EXAMPLE
Project a line from the efficiency required on the right -hand side to intersect the performance lines 1008, 1006 and 1004. Project those intersections down to obtain the two dimensionless ratios (R) for the three mountings. Divide the lowest running speed (Hz) of the complete machine by R to give the natural frequency f'n required. Compare f'n with the actual natural frequency (fn) of the mounting concerned . If f'n fits into the fn band of the mounting, select that mounting. If two mountings meet the above conditions, select the one with higher fn; it will be more stable.
