QUESTION 1 15.00000 points The mechanical system shown in the figure below is excited by a sinusoidal force f -Fi cos at + ?:) N. The differential equation of the displacement xt) is Md2xidt2 + D dx/dt + Kx=1(t) Use phasor techniques to solve for the displacement phasor Xin terms of the excitation frequency w, and the mechanical elements M 0.1 kg. D = 8 N-sim , and K = 2,000 N/m . If Fi 10 N and Di = 30., determine the excitation frequency ? (in radis) at which the displacement magnitude |XI is maximum.
