Q2 Figure Q2 shows the schematic diagram of wind turbine which used in power plant. By using the exact solution method, it is found that the fundamental natural frequency for the system is wh = 0.6Vkt] rad/s. Assume that Ji =J2 = J, and ki = k2 = k. (a) Establish the free body diagram and equation of motion in the matrix form for gear box, generator, low-speed shaft and high-speed shaft. (b) By using standard matrix iteration approximation method, determine the lowest natural frequency in Hertz unit and its corresponding mode shape for Q2(a) answer if the initial trial vector is -0.1 Use J= 2, and k:= 5, and show up 2.9 to four (4) iterations calculation.
