ABSTRACT:
A slat rotatably supported at its ends has its mass center offset from the axis due to sag. A spring biased mass is attached to the slat for creating a torque when the slat is rotated which counterbalances the torque created by the offset slat mass center to minimize the drive force required to rotate the slat.
