A uniform, solid metal disk of mass 6.50kg and diameter 24.0 cmhangs in a horizontal plane, supported at its center by a verticalmetal wire. You find that it requires a horizontal force of 4.23 Ntangent to the rim of the disk to turn it by 3.34 degrees thustwisting the wire. You remove this force and release the diskfrom rest. a) what is the torsion constant for the metal wire?
