Engineering Materials

Engineering materials is a discussion led by Design News Contributing Materials Editor Doug Smock on important new developments and applications that affect mechanical design. Metals covered include all types of steel and nonferrous metals, in all shapes. Resins covered include nylons, polycarbonates, polysulfides, polyimides, and polybutylene terephthalate (PBT). Other materials covered include ceramics and rubber. Topics covered include materials enhancement, new applications, process technology, tooling, sustainability, and economic issues. Posts will include latest news from global events such as K 2007, the Alliance of Plastics Processors Annual Conference, the National Plastics Exposition, and the annual technical conference (ANTEC) of the Society of Plastics Engineers.

Tempered Glass, Steel Create Cantilevered Walk

A tempered glass bottom on a new cantilevered walkway will allow visitors to the Grand Canyon to look 4,000 feet straight down to the Colorado River. It's 10 feet wide and extends 70 feet from an anchor rock. The Hualapai Indian Tribe's Glass Walkway features 90 tons of glass and a million pounds of steel. A grand opening is set for March. Another footnote for scientists: According to a blog (citing an AP report), the Bush Administration supposedly won't let park officials reveal their estimate of the age of the park for fear of offending creationists. . Seems a little far fetched to me.
