One reason part replacement and mass production became so commonplace was the introduction of _________ parts.
Interchangeable
Raw metal before it is processed
Ore
Casting
liquid poured into mold (hollow cavity for a desired shape)
Riveting

- also involved in developing rocket engines, artificial satellites, and spaceships
Automotive
- design, develop, test, and build vehicles of all kinds
- work may include engine design, fuel efficiency, lubricants, electrical systems, electronics, structures, hydraulics, materials, and safety systems
Biomedical
- design and build medical diagnostic and treatment instruments, prostheses, artificial organs, and pacemakers
- adapt computers to the needs of medical data processing and to modernize laboratory, hospital, and clinic structures and procedures
Ceramic
- specialize in heat-resistant materials, pottery, fiber optics, insulators, brick and tile, electronic materials, metal coatings, glass, abrasives, and cement
Chemical
- research and develop ways to use chemistry to increase economical and efficient production processes.
- design, construct, and operate equipment and factories that use those developed processes
Civil
- create, improve, and provide protection to the community environment, b y providing facilities for living, industry, transportation, and other constructions
Mechanical
