how do you know when a system is in equilibrium?

when no external force is required for a system to work.. that means
the consumed energy = the energy emmited & the cycle is going on....
however due to various reason of nature like friction & waste... we cannot have such a system practically....

Equilibrium means balancing a system. In reality perfect equilibrium does not exist. It is imposible to put a weight on a balance scale and put a mass on the other side and say that the object balances exactly. This is what gave rise to Heinsenburg's indeterminancy principle.
So In our Universe equilibrium is not static .It is dynamic. that means it continually changes but only by small amounts, and if it reaches the perfect point of balance , its only momentary.This is not an easy question to answer and it requires a good imagination to understand it.

To be in equilibrium it has to be in a state of no change. It is either: a. not moving b. moving at a constant velocity c. the forces cancel eachother out. The net force is alwayz zero when it's in equilibrium

A system will be in equilibrium when:
(a) the resultant force acting upon it is zero, and
(b) the resultant torque acting upon it is zero.
