3-2 If the system of Prob. 3-1 is excited by a harmonic force of frequency 4 cps, what will be the percentage increase in the amplitude of forced vibration
when the dashpot is removed?
(3-1 A machine part weighing 4.3 Ib vibrates in a viscous medium. Determinethe damping coefficient when a harmonic exciting force of 5.5 Ib results ina resonant amplitude of 0.50 in. with a period of 0.20 sec.)
