There is a cyllinder with radius 0.5 m fixed on the wall. We put a 6 metres long thin rod with mass 0.3 kg on it, which does not slip. I would like to calculate the oscillating time. It is a part of a clock, so the oscillating time is probably 1 or 2 seconds, but I got around 5 seconds. Please help me find a mistake.
The Attempt at a Solution
I got a wrong result
I am used to write M (torque) and J (moment of inertia)
