1. Enabled building of factory away from rivers powered machines = steam power (steam power enabled for factories to be established anywhere. It also provided substantial potential and could be utilized to power huge machines )
2. Developed system of interchangeable parts; increased production =Eli Whitney (at his arsenal Eli Whitney discovered the use of interchangeable elements and the milling device)
3. Made putting together of goods piece by piece; increased production greatly = assembly line (an assembly line is a construction process (oftentimes called a progressive machine) in which parts (interchangeable parts) are added as the semi-finished assembly passes from workstation to workstation where other parts are attached in series until the final assembly is designed. )
4.provided a tough, efficient building material for industrial purposes = steel (steel is an alloy of several metals but it consists of more iron than other minerals. Steel is solid and potent than iron)
