Question

#2 Torsion clock Design a torsion clock made of steel (shear modulus 79.3 GPa, density 7.9 g/cm3) based on a torsion wire (length 0.2 m, diameter 0.3 mm), a rod (diameter 3 mm, length 20 cm) and two small masses (20 g each) attached to the rod. Position the masses on the rod such that the resulting oscillation time is 1 s! What is the track velocity of the masses at the zero transition. if the starting amplitude is 45°, what is the centrifugal force? sketch of the setup (see above) (torsion) spring constant of the wire i nertia of the rod position of the masses track velocity centrifugal points force 14 /30
