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 disk 2 to the axis of pin 5, and by the angle of rotation of disk 1. The setting is made with pin 5 which slides along spiral slot d of disk 1 and along radial slot a of disk 2. Slot d is in the shape of an Archimedean spiral. The magnitude and angle of inclination of the vector to be resolved are entered into the mechanism by means of gears 4 and 1, planet bevel gear 8, and gears 9 and 10, which are turned by handwheels 3.
