I am finding it very difficult to find frictional force & tension in this problem, since the system remains at rest. It requires something more than FBD & force eqations.
Q. Two blocks 10 kg(u=o.f) & 6kg(u=0.2) ( u:co-ef of friction) lie on a horizontal table, connected by string. (inextensible.) The 10 kg block is connected by a string passing over a pully to a 2kg block which hangs freely.
similarly, the 6kg block is connected to a 4kg block by string pully, which hangs freely. find the force of friction on the 2 blocks & tension in the string joining them.
U get 2 eqations
T+ F(on 6)= 4g
T=F(on 10) + 2g
2 eq. & 3 unknowns. How to solve?
