A force exerting device having a force exerting structure including a load arm as a first side, pivotable about a load pivot, a resilient member attached to the load arm and to a termination point and forming a second side of the force exerting structure. The third side of the structure is formed by a line from the termination point to the load pivot. A first adjustment mechanism moves the termination point to change the length of the third side of the structure. A second adjustment mechanism moves the termination point in a direction different than the first adjustment direction so the termination point location can cross a substantially plumb line passing through the load pivot. A force modification device may be included to dynamically adjust the resilient member termination point position in response to motion of the load arm.
