This 3-shot method requires displacement of 3 positions at 0,120,240 degrees and initial displacement to determine the position and magnitude of mass to be placed for balancing disks/shafts. The advantage of 3-shot method over 2-shot method is that it requires knowledge of displacement amplitude only while the 2-shot method requires the knowledge of both displacement amplitude and angle of the unbalance. The program locates the centroid of the area by approximating it as a triangle if the three circles intersects each other other wise it calculates the centroid of the triangle formed by the external tangents of circles.
