Decide the mass of the valve stem

Reference no: EM13681388

A cyclist turns her bicycle upside down to repair it. She then notices that the front wheel is executing slow, small amplitude, back-and-forth rotational motion with period 12s. Treating the wheel as a thin ring of radius 30 cm and mass 600 g, whose only irregularity is the tire valve stem, decide the mass of the valve stem.
