Why Expandable Dining Tables Fail: Center Sag, Leaf Alignment & Extension Mechanism Engineering

Expandable dining tables fail at the center because the leaf seam interrupts the load path, creating structural discontinuity, tolerance stacking, and mid-span sag. This engineering breakdown explains why leaf misalignment, gaps, and racking are predictable outcomes—and what internal features (apron depth, synchronized slides, center stretchers) actually prevent failure.
