Consider the mechanical system shown to the right. Assume that m= 1kg , b=3N•s/m, and k = 50 N/m. Note: The displacement x is measured from the equilibrium position before the force f(t) is applied. = k b f(t) Considering a sinusoidal input f(t)= F, sin ot , which of the following is the Bode diagram for the transfer function G(s)= X(s)/F(s)? Note that the axes are different for each plot. = m w x k 0.
0. Bode Diagram Magnitude (dB) -40 -60 -80 0 -45 Phase (deg) -90 - 135 -180 10-1 10° 101 Frequency (rad/s)
O. Bode Diagram 20 Magnitude (dB) -20 -40 0 -45 Phase (deg) -90 -135 -180 100 102 101 Frequency (rad/s)
Bode Diagram -20 Magnitude (dB) -40 -60 -80 0 -45 Phase (deg) -90 - 135 -180 10-2 10-1 100 101 102 Frequency (rad/s)
Bode Diagram -20 -40 Magnitude (dB) -60 -80 0 -45 Phase (deg) -90 -135 -180 100 101 102 Frequency (rad/s)
