Answer 1

Answer:

5.A uniform metal disc of diameter 0.1 m and mass 1.2 kg is fixed symmetrically to the lower end of a torsion wire of length 1m and diameter 1.44 ×10-3 m, the upper end is fixed. The time period of torsional oscillations is 1.98s. Calculate the rigidity modulus of the material of the wire.
