Engineers: Stress and Pressure at Work

Engineers have a tough life. I mean what other profession has to deal with stress, pressure and strain? It sounds like engineers have a lot in common with mental health professionals. If you are a fluids engineer like I am, then strain itself is not enough. What matters is how fast the strain happens (the rate of strain). This affects the viscosity...

Fluid Mechanics 101 – The Class That Changed My Life

I was 20 years old and 18 months away from finishing my formal education. Forever. I was well on my way to being a… structural engineer. Wait, that must be a typo. Structural? Really? Where did the fluids come in? I really liked structural mechanics and that was where I was focused for the first 2.5 years of my mechanical engineering studies. My cl...

A Space Shuttle Trifecta Achieved Today

​It was not intentional. The Trifecta I mean. It just sort of happened organically. But now that I have completed it, I think it is kind of cool. There are three Space Shuttles that have flown into space and are now in American museums: Discovery - in the Smithsonian Air & Space Museum  in Chantilly, Virginia (near Washington D.C...

When a Lowly Engineering Student Ends Up Working With One of His Exalted Professors

Gary Vanderplaats was one of my (exalted) professors in 1985 when I was a (lowly) Senior engineering student at UCSB. If not for Gary, there would be no GSC modules for AFT Fathom or AFT Arrow , and no new AFT Fathom ANS module either. Why? First, back in 1985 UCSB had a required course for ME students in Design Optimization. It was probably one of...
