Abstract:
Methods of force management for a force management anchor (FMA) include apparatus between a post and a base plate that resist post rotation under fall loads, the apparatus resisting said rotation at a constant torque. A peak constant torque is less than a torsional “tear-out” capacity of a surface for maximizing energy absorption. While the fall force vector remains generally parallel to the base plate during a fall, the post is movable between an upstanding and a lowered orientation resulting in a variable moment arm and a resisting force that also varies for maintaining the torque substantially constant. Apparatus can include devices between the post and the base plate such as a torsion rod, a friction clutch or a cam arrangement. Other approached include designed deformation of the post itself, such as a through tapered post.
