An uncaptioned plot shows the shock response spectra which will be
used in sine vibration testing.  The abscissa is representing the
range of frequencies that will be swept through.  The range of data
is between 1 and 1000 Hertz.  The ordinate represents the equivalent
sine amplitudes for the range of frequencies.  The range of data on
the ordinate is from 0.1 to 10 g.  Two plots are shown in the figure.
The plots are within 5 and 200 frequency range.  Each plot consists of
three segments.  The first segment is between 5 and 10 Hertz, the
second segment is between 10 and 130 Hertz, and the third segment is
between 130 and 200 Hertz.  The amplitude of the first segment increases
linearly and reaches 1.0 g.  The second segment has constant amplitude
at 1.0 g, and the amplitude of the third segment increases linearly to
20 Hertz.  This plot is labeled “FA”.  The second plot is identical to
the first one; however, the entire plot is shifted up by approximately
0.6 g.  This plot is labeled “TA”.  The frequency sweep rate for FA is
two octaves per minute.  The sweep rate for TA is four octaves per minute.
