Vertical stand improves the ball bar evaluation of coordinate measuring machines according to ANSI B89.4.1-1997. The stand does this by solving the deflection problems associated with the free-standing ball bar by providing an extremely rigid support for it. A heavy interference fit fixes the rigid 2-inch diameter, hard-surfaced vertical column into the massive 25-lb solid cast-iron base. The base's bottom has three hard, stainless-steel feet lapped flat and coplanar to provide a microinch stable location surface.

The 100% solar-powered airplane Solar Impulse 2 is prepping for its upcoming flight, becoming the first plane to fly around the world without using fuel. It's able to do so because of above-average performance by all of the technologies that go into it, especially materials.
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
