Question 2 A single degree of freedom, translational, mechanical system has an equivalent mass of 1 kg. The damping ratio and natural frequency, measured experimentally, are 1/72 and 2/2 rad.s", respectively. The system is subjected to a harmonic excitation force of Scos(31) N and the initial applied displacement and velocity of the system are zero. (a) Determine the equation of motion for the system. [2] (b) Using the transfer function approach, derive an expression of the displacement x in the system as a function of time t. [16] (c) Hence, calculate the displacement of the system at 15 s. [2]
