1) A certain strain sensor is mounted on an aircraft wing that is subject to periodic wing gusts. The sensor is attached to a measurement system that indicates that the strain can be approximated by a sinusoidal function (i. e. sine wave) ranging from 3560 x 10-6 cm/cm to 5216 x 10-6 cm/cm at a frequency of 3 Hz. At a second flight condition, the strain had an additional sinusoidal component (i. e., in addition to the first sinusoid above) that has twice the above frequency, half of the magnitudes, and 90 degrees out of phase (leading). Determine:a) The average strain value for the 1st and the additional sinusoidal functions, separately. b) The oscillating amplitude for the 1st and the additional sinusoidal functions, separately. c) Write the Fourier transform for the strain signal for both flight conditions, separately. d) Show a diagram of the amplitude spectrum for the sensor signal, for both flight conditions separately.

An external consultant recommends that a plant installs a bank of capacitors for power factor correction. this will reduce the peak electrical demand charges by an average of 93 kw every month. the plant current pays $13 per kw in peak demand charges. the capacitor bank will include 223 kw of fixed capacitors, and 183 of variable capacitors. the fixed capacitors cost $59 per kw, and the variable capacitors will cost $65 per kw. the consultant charges 21% of the equipment costs to install the capacitors. because this project will reduce the demand for the electric utility, they are prepared to provide a one-time rebate of $42 per kw of reduced demand. what is the simple payback period for this project (in years)?
