A shovel performs several different functions. One of these is that it gives mechanical advantage as a lever. When does it act like a lever?

Answer 1

A shovel acts like a lever when it is used to lift or move heavy objects. The handle of the shovel acts as a lever arm, and the blade of the shovel acts as the fulcrum. The user applies force to the handle, which is then multiplied by the mechanical advantage of the lever, allowing the user to lift or move the object with less effort.
