The mechanism is intended for resolving a vector along coordinate axes in the plane of action of the vector. The translational displacements of slides 6 and 7 are proportional to the components along the coordinate axes of a vector preset by the distance from the centre of pinion 9 to the axis of pin 5, and by the angle of rotation of disk 1. The setting is made with pin 5 located at the end of rack 4 which meshes with pinion 9. The magnitude of the vector to be resolved is entered into the mechanism by means of shaft 8 which is rigidly attached to the carrier of planet bevel gears b and b₁. The angle of inclination of the vector to the coordinate axes is entered by turning disk 1 from shaft 3 through pinion 10 and the teeth on disk 1. The rolling of rack 4 about pinion 9 distorts the magnitude of the vector. This is eliminated by the provision of gears 11 and 12, and cluster spur and bevel gear 13 which rotate pinion 9 through planet gears b and b₁ and bevel gear 2.
