A homogeneous pendulum rod of mass is install in the elevator car shown in the figure 2, the gravity g=10m/s, and the acceleration is a. Try: (1) to establish the differential equation of motion with the swing angle 0; (2) if the swing of the pendulum is very small, namely sin0~0, simplify the differential equation of motion and calculate its natural frequency @n. (Note: if to calculate @n, values of m, k, a,b, l equal to 2). a b www. k Fig.2 m A homogeneous pendulum rod of mass is install in the elevator car shown in the figure 2, the gravity g=10m/s, and the acceleration is a.
