The MEP Systems That Can’t Afford to Stay Manual Most buildings don’t fail dramatically. They drift. A tenant complains that one side of the floor is too warm. The maintenance team bumps a setpoint. A booster pump gets noisier, but it still holds pressure. A panel schedule is “mostly right,” except for the circuits that no one updated after the last buildout. Nothing looks broken enough to stop t…

A centuries-old vision of a mechanical volcano has finally erupted into reality, as two University of Melbourne engineering students recreated a design first imagined in 1775 by volcanology enthusiast Sir William Hamilton. Drawing from an 18th-century watercolor and a preserved sketch, they used modern tools like LED lighting and electronic systems to simulate the glowing flows and explosive dram…

Laser welding is used to join thin metal parts. At high speeds, it can leave bumps on the surface of the metal that make the weld weaker. Scientists used a powerful X-ray camera to take images during the welding process, which revealed key causes of the bumps forming.

Am I doing this correctly? Given variables: ##R_b## = base circle radius ##R_f## = roller radius ##e## = offset (positive as shown in figure) ##\Delta R## = follower displacement from home position ##\frac{\nu}{\omega_{\rm{cam}}} = \frac{ds}{d\theta}## = slope of displacement diagram... Read more

With a black cloth draped over months of work, anticipation built earlier this month as the University of Florida’s Solar Gators prepared to reveal the next evolution of their solar-powered race car.  When the cover finally dropped, applause and possibility filled the room as Flare — sleeker, larger and reengineered — marked the team’s latest […]

As a boy in India, Anil Rajvanshi often found himself at the train station intently observing locomotives and dreaming.  “I just would stand in front of this huge steam engine and be mesmerized,” recalled Rajvanshi, Ph.D. “I thought that the best thing in the world would be an engine driver. And then I found this […]

Wake turbulence modeling in stratified atmospheric flows using a novel k−ℓ model Klemmer, Kerry S; Howland, Michael F As turbines continue to grow in hub height and rotor diameter and wind farms grow larger, consideration of stratified atmospheric boundary layer (ABL) processes in wind power models becomes increasingly important. Atmospheric stratification can considerably alter the boundary laye…

Hi - I'm trying to design a Rotisserie for fabrication of large UC beams, and could do with some physics help if possible please. The idea is... I'll create collars to allow a UC beam to turn on a set of rollers during fabrication process. The largest item I have weighs in at 4225kg including... Read more

I made a CVT (Continuously Variable Transmission) that uses two differentials to first split power between two gear ratios based on torque (1:1 and 2:1), and then recombine the separate rotations into a single output via a second differential. Yes, I did test this out, and it works. However... Read more

When Mark Longenberger graduates on Saturday, May 9, he will have earned both a bachelor’s degree in mechanical engineering from Penn State Berks and a master’s degree in applied statistics from Penn State World Campus. The master’s degree is an integrative undergraduate-graduate degree program, which allowed him to complete course work for both degrees concurrently. He also minored in both mathe…

Argonne National Laboratory debuts the Heavy-Duty Dynamometer Test Facility, a national resource to speed technology development and strengthen U.S. freight competitiveness.

A practical Mechanical Systems and Signal Processing (MSSP) submission guide for mechanical engineering researchers evaluating their work against the journal's signal-processing bar.

I spent the last month building a power meter for sledgehammer strikes: a pad you hit that tells you how hard you hit it, and whether you can do it again tomorrow. This is the founder story: what I built, why I chose it, and what a month of hardware taught me. The engineering writeup will come later, once I've talked to someone who actually understands IP strategy. For now, the public home for th…
