What is Engineering?

4. Introduction
Engineering is:
“ The profession in which a knowledge of the mathematical and natural sciences gained by study, experience, and practice is applied with judgment to develop ways to use economically the materials and forces of nature for the benefit of mankind “
“ The application of science to the needs of humanity”
“The creative application of scientific principles to design or develop structures, machines, apparatus, or manufacturing processes, or works utilizing them singly or in combination; or to construct or operate the same with full cognizance of their design; or to forecast their behavior under specific operating conditions; all as respects an intended function, economics of operation and safety to life and property”
“Engineering is the discipline and profession of applying scientific knowledge and utilizing natural laws and physical resources in order to design and implement materials , structures, machines, devices, systems, and processes that realize a desired objective and meet specified criteria”

25. The drive from Oakland to Pinewood:
Brain teaser
The drive from Oakland to Pinewood:
I covered the uphill distance of 70 Km at 42 km per hour. The return journey from Pinewood to Oakland was downhill, and I managed to drive at 56 km per hour. What was my average speed for the entire journey?

26. Brain teaser
Average speed = Total distance / Total time Total distance = 2 × 70km. Time for uphill journey (from Oakland to Pinewood) = 70 / 42 hours. Time for downhill journey (from Pinewood to Oakland) = 70 / 56 hours. Total time = (70 / 42) + (70 / 56) Average speed = Total distance / Total time = 48km per hour. The common mistake made in solving this problem is to assume the average speed to be the arithmetic mean, i.e., ( )/ 2 = 49 km per hour.
