From pantographic linkages and split-handle designs to toggle openings and sliding chassis, these folding knives redefine ...

Consider the mechanism shown below made up of moveable links AB, BD and slider D. Link AB is rotating CCW at a constant rate. Point C is the center of rotation for BD, where point C is at the ...

Geologists report that a universal sliding mechanism operates for earthquakes of all depths -- from the deep ones all the way up to the crustal ones. The physics of the sliding is the self-lubrication ...

The packaging of eukaryotic genomes as chromatin evolved by accommodating the conflicting demands of storing, organizing and protecting the genetic information while ensuring its access as needed. The ...

Well-made tools and machines are useful without knowing the mechanism, but sometimes they are touched by taking their eyes off of their mechanisms. There is a site which introduces the mechanism of ...
