Emergence definition

A lever is a mechanical device consisting of a rigid bar or beam pivoting around a fixed point, used to amplify or change the direction of applied force to lift or move objects, emerging from the combination of a tool, which requires system, force, and pattern, and a beam, a structural element within a building that occupies space and is governed by physical laws.
