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.
