This is a genuine worked-problem video from a tiny channel (27 subscribers) that tackles Problem 4-1 from Reinforced Concrete: Mechanics and Design, 8th Edition — a well-known textbook by Wight and MacGregor used in graduate structural engineering courses. What makes this worth watching is the specific reference to ACI 318-25, the newly-updated American Concrete Institute code. Anyone doing reinforced concrete design has to keep up with code revisions, and seeing a full analysis reworked against the current standard is genuinely useful.

The video walks through analyzing a simply-supported RC beam: computing the nominal moment capacity, checking whether the section is tension-controlled or compression-controlled, applying the correct strength reduction factor (φ), and comparing against factored loads. These are the fundamental checks every structural engineer performs, but the details matter — strain compatibility assumptions, the equivalent rectangular stress block, minimum and maximum steel ratios, and the ductility requirements all interact in subtle ways.

The other candidates were mostly shorts, live-stream fragments, or introductory lectures. This one shows an actual engineer doing an actual calculation with an actual code reference — the kind of thing you'd see on a real design desk. If you're a civil engineering student or a practicing engineer refreshing on ACI updates, it's a solid 30-minute investment.
