Low friction and long life on a lubrication-free pivot
This is a patented pivot that doesn't use lubrication, so it will work in a vacuum or super-clean area, and with no rubbing surfaces, it will also work in an unclean atmosphere without the problems of fretting or friction. With a radial design, the pivot has low hysteresis, center shift and thermal drift. The pivot uses springs with low cyclic stress, giving it an indefinite life, perfect for those critical, hard-to-get-at areas. It's often used in oscillating mirrors, lever linkages, instrument nulling, weighing machines, bearing preloading, gimbal rings, mirror positioning, scanners, fuel controls and pressure and vibration transducers. It has cantilever or double-ended support configuration.
The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
