ANS:
There are two examples of real-world applications of con- centricity or symmetry tolerances on a drawing. The first application is using concentricity to limit the deviations of median points relative to a datum axis or center plane for balance of a high-speed rotating part (equal distribution of mass of a turbine or flywheel). The second application is using symmetry to control oscillating motions (e.g., a tuning fork or pendulum).
