F₁
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 = 2 kg
m2 = 2 kg
k1 = 133 N/m
k2= 155 N/m
k3=140 N/m
F1 = 269 cos(2.8t) N
F2 = 0.
