The above stress can be also approximated by a sinusoidal function (i. e. sine wave) with an average 3,811 kPa, amplitude 430 kPa, and a frequency of 6 Hz. At a second flight condition, the stress had an additional sinusoidal component (i. e., in addition to the first sine wave above). This second component is caused by half the amount of forces (relative to the first condition), has three times the frequency, and 90 degrees out of phase (leading). Determine the average of the second sinusoidal component in kPa. (Provide the answer using 2 decimal places).
