When does a rigid body said to be in equilibrium ? State the necessary condition for a body to be in equilibrium

Answer»

Solution :For translation equilibrium
`sum vecF_(ext)=0`
`ALPHA` in CYLINDER `alpha_(C) = TAU/(I)`
`alpha` in sphere `alpha_(S) = tau/I`
`alpha_(C)/alpha_(S) =I_(S)/I_(C) = (2/5 MR^(2))/(MR^(2)) -2/5`
