What is the amplitude of vibration of mass 1 oscillating at the input frequency? (This is just another way of asking for the amplitude of the particular solution). The answer must
be positive. Use scientific notation with 3 significant figures. Omit units.
Use
m1 = 1 kg
m2 = 4 kg
k1 = 107 N/m
k2 = 135 N/m
k3 = 117 N/m
=
F1 376 cos(3.6t) N
F2 = 0.
