  2. Modelización de esculturas en la enseñanza de las matemáticas

    Gómez-Collado, M.C.; Puchalt, J.; Sarrió, J.; Trujillo, M.
    [EN] Throughout history the mathematics have been present in disciplines such as engineering, social sciences, architecture and also painting and sculpture. In this work we study the mathematical modelling of some sculptures of the artist Jaume Espí and we propose the removal of this material to be used in the teaching of mathematics. In addition, with the help of graphic design programs such as 3DStudioMax we open the perspective of extrapolating these sculptural works to the field of architecture.

  3. Diseño en arquitectura y modelización matemática

    Gómez-Collado, M.C.; Puchalt, J.; Sarrió, J.; Trujillo, M.
    [EN] In this work we present mathematical modelling as a design tool in architecture. Our thesis is that mathematics joint with a suitable software, such as Mathematica, are a source of ideas for creating forms in architecture. In this sense we have designed new architectural volumes using mathematics as a main tool. The results support our thesis, since the volumes created with Mathematica have nothing to envy to others created with specific software for designing.

  4. Una propuesta para trabajar la proporción desde el arte

  14. Contribuciones de la modelización al desarrollo de las competencias básicas

    Sol, Manel
    [EN] For many years modelling activities have not been a common practice in the classroom despite having a wide recognition of their educational interest. Burkhardt i Pollack (2006) justify it by a lack of supporting materials and Antonius et al. (2007) indicate an insufficient guidance on teaching strategies. From this starting point some ideas are proposed to overcome these difficulties. The article is organized in three sections. In the first section shown relationship between modelling and curriculum. Moreover, the catalan curriculum is highlighted as it promotes mathematical projects, in the secondary education. In fact, project research (Projecte de recerca) and...

  15. Círculos de Mohr: un laboratorio virtual para la enseñanza y el aprendizaje de estados tensionales planos

    Jiménez Mocholí, Antonio José; Giménez-Palomares, Fernando; Lapuebla-Ferri, Andrés
    [EN] Linear elasticity is a discipline that studies the elastic solid under external forces that generate a mechanical response in linear elastic regime. In particular, it is of special interest to study the stresses and strains at any point of the solid, which is known as the elastic problem. Moreover, the problem of plane stress state -that is, in two dimensions- it is very common in engineering. Prior to its study, it is necessary to first obtain the so-called stress state in the differential vicinity around a point of the elastic solid, then calculating the different values that can reach...

  16. Analysis of Oscillations in a Cableway: Wind Load Effects

    Gustincic, Jan; Garcia-Raffi, Lluís M.
    [EN] The purpose of this paper is to develop and investigate a non-linear model for analysing the reaction of a self-detachable cabin monocable ropeway exposed to a sudden deceleration and wind forces. The First and Second Newton's Law and Differential Equations are the basic tools for building the model. Furthermore a few basic considerations have been made about the air “dragging and lifting" forces that induce oscillations and vibrations in mechanical systems alike. All the numerical data used for the simulation was taken from a ropeway in the skiing site of Ravascletto-Zoncolan in the North- East of Italy.
