A homework question about Acoustics-Mechanical Engineering.
crystalletterA spring-mass-damper system is driven by a triangular wave forcing function as described by the equation: PLEASE SEE THE IMAGE in attachment, where PLEASE SEE THE IMAGE in attachment:
See the waveform sketch below. Hint: You know the frequency-dependent mechanical impedance of a mass-spring-damper system, and you know that superposition applies.
(a.) Find the real-valued velocity response v(t) = dx/dt.
(b.) Is the output v(t) also a triangular wave? Explain briefly.
(c.) What is the mean square velocity v^2.
(d.) Find the average power W dissipated per cycle.
