1 This book organized as two parts: Fundamentals and Applications. In the Part 1 Fundamentals, some key contents and review some of mechanics and materials aspects will be briefly introduced. In the Part 2 Applications, various machine components such as fasteners, springs, bearings, gears and shafts will be introduced. Chapter One 1. Introduction Machine design is a very broad decipline and covers mechanics, materials, thermal fluids, economics, ecology, arts, etc. How to study this course? To most of you this is your first professional engineering course which distinguishes from background science and mathematics courses. ( For example, solve x – 3x + 2 = 0, x = 1, 2; a man pushes a 10 kg mass object sliding on the floor using 10 N force what is acceleration? ) You cannot simply use equations and calculation to get a ‘correct or unique’ solution. You need to use engineering judgment and empirical knowledge to find your solution. Use cell phone as example. For example there are numerous workable designs of cars, you cannot say which car design is incorrect, but you can say some of them are better than others. 2.
