The lengths of the links comply with the conditions: A͞B=B͞C=A͞D=D͞O=b and D͞K=a. Link 2 turns about fixed axis A and is connected by turning pair B to link 3. Slot d of link 4 slides along a pin at point B. Slider 1 is connected by turning pair C to link 3 and moves along fixed guide e. Slotted link 4 turns about fixed axis D and its pin K slides in slot h of link 5 which slides in fixed guide q. The mechanism is intended for the mathematical operation y=(a/2b²)sqrt(z) where z = distance of point C of slider 1 from fixed point 0, y = distance from axis of slot h of link 5 to point D, a and b = constant dimensions of the mechanism.
