A mass m=15 Kg that moves over a smooth surface is attached to one end of a bar and to the vertical surface by a spring (constant k). The bar is 4 m long, with a=2 m, and a moment of Inertia of Jo=20 kg m2. The other end of the bar is attached to a spring (constant k) and a damper (constant c). If the bar vibrates with small rotational displacement and the response (in degrees) is shown in the graph. Determine the equation of motion of the system and the constant of the damper. k Ooooo 171 Bar (Jo, 2a) a k 0000 2 10.5.1.1 10.1. 0.250 0 0 1 02 03 05 07 14 16 2 2 O 146.7 Ns/m O 76.5 Ns/m O 60.9 N s/m 133.4 N s/m
