Pendulum attached to rotating disc. A. Oct 3, 2017 · There's a pendulum with mass m and longitude L strapped to a disk with radius R that rotates with an angular velocity ω. And, the frequency of small oscillations equals to f = ω 2π . Thus, we can borrow the result from the pendulum problem to solve this one.  The usual gravity g is present. First, the equilibrium point apparently equals to θeq = 0. The point O is fixed in an inertial reference frame, the unit vectors e; and ez are fixed to the Problem 1. As such, it is just an additional mass ("point like object") attached to the rod. I agree with you. It clarifies that the disc does not contribute to the moment of inertia when it is free to spin because it does not rotate about the pendulum's hinge axis during oscillation. fz8i kkgqb aesi riuk 51j dppx0cw ixz 85e n8g tpxn
