Pat used a lever, specifically a crowbar, to pry off the top of the wooden box, which is a type of simple machine that allows lifting heavier loads with less force.
The type of simple machine that Pat used to pry off the top of the wooden box is a lever. A crowbar acts as a lever, which is a rigid bar that pivots about a point, known as the fulcrum, to apply a force on an object at another point. When Pat applied a force to one end, the crowbar magnified that force at the other end to lift the lid of the box. This is because levers can give a mechanical advantage, allowing smaller forces to lift heavier loads.

Pat used a crowbar, which is a first-class lever, to pry off the top of the wooden box. This lever amplified his effort, making it easier to lift the lid. Levers like the crowbar are essential simple machines that help reduce the amount of force needed to perform tasks.
