There’s a lot changing in the construction industry, and a lot of growth in the need for materials like sand and gravel. But I don’t think it’s fair to say the world is running out of those materials. We’re just more aware of all the costs involved in procuring them, and hopefully taking more account for how they affect our future and the environment.

Digital systems interact with every aspect of our daily lives and basic needs: water, electricity, sanitation, public health, transportation, and more can all be seriously disrupted by someone or some group, anywhere in the world, if we let our guard down. With great computer power comes great computer responsibility. And just because many of these industrial control systems are only used or understood by a small number of people, security through obscurity just isn’t realistic anymore.

Correction: Tyler is west of New London, not east.
Natural gas is one of the most important resources on the planet right now. It’s driven countless innovations that benefit nearly everyone in a huge variety of ways. And so, even if you had never heard of New London, Texas before now, you can feel fairly confident that, all these decades later, you’ve also benefited in some way from the hard lessons learned there in 1937.

This is a crazy case study of how common sense can fall through the cracks of strained budgets and rigid oversight from federal, state, and city staff. And the lessons that came out of it aren’t just relevant to people who work on bridges. It's a story of how numerous small mistakes by individuals can collectively lead to a tragedy.

Without listing every bridge, there’s no true way to list every type of bridge. There’s too much nuance, creativity, and mixing and matching designs. But that’s part of the joy of paying attention to bridges. Once you understand the basics, you can start to puzzle out the more interesting details.

All of our lives benefit in some way from this enormous control over Earth’s freshwater resources. But those benefits come at a cost, and the price isn’t just the dollars we’ve spent on the infrastructure but also the impacts dams have on the environment. This kind of balancing act is really at the heart of what a lot of engineering is all about.

A single modern diesel freight locomotive can deliver upwards of 50 tons of forward force (called tractive effort) into the rails, but it’s somehow able to do that through the tiny contact patches between two smooth and rigid surfaces. It’s just slick on slick.

It is a challenging endeavor to put any tunnel below the sea, and this monumental project faced some monumental hurdles. From complex cretaceous geology, to managing air pressure, water pressure, and even financial pressure, there are so many technical details I think are so interesting about this project.

The lean isn’t just a fascinating oddity; it is integral to the historical character of the tower. It’s a big part of why we care. Unlike the millions of photos of tourists pretending to hold the Pisa tower up, the contractors, restoration experts, and engineers actually did it (for the next few centuries, at least).

Errata: At 9:00, the left column of calculations is incorrectly labeled "SI." It should be imperial. Whoops!
Just as all materials have a mostly linear relationship between temperature change and length change, all materials also have a similar relationship between stress and change in length (often called strain). And this is part of the secret to continuous welded rail: restrained thermal expansion. You can overcome one with the other.

Comparing costs and safety is an enormous challenge. On one side, you have dollars, and on the other, you have people. Sometimes you need a conversion factor. It sounds morbid, but it’s necessary for good decision-making to put a dollar price on the value of a human life.

Errata: At 6:52, the graphic should show the dimension of the wheel's diameter (not radius).
In the 19th century, railway engineering was all about how to build railroads. Modern rail engineering focuses on getting the most out of the system. It might not look like much when you see a train passing by, but a huge amount of research, testing, and engineering went into the shape of those rails and wheels.

One statistician famously said, “All models are wrong, but some are useful.” And even something as simple as the flow of water into the soil has so many complexities to keep track of. Like most answers to simple questions in engineering and in life: the answer is that it’s complicated.

It takes a lot of big tools to build the roads, dams, sewage lift stations, and every other part of the constructed environment. To me, there’s almost nothing more fun than watching something get built, and that’s made all the better when you know what all those machines do.

