What type of lever is represented by a wheelbarrow?

A wheelbarrow functions as a Class 2 lever, which is characterized by the load being positioned between the effort applied and the fulcrum. In a wheelbarrow, 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 load. This arrangement allows for the mechanical advantage of moving larger loads with less effort compared to lifting them directly.

Class 2 levers, like wheelbarrows, typically allow the user to exert a force that is less than the weight of the load being lifted, which is a key feature in their design and utility. This type of lever is efficient for tasks that require the lifting of items, especially when the load is heavy, which is common in gardening and construction projects where wheelbarrows are frequently used.
