Question
Three masses, m, =3 kg, m2 = 5.5 kg, and m3 = 2 kg, are attached to springs, k1 = 50 N/m, k2 = 35 N/m, k3 = 25 N/m, and k4 = 20 N/m, as shown below. Initially the masses are positioned such that the springs are in their natural length (not stretched or compressed); then the masses are slowly released and move downward to an equilibrium position as shown. The equilibrium equations of the three masses are:
