Consider the pendulum mechanism of Figure P2.27 which is pivoted at point O. Calculate both the damped and undamped natural frequency of the system for small angles. Assume that the mass of the rod, spring, and damper are negligible. What driv- ing frequency will cause resonance? //// 1 = 0.10 m m 4₁= = 0.05 m 1₂ = 0.07 m C Figure P2.27 F(t) Consider the pendulum mechanism of Figure P2.27 which is pivoted at point O.
