The square shaft is used at the end of a drive cable in order to register the rotation of the cable on a gauge. If it has the dimensions shown and is subjected to a torque of 8 N⋅ m, determine the shear stress in the shaft at point A. Sketch the shear stress on a volume element located at this point.
