harmonic oscillator:

using matlab simulink, build a simulink that models the harmonic oscillator equation

1) consider f(t) = 30 sin 5t (forced case)

make a plot for the solution (forced case) for first 30 s for b=0, m= 8kg, spring constant = 30 N/m, initial displacement is 1 m.

Make a plot also for the solution (unforced case) b= 6 N-s/m, m= 8kg, spring constant = 30 N/m, initial displacement is 1 m.

2) resonance frequency is compute the frequency and force the b = 6 N-s/m at . Plot this case

dx dx maf2+ ba+k = f(t) dx dx maf2+ ba+k = f(t)
