External force can be exerted from one or more weights placed on top of the bending sleeve assembly. External force can be exerted from a winch attached to a wire, the wire passing through a pulley attached to a fixed structure, and the wire attached to the bending sleeve assembly. External force can be exerted through the bending sleeve assembly's contact reaction with an immobile object. | 12-30-2010 |
