A flat uniform circular disk has a massof 2.30 kg and a radius of58.0 cm. It is suspended in ahorizontal plane by a vertical wire attached to its center. If thedisk is rotated 2.50 rad about thewire, a torque of 0.0800 N·m isrequired to maintain that orientation.

(a) Calculate the rotational inertia of the disk about the wire.

kg·m2

(b) Calculate the torsion constant.

N·m
