A torque arm, for a dynamometer defining an axis of rotation, having a first, support, end configured for rigid attachment of the arm to the dynamometer, a second, free, end for engaging a reaction stop, a longitudinal axis, an axis intersecting and perpendicular to the longitudinal axis, the axes intersecting and being perpendicular to the axis of rotation when the arm is attached to the dynamometer and a strain gauge for measuring strain of the arm on the transverse axis whereby the strain measurement is a function of torque applied to the arm by an attached dynamometer about an axis of rotation independent of the distance between the axis of rotation and a reaction stop engaging the second end. A dynamometer assembly comprising a dynamometer and such a torque arm attached to a housing of the dynamometer.
