👉 The lowest form of engineering, often referred to as "basic" or "primitive" engineering, involves using simple tools and techniques to create functional objects or solve basic problems without advanced technology or complex machinery. This level of engineering relies heavily on manual labor, basic materials like wood, stone, or clay, and fundamental principles of physics and mechanics. Examples include crafting simple tools, building shelters, or creating rudimentary machines like levers or pulleys. The focus is on practicality and survival, rather than precision or innovation.
