Static friction is the friction between two objects in contact with each other but it does not result in motion. Suppose you push a block placed on a rough surface. It does not move. The force provided by you is exactly equal to the frictional force provided by the rough surface. If you push a little more harder the opposing frictional force increases accordingly to balance the applied force. This happens until the frictional force value reaches its maximum. Since the two objects are balanced, it is called self adjusted force.
