The figure below shows a dynamic system in a horizontal plane pivoted at point O. The system comprises a rigid bar with transverse springs attached at a distance a= 0.7 m from the pivot point. A mass M- 2kg is situated at the end of the bar, a further distance b 0.7 m from the spring attachment points. The bar has mass m 1 kg. The two. springs have stiffness K 4kN/m and K₂ 15kN/m respectively. The mass is connected to a damper with damping constant C10Ns/kg and forced by a dynamic loading F F, cos(ft) where the magnitude of the load is F50 N, the driving frequency is ft 43 rad/s, and time is t (s). Determine the amplitude of the total rotational m(a+b). Note Assume that clockwise response in degrees at t=0.1 s. given zero initial conditions. Note: the mass moment of inertia of rigid bar about pivot point is J is the positive direction. 2.14 degrees -0.73 degrees 0.33 degrees -0.41 degrees 0.85 degrees M F(t) Rigid bar I Activate Windows
