The oscillating motion of lever 1 is converted into recipicrocation of slider 2. The spherical end of lever 1 slides along vertical guides of the upright. Displacements x and y of po ts A and B are related by the equation y=sqrt(A͞͞B²-x²). The angle a of rotation of lever 1 equals α=arcsin(x/A͞͞B).
