Original text. Later amendments are not shown.

  1. 3.1.1The free oscillation of the sprung mass shall be given by the following equation:
  2. 3.1.2The frequency of oscillation (‘F’ in Hz) of the sprung mass shall be given by the following equation:
  3. 3.1.3The damping is critical when C = Co
  4. 3.1.4Division 3.1.4
  5. 3.1.5If the peak amplitudes of the first and second cycles of the oscillation are A 1 and A2, then the damping ratio D is given by the following equation:
