$9\mathrm{.}28$ A sinusoidal force acts on the mechanical system illustrated in Figure $9\mathrm{.}49.$ Considering that $m=0\mathrm{.}6kg$ and $k=220\frac{N}{m},$ analyze the transmissibility of the input force to the force on the wall for $c_1=10N\frac{s}{m}$ and then for $c_2=15N\frac{s}{m}$ during the steady$-$state regime.

$(1)$ Make Bode Plot for Magnitude $($absolute value$)$ in MATLAB by adding: opts.MagUnits $=$ 'abs';

$(2)$ Include your name in the title by adding: opts.Title.String $=$ 'your name Bode Plot';
