  • Fluid Kinematics deals with the motion of fluids without necessarily considering the forces and moments which create the motion. Two ways to describe motion are Lagrangian and Eulerian description. Lagrangian description of fluid flow tracks the position and velocity of individual particles. (eg. Brilliard ball on a pooltable.)

  • where V is the volume worn away, W is the normal load, x is the sliding distance, H is the hardness of the surface being worn away, and k is a nondimensional wear coefficient dependent on the materials in contact and their exact degree of cleanliness. The term k is usually interpreted as the probability that a wear particle is formed at a given asperity encounter. Equation (21.5) suggests that the probability of a wear-particle formation increases with an increase in the real area of contact, Ar (Ar = W=H for plastic contacts), and the sliding distance. ...

  • Whenever I withdrew to the computer room, my wife would say that I was off to my “fun and games.” I would flatly deny this accusation, saying that it was serious work that I was involved in. But later, when I emerged with a twinkle in my eye and excitedly asked her to take a look at my latest rendering, I knew that she was right. Working with 3D graphics is pure “fun and games.” My goal in writing this book was to take all my fun years of playing in 3D and boil them down into something that’s worthwhile for you—the reader. This goal was compounded...
