Which example represents a class two lever
A wheelbarrow is an example of a class two lever. In a class two lever, the load is located between the fulcrum and the effort. In a wheelbarrow, the wheel acts as the fulcrum, the load (the weight being carried) is located between the wheel and the handles, and the effort is applied by the person pushing the handles.
A class two lever is a type of lever where the load is located between the fulcrum and the effort. In other words, when the effort is applied to one end of the lever, it creates a greater force on the load located at the other end.
A typical example of a class two lever is a wheelbarrow. In a wheelbarrow, the load (such as a pile of dirt or rocks) is placed on the wheelbarrow itself, acting as the fulcrum. The handles of the wheelbarrow serve as the effort, where a person applies force to lift and move the load. The load is situated between the fulcrum (wheelbarrow) and the effort (handles), making it a class two lever.
Another common example of a class two lever is a nutcracker. The hinge of the nutcracker acts as the fulcrum, the nut being cracked is the load, and the force applied on the other end of the nutcracker is the effort. The load (nut) is placed between the fulcrum (hinge) and the effort (force applied), which is characteristic of a class two lever.
In summary, a class two lever is one where the load is located between the fulcrum and the effort, and examples such as a wheelbarrow and a nutcracker illustrate this type of lever.
A class two lever is a simple machine that consists of a rigid beam or lever pivoting on a fulcrum, with the load positioned between the fulcrum and the effort applied to move the load. In this type of lever, the effort arm is longer than the load arm.
An example of a class two lever is a wheelbarrow. In a wheelbarrow, the wheel acts as the fulcrum, the load (such as a pile of dirt) is placed in the bucket, and the effort is applied by lifting the handles. The handles are located farther from the wheel (fulcrum) than the bucket (load), making it a class two lever.
