FEATURED TESTIMONIAL – “Dr. Tom’s Explanations Were Invaluable”
“I purchased Dr. Tom’s Mechanical Thermal and Fluid Systems review course due to the positive feedback it had received from various engineering message boards. I was especially encouraged by the free videos accessible from Dr. Tom’s YouTube channel. As I worked through the course, I found that Dr. Tom was able to clearly and succinctly […]
New York a Step Closer to Using Drones to Inspect Buildings
New York City has thousands of buildings and many of them are old and have issues with the facades falling apart with age. Two years ago a woman was killed by a falling piece of debris from a building. Detailed inspections often require expensive scaffolding that ties up sidewalk space and is unsightly. The solution, […]
Attention Mechanical Engineers! It’s Time to Get Your PE

Living Walls can Reduce Heat Loss from Buildings by 30%
Researchers at the University of Plymouth in England are studying how utilizing living walls can reduce heating and cooling costs in older buildings. A pre-1970’s building (called the Sustainability Hub) on campus was retrofitted with flexible fabric sheet systems with pockets allowing for soil and planting. After 5 weeks of measurements, the heat loss in […]
Deep into the Sea and the Imagination
I grew up watching the TV series “Sea Hunt” staring Lloyd Bridges. The lead character had been a former Navy frogman, what is now called Navy Seals. With his sophisticated scuba gear he seemed to be able to go anywhere under the water. What I would come to learn in my fluid mechanics classes is that […]
Russian City Is Cooling Ground to Preserve Buildings
Norilsk, a city of 170,000 in northern Russia, is mechanically cooling the ground in places to prevent the permafrost from melting. When the permafrost melts, the ground becomes soft and large buildings (like apartment blocks) will sink or tilt. So, about 8 million Euros are being spent to thermally stabilize the ground. This issue is […]
The Mothership – Science Non-Fiction
I think the first time I heard the term “mothership” was in the sci-fi movie “Independence Day.” The term is now commonly used to reference a space ship that can deploy and recover smaller versions of itself. However, up until now this concept was only science fiction. Well, according to a recent Breaking Defense article, DARPA, […]
A Sincere Thank You to Veterans
On Veterans Day, everyone here at Dr. Tom’s Classroom would like to thank all veterans for their service to our country. We appreciate their dedication and contribution to preserving our freedom. We especially honor the many engineers who have served in the United States military. Their work is an inspiration to us all. U.S. Military […]
Rollover Alleys – The Dynamics for Disaster
Vehicle dynamics are an important consideration for highway design and construction. Large trucks are a common design vehicle for highway infrastructure. A variety of factors focused on large truck characteristics include: turning radius at intersections/driveways, lane widths, acceleration on upgrades, control of speed on downgrades, and more. Due to the high center of gravity (which can be exacerbated by […]
Flying into the Future
Having a BS degree in Aerospace Engineering, a recent ASME article titled, “5 Aerospace Technologies and Trends,” caught my eye. Noting the 5 technologies and trends identified in the article, it was clear that this article was important to mechanical engineers as well. In fact, I believe these technologies and trends will affect the entire engineering community. I […]
