Remember the story of Archimedes saying that he could lift the Earth with small force but long enough lever? Now imagine a nut on the jet engine which is requiring torqueing with a torque wrench capable of 16700 Nm (or 12000 lb fts) torque. This is the same if you would apply a 1kg on 1,6 km lever or 1 pound force on the lever of 2,27 miles. We made a precise tool adapter for torqueing the special nut on the engine capable of transmitting this torque. Archimedes would be proud!
