If you’re lucky enough to have your mother around this time of year, you’re probably scrolling through endless pages of ad covered Mother’s Day gift idea blogs searching for that one thing that expresses a year’s worth of love and appreciation, but also doesn’t cost more than 100 bucks. But I’m going to remind you… Continue reading Segmented Vases for Mother-s Day
Speaker 1: Despite its excellent qualities as a structural material, concrete has weaknesses to one that we’ve discussed in previous videos is that it has almost no strength against tension. Concrete can withstand a tremendous amount of compressive stress, but when you try to pull it apart, it gives up easily. Concrete’s other weakness is… Continue reading What is Prestressed Concrete?
Speaker 1: A surprising amount of engineering is just avoiding conflicts. I’m not talking about arguments in the office. I mean conflicts when two or more things need to be in the same place. Speaker 2: There are a lot of challenges in getting facilities over under, around in between each other. And there’s a… Continue reading What Is a Culvert?
The dam didn’t fail, but it came too close for comfort, especially for the tallest structure of its kind in the United States. Auroville Dam falls under the purview of the Federal Energy Regulatory Commission in a state with a progressive dam safety program and regular inspections and evaluations by the most competent engineers in… Continue reading What Really Happened at the Oroville Dam Spillway?
If you subject a fluid to a sudden change in pressure, some interesting things can happen. You can cause tremendous damage to moving parts, but you can also harness that destructive power for many beneficial uses from mantis shrimp killing their prey to ultrasonic cleaning. So many things rely on this fluid phenomenon. You may… Continue reading What is Cavitation? (with AvE)
We humans are fascinated with the coast, it’s not just that the sea facilitates commerce and travel, it’s not only because it’s fun to swim in the water and lie in the sun on the beach. There’s something inherently interesting about seeing the place where two things meet, where the vast expanse of ocean touches… Continue reading How Coastal Erosion Works
One of the most important considerations when you build anything is the material, it impacts everything from the look and feel to the more fundamental characteristics like weight and strength. But maybe the most significant aspect of a construction material is its cost. Infrastructure is not made to be glamorous, and it’s often paid for… Continue reading Sand Castle Holds Up A Car! – Mechanically Stabilized Earth
I got something fancy for Christmas this year, this is my new BTIG welding machine, which I’ve already christened in typical practical engineering fashion. I’m a welding newbie and currently absorbing anything I can on the subject. So while I learn, I thought I would take the time to boil down some of that new… Continue reading Welding 101 for Hobbyists (and Nerds)
This is the magnitude hydropower plant on the Montreal River in eastern Ontario, Canada. It doesn’t look like much from an aerial photo, but that’s because the most interesting parts of this facility are underground, two massive vertical shafts and a large tunnel connecting the two before it was converted to generate electricity. Ragged Chute… Continue reading Compress Air with No Moving Parts
Controlling the flow of water is one of the fundamental objectives of modern infrastructure, from flooding rivers to irrigation canals, stormwater drainage facilities to aqueducts and even the spillways of dams. So engineers need to be able to predict how water will behave in order to design structures that manage or control it. And fluids… Continue reading What is a Hydraulic Jump?
