Question Finding frequency of a specific mechanical oscillator -- horizontal rod on pivot


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.


relevant equation:


I am used to write M (torque) and J (moment of inertia)

Math Focus: Yet to find out.
By oscillating time do you mean settling time?

Also your images seem to not have uploaded properly.

duplicate post ...

oscillating of a rod put on a cylinder

... seems that posters on physics forums agreed with your solution. Why the additional post here?
