This research involves a failure analysis of the internal structural collapse that occured in the World Trade Center 5 due to fire exposure alone on September 11, 2001. It is hypothesized that the steel column-tree assembly failed during the heating phase of the fire. Abaqus/Standard was used to predict the structural performance of the assembly when exposed to the tire. Results from a finite element, thermal-stress model confirms this hypothesis, for it is concluded that the catastrophic,… Continue

Torque motors are also called "frameless" motors. They don't have housings, bearings, or feedback devices. In this sense the motor is a kit and meant to be part of the machine structure. Torque motors are designed as direct drives. They eliminate the need for gearboxes, worm-gear drives, and other mechanical transmission elements and directly couple the payload to the drive. This makes rotary drives with high dynamic responses and no hysteresis possible. The large inner diameter of a torque… Continue

When we first saw the horrible footage of the Japanese earthquake and the devastating tsunami that followed, who could have imagined the reverberations that have now been felt across the world’s energy sector?
The resulting damage to the Fukushima nuclear reactors have made many—from engineers to scientists to public officials—question the wisdom of our reliance on nuclear power, and its role moving forward.
One of the biggest developments has been German… Continue

I just came across an outfit called GrabCAD. It provides engineering services, as well as offers a pretty big library of free
3D CAD models. I'm interested in hearing from anyone who has used this service and what the experience was like.

The Mariner 5 spacecraft was launched in 1967 to carry a complement of experiments to probe Venus's atmosphere by radio occultation, measure the hydrogen hard ultraviolet spectrum, and sample the solar particles and magnetic field fluctuations above the planet. Data analyzed from Mariner 5 in 1971 found a small but… Continue

Ok. So this is a post about work - and work conflicts. Particularly between manufacturing and engineering.
I think that oftentimes, manufacturing and engineering are asked to work in parallel while being completely at odds philosophically.
Engineers deal with a lot of different… Continue

Though many kids his age are playing video games or cruising sites online, 7th grader Aiden Dwyer prefers to trek through the woods and study science. OK, so there are still some kids out there who do like to get out in nature, but my bet is they're building forts and burning things. Aiden, on the… Continue

GE says its experience with superconducting equipment from its healthcare MRIs is applicable to generators for wind turbines. High torque at low rotational speeds may let wind turbines product up to 15 MW and without a gearbox."]
GE Global Research, the technology development arm of GE, says it has begun work on the first phase of a 2-year, $3 million project from the U.S. Department of Energy to develop a next generation wind-turbine generator that could support… Continue
