(a) For a forced oscillation at resonance (&> = &>0),
Chapter 14, Problem 14.63(choose chapter or problem)
(a) For a forced oscillation at resonance (&> = &>0), whatis the value of the phase angle 0 in Eq. 14-22? (b) What,then, is the displacement at a time when the driving forceFext is a maximum, and at a time when Fext = 0? (c) What isthe phase difference (in degrees) between the driving forceand the displacement in this case?
