Experimental setup for testing of RS with 0- and 10-Nmm force-moment. The moment was induced by a lever arm of 10 mm and a lead weight of 100 g. The center of rotation was placed within the bracket (a) and 10 mm from the bracket (b). Configuration “a,” without the lead, was used for testing without an applied moment. For all setups, the wire was attached to a stainless-steel chain, which was found to be essential in order to eliminate all undesired RS from torque or minimal malalignment.
