Fulcrum Beam

Show balancing moments with coins and clips

A 249 mm balance beam whose central bridge arch sits on the Fulcrum Stand tip, 18 mm above the beam line so it always swings back level. Eight V notches at matched distances hold paper clips loaded with coins: put two coins at 32 mm and one at 64 mm on the other side and watch the moments cancel.
