Explanation:
The assertion that a lever is a simple machine is true. The reasoning behind it is accurate as well: a lever typically consists of a rigid bar (the beam) and a fulcrum (a fixed point around which the lever rotates). It functions by applying a force at one point to move an object at another point, allowing humans to lift or move heavy objects with less effort by leveraging the force applied. Levers are fundamental simple machines used in various tools and mechanisms, demonstrating the principle of mechanical advantage by making work easier through the multiplication of force.
