Who invented the crowbar?

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.

What is the fulcrum on a crow bar when you are prying up a nail?

The fulcrum is the point of support on the crowbar where it pivots as you apply force to lift the nail. It acts as the lever point to help you pry up the nail using less force.


How crow does not get electrocuted when it sit on the electric power lines?
