The Physical Pendulum. A pendulum is formed by hanging a 60cm long stick of mass m from a pivot, as shown at left. Find the angular acceleration of the pendulum when the pendulum is displaced by a small angle θ, and show that the motion is simple harmonic motion in the limit of small oscillations. Find the period of the pendulum in this limit.

icen Consider the wing vibration model of Figure 4.20. Using the vertical motion of the point of attachment of the springs, x(t), and the rotation of this point, ?(t), determine the equa- tions of motion using Lagrange's method. Use the small-angle approximation (recall the pendulum of Example 14.6) and write the equations in matrix form. Note that G denotes the center of mass and e denotes the distance between the point of rotation and the cen??????????????????? ter of mass. Ignore...
