The free oscillations of a mechanical system are observed tohave a certain angular frequency ?1. The same system,when driven by a force F0cos?t, has a power resonancecurve whose angular frequency width, at half-maximum power, is?1/5.
(a) At what angular frequency does the maximum power inputoccur?
(b) What is the Q of the system?
(c) The system consists of a mass m on a spring of springconstant k. In terms of m and k, what is the value of the constantb in the resistive term -bv?
