Why it works
The I-beam grows into view in the first second, with green loads and yellow reactions added by 2–3 seconds, so the lesson begins with a concrete object. Stable colors make invisible forces legible around 0:43–1:05, and the most-replayed analysed span, 5:44–5:54, turns a bending sign convention into an immediately recognizable sagging shape. The source extends beyond the six-minute analysed excerpt.
