A bolt of mass 10 g is welded tangentially to the end of a torsion spring with a 2.6 cm radius. The spring is attached to the center of the board with the bolt resting horizontally at equilibrium directly above the center of the spring. (a) The board is rotated 83º, at which time the bolt points vertically. What is the stiffness of the torsion spring. 0.00174773 N*m/rad x 1 (b) If the board is rotated to 90°, then what is the angular extension of the spring in radians? [Assume the extension is smaller than 150.]
