A Class 2 lever is characterized by the placement of the load between the effort (force applied) and the fulcrum (pivot point). In this type of lever, the effort arm is longer than the load arm, allowing for a mechanical advantage that makes it easier to lift the load.

A wheelbarrow is a prime example of a Class 2 lever. The wheel acts as the fulcrum, the load is placed in the bucket of the wheelbarrow, and the effort is applied at the handles to lift the front of the wheelbarrow. Since the wheel is positioned at one end and the load is in the middle, the design enables the user to lift heavy loads with less effort compared to directly lifting the load.

In contrast, a seesaw is typically a Class 1 lever with the fulcrum positioned in the center, allowing the two ends to act as effort and load. Scissors represent a Class 2 lever as well when considering how the blades work, but in the context of the question, the design of the wheelbarrow illustrates a clearer, more common example. A broom functions as a Class 3 lever where the fulcrum is at the base and the effort is applied closer to the br
