Apendulum is rigidly fixed to an axle held by two supports so that it can swing only in a plane perpendicular to the axle. the pendulum consists of a mass m attached to a massless rod of length (. the supports are mounted on a platform which rotates with angular velocity ω. find the pendulums stable equilibrium position and frequency for small amplitude oscillations, when ω is constant.

Two lightweight rods 24 cm in length are mounted perpendicular to an axle and at 180 ∘ to each other. at the end of each rod is a 480-g mass. the rods are spaced 42 cm apart along the axle. the axle rotates at 5.0 rad/s. (a) what is the component of the total angular momentum along the axle? (b) what angle does the vector angular momentum make with the axle? [hint: remember that the vector angular momentum must be calculated about the same point for both masses, which could be the cm.]
