Consider a rectangular parallelepiped of mass m = 9.7 kilogram and dimension b = 4.4 meter and l = 6.6 meter in an xy-plane that is connected by a linkage of length L3 = 5.7 meter from the top edge of the parallelepiped to a pivot at point O as shown in the diagram. Attached perpendicular to linkage L3 is another linkage composed of a linkage L1 = 5.9 meter and a linkage L2 = 1.1 meter, such that the linkage L3 is initially vertical and then rotates by a small angle 8. Connected to linkage Li is a spring k = 4.5 newtons/meter and a damper c = 4.8 newton-meter/second. It is known that the equation of motion meö + ceh + k 0 = 0 for the rotation of linkage L3 takes the form A = Ajel-s+12-1), when the motion is over-damped. It is desired to determine numerical values of me, Ce, ke, wn, Find to 4 significant figures: 5 + A2el-5-782-1)wnt
