LLC k L3 L2 Li Consider a rectangular parallelepiped of mass m = 3.203 kilogram and dimension b = 0.577 meter and l = 0.429 meter in an xy-plane that is connected by a linkage of length L3 = 0.52 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 = 0.544 meter and a linkage L2 = 0.357 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 = 1027.166 newtons/meter and a damper c = 607.811 newton-meter/second. It is known that the equation of motion + cei + ke0 = 0 for the rotation of linkage L3 takes the form @= Aje - stv V52-1)wnt + Aze -1)wnt when the motion is over-damped. It is desired to determine numerical values of me, Ce, ke, wnic Find to 4 significant figures: ke
