  • The Hay Inclined Plane in Coalbrookdale (Shropshire, England): Geometric Modeling and Virtual Reconstruction
    S S symmetry Article The Hay Inclined Plane in Coalbrookdale (Shropshire, England): Geometric Modeling and Virtual Reconstruction José Ignacio Rojas-Sola 1,* and Eduardo De la Morena-De la Fuente 2 1 Department of Engineering Graphics, Design and Projects, University of Jaén, Campus de las Lagunillas, s/n, 23071 Jaén, Spain 2 Research Group ‘Engineering Graphics and Industrial Archaeology’, University of Jaén, Campus de las Lagunillas, s/n, 23071 Jaén, Spain; [email protected] * Correspondence: [email protected]; Tel.: +34-953-212452 Received: 9 April 2019; Accepted: 22 April 2019; Published: 24 April 2019 Abstract: This article shows the geometric modeling and virtual reconstruction of the inclined plane of Coalbrookdale (Shropshire, England) that was in operation from 1792 to 1894. This historical invention, work of the Englishman William Reynolds, allowed the transportation of boats through channels located at different levels. Autodesk Inventor Professional software has been used to obtain the 3D CAD model of this historical invention and its geometric documentation. The material for the research is available on the website of the Betancourt Project of the Canary Orotava Foundation for the History of Science. Also, because the single sheet does not have a scale, it has been necessary to adopt a graphic scale so that the dimensions of the different elements are coherent. Furthermore, it has been necessary to establish some dimensional, geometric, and movement restrictions (degrees of freedom) so that the set will work properly. One of the main conclusions is that William Reynolds designed a mechanism seeking a longitudinal symmetry so that, from a single continuous movement, the mechanism allows two vessels to ascend and descend simultaneously.

  • The Amazing Normal Forces
    THE AMAZING NORMAL FORCES Horia I. Petrache Department of Physics, Indiana University Purdue University Indianapolis Indianapolis, IN 46202 November 9, 2012 Abstract This manuscript is written for students in introductory physics classes to address some of the common difficulties and misconceptions of the normal force, especially the relationship between normal and friction forces. Accordingly, it is intentionally informal and conversational in tone to teach students how to build an intuition to complement mathematical formalism. This is accomplished by beginning with common and everyday experience and then guiding students toward two realizations: (i) That real objects are deformable even when deformations are not easily visible, and (ii) that the relation between friction and normal forces follows from the action-reaction principle. The traditional formulae under static and kinetic conditions are then analyzed to show that peculiarity of the normal-friction relationship follows readily from observations and knowledge of physics principles. 1 1. Normal forces: amazing or amusing? Learning about normal forces can be a life changing event. In introductory physics, we accept and embrace these totally mysterious things. Suddenly, normal forces become a convenient answer to everything: they hold objects on floors, on walls, in elevators and even on ceilings. They lift heavy weights on platforms, let footballs bounce, basketball players jump, and as if this was not enough, they even tell friction what to do. (Ah, the amazing friction forces – yet another amazing story! [1]) Life before physics becomes inexplicable. This article is about building an intuition about normal forces using the action-reaction law of mechanics and the fact that real objects are deformable.

THE ENIGMA OF THE INCLINED PLANE FROM HERON TO GALILEO 1 Sophie Roux and Egidio Festa The law of the inclined plane states that the ratio between a weight and the force needed to balance this weight on a given inclined plane is equal to the ratio between the length and the height of this plane. With the peremptory tone for which he is known, Descartes affirmed that this law was 2 known to “all those who write about mechanics”. Yet the problem of the inclined plane appears neither in Aristotle nor in Archimedes, and while writers such as Heron of Alexandria, Pappus of Alexandria, Leonardo da Vinci, Girolamo Cardano, and Colantonio Stigliola do indeed formulate it, they do not find the solution.

Ancient people and modern people use machines for the same reason. They help us get work done, build roads and buildings, and move from one place to another. What is the definition of a machine? Amachine is anything made by people which makes work easier to do. When most of us think of a machine we think of big, noisy ones, such as a car, a bus, or a tractor. But did you realize that a hammer, a nail, a pair of scissors, an ax, a wheelbarrow, and a corkscrew are machines, too. All of these things are machines because they are made by people and make work easier to do. 3 Work, Force, and Load When scientists use the words force, work, and load, they use them differently than we use them in everyday conversation. Let’s better understand these words by thinking about a trip to the grocery store. Scientists define force as “a push or a pull”. When you push a grocery cart, you are applying a force. Scientists define a load as the object being moved by a machine. Scientists define work as “a force acting on a load to move it across a distance”. When you push a grocery cart in the store, the cart of groceries is the load, and your push is the force.
