This is an animation of a Watt I six-bar linkage with a translating link that does not rotate (select the video to begin the animation). This is obtained using GeoGebra to execute a construction described by E. A. Dijksman in his book Motion Geometry of Mechanisms.
This video is a news report on the UCI California Challenge: KOCE video.
My iBook Kinematics and Polynomials is now available for preorder on iTunes. You can see a preview at this link. At 75MB it is considered a relatively large download.
The goal is a presentation of the analysis and synthesis of kinematic systems that relies on the theory of polynomials. I wanted to include some Mathematica code by means of video screen capture and some animations. The iBook format makes this convenient, however the size of the document increases rapidly with each video.
Currently, it can only be seen on an iPad, but this is supposed to change soon, because the OSX Mavericks operation system is to include an iBooks application.
My latest attempt at ePublishing is an iBook called Kinematics and Polynomials in Brief. It will be available on October 1, 2013. It is about 50 pages and includes six short videos, which unfortunately add up to about 75MB. This is about three times the size of Introduction to Theoretical Kinematics, though about half the number of pages. It is also about six times what is recommended for a book download.
The extra MB arise from short videos of Mathematica algorithms that perform example calculations presented in the text. Actually, most of the videos show me silently executing the Mathematica commands, but I do talk in two of them, which significantly increases their size. If you are interested in the Mathematica files, please contact me.
