Describe a class 2 lever and give one example of a class 2 lever..

Answer 1

A class 2 lever is a type of lever where the load is located between the effort and the fulcrum. In this type of lever, the effort is applied on one side of the fulcrum and the load is on the other side. The force applied is greater than the force generated by the load, making it easier to lift heavy objects with less effort.

One example of a class 2 lever is a wheelbarrow. In a wheelbarrow, the handle acts as the effort, the wheel acts as the fulcrum, and the load (such as dirt or rocks) is placed in the container. By pushing down on the handle, the load is lifted with less effort due to the mechanical advantage provided by the lever.
