Driving The Wind

Next door to A2 Wind Tunnel, where cyclists work on reducing their wind resistance like in this video, is a larger building, another wind tunnel. But this facility, called the AeroDyn Wind Tunnel, is not meant for bicycles. It is meant to test cars, either for NASCAR, land speed competitions or drag races. Several NASCAR racers, including Dale Earnhardt Jr. have brought their cars to this tunnel.

New Use for Coal Ash

Coal ash is a byproduct of burning coal to generate electricity and is often stored in ponds near power plants. But when coal ash spilled out of a Duke Energy storage pond into the Dan River, it focused attention on the problem of storing coal ash. While some is currently used in concrete, NC A&T Researchers are finding a new use for coal ash as a super strong building material.

What's My Story: Ph.D. Research Assistant in Chemistry

It took Tana Villafana some time to figure out that she wanted to be a chemist. She started out hoping to be a writer and a musician. But as things worked out, she got to combine her love of the humanities with her love of electromagnetism.

Ph.D. Research Assistant: employed by a university to conduct research while seeking to earn a doctorate degree. They are typically responsible to a principal investigator.

Riding the Wind

From cyclists to race cars, the motion of an object is determined by the sum of the forces acting on it. Those forces have both strength and direction and they can be observed and measured to predict future motion. Watch how an aeronautics engineer works with Newton's three Laws of Motion to test the best posture and helmet for a cyclist in a wind tunnel.
