A particular strain sensor is mounted to an aircraft wing that is subjected to periodic wind gusts. The strain measurement system indicates a periodic strain that ranges from 3250 x 10⁻⁶ in./in. to 4150 x 10⁻⁶ in./in. at a frequency of 1Hz.

(a) Determine the average value of this signal.
(b) Determine the amplitude and the frequency of this output signal when expressed as a simple periodic function.
(c) Determine a one-term Fourier series that represents this signal.
(d) Construct an amplitude spectrum plot for the output signal.

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.
