Figure shows the block diagram of a wideband frequency modulator using the indirect method. This modulator is used to transmit audio signals containing frequencies in the range of 100 Hz to 15 kHz. The narrowband phase modulator is supplied with a carrier of frequency f1 = 0.1 MHz by a crystal-controlled oscillator. A second crystal. controlled oscillator student submitted image, transcription available below a question and you will be sure to find an answer!

Question
Consider the heaving motion of a 500 ft ship traveling at 15 knots at a heading of μ = 160°. For a sea state with a significant wave height of 5 m and a modal period of 10.8 sec, the variance of the heave motion was 1.33 m, the variance of the heave velocity was 0.581 m2 /sec2, and the variance of the heave acceleration was 0.293 m2 /sec4. Find the significant heaving magnitude and the probability of the heaving motion exceeding 2.8 m.

Question
solid constant-diameter shaft is subjected to the torques shown in Figure. The bearings shown allow the shaft to turn freely. (a) Plot a torque diagram showing the internal torque in segments 1, 2 and 3 of the shaft. Use the sign convention. (b) If a solid 1.905 cm diameter shaft is subjected to that particular torque. Determine the maximum shear stress magnitude in the shaft. (c) If the allowable shear stress in the shaft is 80 MPa, determine the minimum acceptable diameter for the shaft.
