a general shape of the immersed cross-section of the floating body. We show that the location of A depends on the type of motion experienced by the body. In particular, in vertical translation, from the work-energy viewpoint, this point is fixed with respect to the centre of gravity G of the body. In contrast, in rolling/pitching motion there is duality in the location of A ; indeed, the work-energy relation implies A to be fixed with respect to the centre of buoyancy C, while from considerations involving the rotational moment it follows that A is located at the Metacentre M. We obtain analytical expressions of the location of M for a general shape of the immersed cross-section of the floating body and for an arbitrary angle of heel. We show that three different definitions of M viz., the ?geometrical? one, as the centre of curvature of the buoyancy curve, the Bouguer's one, involving the moment of inertia of the plane of flotation, and the ?dynamical? one, involving the second derivative of the hydrostatic energy, refer to one and the same special point, and we demonstrate a close relation between the height of M above the line of flotation and the stability of the floating body. Finally, we provide analytical expressions and graphs of the buoyancy, flotation and metacentric curves as functions of the angle of heel, for some particular shapes of the floating bodies.Comment: 33 pages, 17 figures, 25 r\'ef\'erence
