A certain alarm clock ticks four times each second, with each tick representing half a period. The balance wheel consists of a thin rim with radius 0.60 cm , connected to the balance staff by thin spokes of negligible mass. The total mass of the balance wheel is 0.85 g. Part A What is the moment of inertia of the balance wheel about its shaft? Express your answer with the appropriate units. HA I = Value Units Part B What is the torsion constant of the hairspring? Express your answer in N m/rad. ΑΣφ K = N. m/rad A certain alarm clock ticks four times each second, with each tick representing half a period.