Errata:
At 10:40, the meter is set to resistance (not voltage). Since current is constant, it is also an indication of differences in voltage, but the script should have been a little clearer.
Current doesn’t flow to the ground; it flows through the ground and back up. If there is electricity moving into the ground from an energized conductor, go back to the source of that conductor and see what’s happening. For the grid, it’s probably a transformer or electrical generator, in either case, a simple coil of wire. And, the electrical current flowing out of the coil has to be equal to the electrical current flowing into it, whether that current is coming from one of the other phases, a neutral line, or an electrode buried in the ground.

Tanker truck fires at bridges happen rarely, but when they do, they often lead to a collapse or at least a replacement. How do engineers characterize bridge fires, and should bridges be better protected against them?

Correction: The Carlsbad plant produces 50 MGD, which is roughly 190,000 cubic meters per day (not 23,000 as stated).
It might surprise you to learn that there are more than 18,000 desalination plants operating across the globe. But, those plants provide less than a percent of global water needs even though they consume a quarter of all the energy used by the water industry. The oceans are a nearly unlimited resource of water with this seemingly trivial caveat, which is that the water is just a little bit salty. It’s totally understandable to wonder why that little bit of salt is such an enormous obstacle.

Unlike NASA, which spends years in planning and engineering, SpaceX uses rapid development cycles and full-scale tests to work toward its eventual goals. They push their hardware to the limit to learn as much as possible, and we get to follow along. They’re betting it will pay off to develop fast instead of carefully. This video compares the Stage 0 launch pad to the historic pad 39A.

On September 13, 2018, a pipeline crew in the Merrimack Valley in Massachusetts was hard at work replacing an aging cast iron natural gas line with a new polyethylene pipe. By the end of the day, over a hundred structures would be damaged by fire and explosions, several homes would be completely destroyed, 22 people (including three firefighters) would be injured, and one person would be dead.

It turns out that plenty of types of infrastructure, especially those that have serious implications for public safety, are equipped with instruments to track their performance over time and even save lives by providing an early warning if something is going wrong. Engineers keep an eye on strain, vibrations, temperature, pressure, tilt, flow rate, and more to make sure that structures behave like they were designed and to keep people safe from disaster.

On the evening of Friday, February 3, 2023, 38 of 149 cars of a Norfolk Southern Railway freight train derailed in East Palestine, Ohio. Five of the derailed cars were carrying vinyl chloride, a hazardous material that built up pressure in the resulting fires, eventually leading Norfolk Southern to vent and burn it in a bid to prevent an explosion. The ensuing fireball and cloud brought the normally unseen process of hazardous cargo transportation into a single chilling view, and the event became a lightning rod of controversy over rail industry regulations, federal involvement in chemical spills, and much more.

Last August, a flood took out the aging water system in Jackson, Mississippi, leaving nearly everyone in the City without water. Only a few months later, arctic weather broke so many pipes in the city that residents again lost access to water, some for nearly two weeks, continuing one of the worst water crises in American history.

This event highlights the need for making critical substations more secure and also making the grid more robust so that someone can’t rob tens of thousands of people of their lights, heat, comfort, and livelihood for four days with just a few well-placed bullets.

Watch on Nebula: nebula.tv/videos/practical-engineering-how-different-spillway-gates-work
Almost all dams need a way to release excess water when the reservoir is full. Although many dams use uncontrolled spillways, gated spillways provide more control over the flow, allowing us to build smaller, more cost-effective structures. There are countless arrangements of mechanical devices that have been used across the world and throughout history to manage the flow of water. But, modern engineering has coalesced to variations on only a few different kinds of gates.

Errata: (None yet)
Both Florida DOT and Superior Construction were contacted for comment on this story. FDOT declined to comment, and Superior Construction did not respond to multiple emails.
Barrier islands are critical to protecting mainland coasts by absorbing wave energy and bearing the brunt of storms. But development on the islands negates that critical purpose. That doesn’t mean the community doesn’t belong there. But it does obligate the planners and engineers involved in rebuilding to be thoughtful about the impacts hurricanes can have and how infrastructure can be made more resilient to them in the future.
