ABSTRACT:
A torque measuring apparatus having a head adapted to rotate about an axis of rotation and a lever arm extending from the head and perpendicular to the axis of rotation designed to react to normal forces applied at a distance from the head. On the lever arm are a plurality of strain transducers spaced apart a certain distance as determined in accordance with predetermined mechanical properties of the lever arm. The transducers are joined electrically to form a bridge circuit, the output of which is directly proportional to the torque on the workpiece. This output is then transmitted to a display for a visual presentation of the torque.
