Chap. 9 Problems 327 Sliding mass F,(t) Friction coefficient B Guide track T/2 Figure 9.39: A machine drive and the force driving waveform. where the as are constant coefficients. Determine the undamped natural frequency and the damping ratio in terms of the system parameters, and rewrite the equation in terms of the undamped natural frequency and damping ratio. If the output variable y(t) s a displacement, what are the appropriate units for the constant coefficients in (i) the SI system and (ii) the English system of units?
