(i) An SDOF system with a natural frequency of 2 Hz and a damping ratio of 20% un- dergoes resonance under the action of a harmonic load. What is the frequency of the applied harmonic load a. 0.50 Hz b. 1.92 Hz c. 2.00 Hz d. 12.6 Hz e. None of the above f. The provided information is insufficient to determine the frequency of harmonic load that will induce resonance (ii) An SDOF system with a natural period of 4 s is subjected to a harmonic load of frem quency 2 Hz. How many cycles of steady-state displacement response will the struc- ture complete in 1 s? a. 0.5 cycles b. 1 cycle c. 2 cycles d. 4 cycles e. None of the above f. The provided information is insufficient to compute the number of cycles com- pleted in 1s
