The second phase (1890-1930), dominated by electrical devices (plate 10A & 10B) and chemicals. The revolution introducedtelephones, electrical devices (plate 10C), the internal combustion engine, surface transport system (automobiles), sea (ocean-liners), and air (aircraft). The essential character of the second phase revolution is mass production of consumer goods and the mechanization of manufacturingto serve the increasing population around the globe.
The process of interchangeable parts of mass products drastically reduced the cost of the products in term of manufacturing process, assembling and maintenance. The high quality steel products gave increased low cost high performance quality products to the mass. The Second Phase of Revolution witnessed increased quality steel, chemicals, and electrical energy and petroleum productions.
