Why it works
The 0:00 spotlighted fastener creates curiosity, then the 0:49–1:22 cutaway shows bolt stretch before naming preload. The most-replayed passage at 2:30.9–2:41.7 animates the split between bolt load and clamping force with changing figures; a spring analogy at 2:59 gives viewers a simpler model. The automated one-shot count is visibly unreliable for this animated excerpt.
