If you mean a point where a torque is applied by string tension, then in 2d there's only one, the centroid of the cross section of the top and braces where it intersectects the plane of the saddle. I 3d it's more complex. In either case, the string tension beyond the saddle contribute to the internal stresses of a rigid bridge/top/plate structure, and not to the torque on that structure.
