Which one of the following statement is incorrect regarding to engineering?
ANS :NONE The discipline of engineering is extremely broad and encompasses a range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied science, technology and types of application. Engineers, regardless of their background, follow certain steps when designing the products and services we use in our everyday lives. Engineering has a direct and vital impact on the quality of life for all people.
define Engineering
ANS: ALL OF ABOVE A person specially trained to design and build machines, structures, and other things, including bridges, roads, vehicles, and buildings... Engineering is the application of mathematics, as well as scientific, economic, social, and practical knowledge to invent, innovate, design, build, maintain, research, and improve structures, machines, tools, systems, components, materials, processes, solutions, and organizations. Engineers has a good grasp of fundamental physical and chemical laws and mathematics and apply these laws and principles to design, develop, test, and supervise the manufacture of millions of products and services.
