A strain-gage torquemeter employing a circuit to minimize effects of contact resistance was constructed and the performance under static and dynamic conditions was investigated. Dynamic tests of this instrument were made over a range of shaft speed form 500 to 17,000 rpm and torque loads from 250 to 5500 inch-pounds with corresponding torsion shaft stresses of 600 to 14,200 pounds per square inch.
