m \ddot{x}+c \dot{x}+k x=f

The dependent variable 'x' represents displacement of the mass 'm'. The value of 'm', along with those of the specified undamped natural frequency on and damping ratio Ç are provided in the datasheet. Calculate the:

(a) Required values of c and k in Sl units

(b) Gain (dB) of the force-to-displacement transfer function x(s)/f(s) at angular (radian)frequencies o of 0.1, 1.0 and 10 times on.

The initial conditions are y(0)=0 and y(0)=1. Based on the values of a, b, c, and T specified in the data sheet, calculate the

a \ddot{y}+b \dot{y}+c y=0

(a) poles;

(b) value of y(T).

(a) value of R (2) required to achieve the time constant t, which, together with L, is specified 5in the data sheet.

(b) Gain (dB) and phase (deg) of the transfer function vout/Vin at radian frequencies 0, such that OT = 0.1, 1.0, and 10.
