I’m looking for a book (preferably eBook) which explains one or more engineering projects in great detail....
Roof sections of the Sydney Opera House (sh.itjust.works)
The original design of the Sydney opera house featured roof sections with unique curves. This caused two major problems: (1) the structural analysis was very difficult, and (2) it made construction more expensive since they could not reuse construction details among the roof sections. Eventually the engineers realized they could...

Ejection seats (pic 1) (i.imgur.com)
A post on NCD sent me down a rabbit hole reading about ejection seats. Do we have anyone here who can share some first-hand knowledge about the designs? I didn’t fully appreciate these products before: thousands of parts, multiple precisely timed pyrotechnic charges, and big consequences for failure. That sounds like a very...

Posting a second picture that shows and earlier stage in the process. Multiple charges ignite to remove the canopy from a CF-18 Hornet immediately before the pilot ejects. Photo from ejectionsite.com, which has more info on the incident.

How a basic automotive thermostat works (i.kinja-img.com)
The valve core contains a specially designed wax. The wax expands as it is heated, forcing the valve open and allowing engine coolant to flow to the radiator. When the wax cools and contracts the valve is closed by a return spring....
Engineering for hikers (sh.itjust.works)
I wonder how many people understand the planning and work that goes into making hiking trails and shelters for us weekend warriors. For example, here’s a sample trail project package following the US Forest Service’s standard plans and specifications. A trail is so much more than a strip of bare ground....

Just let the TBMs keep going. (www.reddit.com)
I had an idea a little while ago that tunnel boring machines should just keep going. Think of all the tunnel we could have if all the TBMs just never stopped. We could have an ever growing tunnel network that could be tapped into as needed.
A Whale-Oiled Machine - 99% Invisible (99percentinvisible.org)
This 99% Invisible podcast touches on the history of mechanical lubrication, from vegetable oils to whale blubber to modern synthetics. Featuring Bill Nye the Science Guy, who is apparently a direct descendant of William Foster Nye, the founder the Nye Lubricants.
