  • Double Blade Flexure Animation of a Double Blade Flexure which is approximately straight line motion with no friction.
  • Sphere with Tunnel Brachistochrone The Wolfram Demonstrations Project contains thousands of free interactive visualizations, with new entries added daily. In theory, some transportation problems might be solved by digging a network of tunnels through the Earth connecting different cities (eg, New York and Tokyo). The idea is to use the Earth's gravity as the sole source of power to accelerate a train fr... Contributed by: John Snyder
  • The Tautochrone and Symmetry Course project: Juan Nunez, Rowel Ramirez, Brian Rojas Reflections in Space and Time California State Univ, Long Beach Spring 2010
  • Cycloid Curves The Wolfram Demonstrations Project contains thousands of free interactive visualizations, with new entries added daily. The curve traced out by a point on the rim of a circle rolling along a straight line is called a cycloid. Let the radius of the circle be a. Allowing the tracing point to be either within or without the circle at a distance b from the center generates "... Contributed by: Sean Madsen Additional contributions by: David von Seggern (U. Nevada, Reno)
  • Rotor Blade Profile idea (This video uses captions). Cycloid-like shapes are put together to create a shape that at a specific velocity and fixed pitch would minimize the time-path of air forced to travel over a moving object, possibly serving as a profile for a fixed pitch helicopter rotor blade.
  • Ciclóide
  • Brachistochrone, part 2 What's the fastest path between two points? A cycloid, the solution to the Brachistrochrone problem.
  • The Cycloid A more recent animation showing how a Cycloid is made. Way over done for what it was supposed to be but its pretty cool never the less
  • High Road Low Road Race Which car gets to the finish first?
  • Roller Coaster Project A roller coaster my group made for an APSC 100 project.
  • Roller Coaster Race Demonstration of the PASCO Roller Coaster system. Path of fastest descent.
  • Brachistochrone Problem
  • Brachistochrone - Slow Motion A slow motion demonstration of a Brachistochrone. A straight line may be the shortest distance between two points, but it is not the fastest path between two points!
  • Brachistochrone Problem The Wolfram Demonstrations Project contains thousands of free interactive visualizations, with new entries added daily. The brachistochrone problem asks for the shape of the curve down which a bead, starting from rest and accelerated by gravity, will slide (without friction) from one point to another in the least time.

  • Tautochrone Problem The Wolfram Demonstrations Project contains thousands of free interactive visualizations, with new entries added daily. Let a marble roll down a curved slope. In a tautochrone (curve of equal descent), the marble reaches the bottom in the same amount of time no matter where it starts. In a brachistochrone (curve of fastest descent), the marble reaches the bottom in the f... Contributed by: Ed Pegg Jr Based on a program by: Eric W. Weisstein
  • Brachistochrones The Wolfram Demonstrations Project contains thousands of free interactive visualizations, with new entries added daily. This shows the shape of the brachistochrone from the origin to a variable final point. The circles indicate the position of the sliding point at equally spaced times. Contributed by: Michael Trott
  • Brachistochrone An experiment from the Math-Exposition
  • Brachistochrone Race Which car gets to the finish line first? The Brachistochrone curve is the ideal path that gives the quickest descent. But in addition, the time from any starting point on the track to the bottom of the curve turns out to be the same value, independent of where the car is released. Thus not only do the two cars reach the bottom in the least amount of time possible, they both will always reach the bottom at the same time!
  • Catenary: The Hanging Chain The Wolfram Demonstrations Project contains thousands of free interactive visualizations, with new entries added daily. A catenary is formed by a hanging flexible chain, suspended from its ends and carrying only its own weight. Galileo Galilei (ca. 1600) believed that the chain would be a parabola. He wasn't right, yet he was close. Move the end points and change the len... Contributed by: Borut Levart
  • Brachistochrone What's the fastest path between two points? A cycloid, the solution to the Brachistrochrone problem.
  • Spheres on a Truncated Icosahedron The Wolfram Demonstrations Project contains thousands of free interactive visualizations, with new entries added daily. Spheres of variable size are placed on the faces of a truncated icosahedron. This arrangement can be used as a basis for showing the general appearance of certain icosahedral viruses.

  • cycloid video In this video a Calculus 3 makes an attempt at demonstrating the brachistochrone problem.
  • Brachistochrone at la Cite exhibit at La Cite, Paris. Misspelled title. oops!
  • Brachistochrone - Normal Speed Brachistochrone. Note that both troughs end beyond the lowest point on the curved cycloid. (This lowest point is shown by the resting white marble in the photo.) The marble on the straight path is always moving downward, but the marble on the cycloid path actually goes upward for the last part of its travel.
