third class! :)
The answer is that it is NOT. It is a first class lever. "Class 1: the fulcrum is located between the applied force and the load. Example: the crowbar" - Wikipedia In regular use, the fulcrum of the oar is attached to the top side or edge of the water craft, which is between the force being applied by the rower and the "load", being the resistance of the water itself. This makes the oar a classic example of a first class lever.

The answer is that it is NOT. It is a first class lever. "Class 1: the fulcrum is located between the applied force and the load. Example: the crowbar" - Wikipedia In regular use, the fulcrum of the oar is attached to the top side or edge of the water craft, which is between the force being applied by the rower and the "load", being the resistance of the water itself.
