Which of the fundamental forces is the strongest force?

"There are four fundamental interactions that we know of. These four interactions account for all observed forces. These interactions are: Strong Nuclear, Electromagnetic, Weak Nuclear and Gravitational.

The strongest of these four is the Strong Nuclear. However, since this interaction operates at a very short range inside the nucleus (as little as 1 FM - which is a femto-meter or 10-15 meters) it is not the sort of force that we experience in everyday lives."
