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.

Is a wheelbarrow first class lever second class lever third class lever or fourth class lever?

A wheelbarrow is a second-class lever. In a second-class lever, the load is between the effort (force) and the fulcrum, which allows for a mechanical advantage in lifting and moving heavy loads with less effort.


First Second and Third class levers are determined by the location of what?

The location of the effort, load, and fulcrum determine if a lever is a first, second, or third-class lever. In a first-class lever, the fulcrum is between the effort and the load. In a second-class lever, the load is between the fulcrum and the effort. In a third-class lever, the effort is between the fulcrum and the load.


What is the difference between a first class and a second class lever?

The main difference between a first class and a second class lever is the relative placement of the effort, load, and fulcrum. In a first class lever, the fulcrum is positioned between the effort and the load. In a second class lever, the load is between the fulcrum and the effort. Examples of first class levers include a seesaw, while examples of second class levers include a wheelbarrow.


Is a bolt a second class lever?

I do not believe a Bolt is classified as a lever as it does not have a fulcrum point. If it is, it would depend on what the bolt was being used for. If I had to guess, i would say class three


What are the disadvantages of a SECOND class lever?

The main disadvantage of a second-class lever is that it requires a greater force input compared to a first-class lever to move the load. Additionally, the load is located closer to the fulcrum, which can limit the range of motion of the lever.
