UPDATED: Minneapolis tragedy: How engineering technology measures stress
Instrumentation, sensors and wireless can be used to examine structures and find weakness.
In wake of the fatal Aug. 1, 2007, Minneapolis , MN , Interstate 35 bridge collapse , after recovery efforts are complete, investigations will begin to study the cause of the tragedy. Preliminary reports suggest that the bridge recently passed inspection, which may raise questions about engineering methods used for such inspections.
Engineering technologies helpful for structural testing include instrumentation and sensors that measure, record, and analyze corrosion, vibration, load, and metal stress and fatigue; wireless technologies that can help relay such data and information; and simulation software that can combine sensor input, design information, and historical data to help predict time to failure.

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
