QUESTION 15 What is the deformation response factor for a damped system with stiffness of 800N/m, and a mass of 18kg? The system is being forced by an oscillating load of 6sin(2t) kN and has a damping ratio of 0.33. Give the solution to 3dn. 1 poin QUESTION 16 1 poi The response of an undamped system to harmonic vibrations is highly dependent on the damping ratio of the system, when close to resonance. True False QUESTION 17 1 po The maximum response of a viscously damped system, subjected to a harmonic force, occurs when: The natural frequency of the system is slightly a. smaller than the frequency of the harmonic force b. The natural frequency of the system is slightly larger than the frequency of the harmonic force C. The natural frequency of the system is significantly smaller than the frequency of the harmonic force d. The natural frequency of the system equals the frequency of the harmonic force
