Uniform bar OA rotates around endpoint O and position angle 0= 0 when the bar is horizontal and in static equilibrium. The mass of the bar is m = 20 kg, the length of the bar is L=1.2 m , k= 6000 N/m for the spring, and c= 320 N-s/m for the damper. The bar is initially at rest with 0 0 when force F(t) is applied to the end of the bar. Find the response 0(t) if force F(t)...
