A slender bar of mass m is pivoted at point O and supported at the ends by two springs as shown in Figure. A  

A slender bar of mass m is pivoted at point O and supported at the ends by two springs as shown in Figure. A 2 kg fan with rotating force F(t) = 200 sin 10 t, is mounted on point R. Given m = 12 kg, k 1500 N/m, c = 3000 Ns/m, 1 = 1 m. Determine the response of the system with initial disturbance 0 (0) 1 rad and (0) = 2 rad/s. 444 k 00000 0 1 Figure 14 Re P Q
