Name: Inclined Planes Simple Machines Inclined planes are used to help move heavy objects up a certain height Inclined plane: a simple machine that is used to spread out the force needed to move an object By moving in small, gradual steps instead of all at once, it becomes easier to move objects up a certain height They work by using a long surface to create a ramp where one side is higher than the other Objects can be moved up or down the ramp Moving an object gradually over a longer distance is easier than lifting it by hand Name 3 inclined planes you might see in everyday life: 1.______________________ 2.______________________ 3.______________________ Inclined planes are used when objects have to be moved up to a height that is difficult to lift up to by hand Instead of trying to lift an object up high all at once, an inclined plane will allow you to lift it gradually across a greater distance This allows you to push the object slowly up a slope which is easier to do! Inclined planes also make it easier to go down the ramp! Types of Inclined Planes Slope: the angle that the inclined plane is set up at The greater the slope, the more difficult it is to use an inclined plane Long ramps set at a low angle create an easy slope to move objects up This increases the mechanical advantage! Draw a diagram of an inclined plane: label the ramp, slope, and angle Build your own inclined planes! Draw diagrams of all the different types of inclined planes you and your group can create with the inclined plane kits: Label all the parts with the correct vocabulary! See how much weight each can move! What functions could they serve? .

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.

Find an example of any of the following kinds of simple machines. They may not look like machines, but they are. A machine is "any device that provides a mechanical advantage--that is, allows a limited amount of effort to do useful work in lifting or moving a load." Random House Encyclopedia the lever This kind of machine magnifies effort so it is easier to move a load. You will not necessarily see the fulcrum (the pivot). This is a kind of lever. What work does the lever help people do? the inclined plane This kind of machine is a ramp. The Ancient Egyptians probably used ramps to move the stones to build the pyramids. What do people move with this inclined plane? Connections--Sponsored by Kraft General Foods DePaul Center for Urban Education ©1992 the wedge A wedge is two inclined planes together. These are used to concentrate force. What work did these people use the wedge to do? What kinds of mathematics have people applied to make these tools? For example, each of these tools involves angles.
