Machine screw dimensions

According to Shigley and Mischke’s Mechanical Engineering Design (McGraw-Hill 1989) experiments show that the tensile stress supported by a threaded rod equals that of a rod with diameter that is the mean of pitch and minor diameters of the threads.  Thus, the tensile stress area of a threaded fastener is computed from the average of its […]

Engine Animation

This YouTube animation shows the animated assembly of a solid model of a four-cylinder engine.  It interesting just to see the number of fasteners, but it is worth waiting for the animation of the four-stroke cycle that occurs about two-thirds through.
