1. The problem statement, all variables and given/known data a thin wire of crosssection area 10^-2 m^2 is used to make a ring of radius 1/10 m. it is given ω=2 rad/s on a smooth table about its centre. find stress in ring?( mass/length of wire is 1 kg/m.) 2. Relevant equations s=f/a f=mv^2/r 3. The attempt at a solution my only difficulty is the area on which i should take the force to be acting.
