Ladder Forces (1K10.20)

Description:

A model ladder is positioned as though it were leaning against a wall, but is actually supported by three spring scales that provide the horizontal "wall" force and the horizontal and vertical "floor" forces needed to keep the ladder in equilibrium. A weight can be hung from various rungs of the ladder to vary the forces, which are read directly off the scales.

Procedure or Operation Notes:

Ladder: 4.7 N.

Hanging Weight: 14.5 N.
