A pulley of mass M and radius R centered at O. If a rope is pulled at its both end by forces F1 and F2 from its both end then what will be the net torque on pulley ? and what will be the resultant force on center pin?considering no gravitational force is there. will the resultant force be F1+F2? if yes then if i take one of these force As 0 say F1=0 then net force at centere should be equal to F2. but practically it seems not to be true. it seems to be 0 . please explain what will be the net force in both the cases...
