ABSTRACT:
A system for measuring a force applied to a mass so that the magnitude and direction of the force can be determined as well as the torque about three orthogonal axes. The system comprises an electromagnetic bearing support system for electromagnetically suspending the mass in a predetermined position and orientation relative to a three-dimensional coordinate system defining three mutually perpendicular axes. The forces applied to the mass are measured by measuring the force components of each applied force along one of the axes so that the one axis defines a reference axis. The force components in the direction of the two remaining force components are each measured at two locations along the reference axis. The roll of the mass about the reference axis is measured and the yaw and pitch of the mass about the two remaining axes is determined as a function of the two components in the direction of the of each of the two remaining axes.
