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 0.55 cm, connected to the balance staff by thin spokes of negligible mass. The total mass of the balance wheel is 0.90 g.
(a) What is the moment of inertia of the balance wheel about its shaft?
(b) What is the torsion constant of the hairspring?
