I am going to hazard a guess that crowbars are so basic, so simple and useful in so many ways, that their use [levers] in one form or another goes back to the earliest periods of the human species. It would be very much the same for the wheel. Their first use is lost in the far distant ages past.
The origin of the word crowbar is suspected to be from the 1400's when it was called a crow bar. It is believed that the tool was called this because the bar looks like a crow's beak or crow's foot at one end and is used the same way a crow pries open a nut.

The mechanical advantage of the crowbar is 10. This is calculated by dividing the load force (400 N) by the effort force (40 N). In this case, the mechanical advantage shows that the crowbar amplifies your force by a factor of 10 to lift the rock.
