Q-1) Obtain the response of a system with an undamped f

Q-1) Obtain the response of a system with an undamped frequency ? to the periodic load shown in below Figure. The stiffness of the system is k and damping is 10% of critical. The exciting frequency O = 1.5?). Answer Q-2) Obtain the discrete Fourier transform of the function shown in below Figure. Use a sampling interval of 0.1 s and a period of 1 s. Now obtain the inverse Fourier transform of the frequency function obtained by you. Compare this inverse transform with the original time function and explain the differences if any between the two.
