A continuous congruent length of stranded flexible Drilling Energy Transfer Member (DETM) to transfer and balance action/reaction forces between an energy source and a working tip (9) such that torque, tensile, compression and self supporting forces are constrained while the DETM operates in multiple positions of tight curvature and straight run. The DETM having a core load cell with a plurality of strands (13, 14, 16) sized and layered at a helical angle and an outer wrap load cell with a second plurality of strands (17, 18) sized and layered at a helical angle. |
