Principles for the final exam Examine your mastery of the concept/principle NOT those memory-based knowledge Coverage: modules 1-10 Format of questions: quiz, assignment

Principles for the final exam Operating or working rinciple of a process: The knowledge that governs a phenomenon or process or procedure Physics Solid cuts solid, creating shear stress in one solid. Why a material is cut off or broken? How a water-jet cutter works to break or remove materials? Water-jet cuts solid, creating shear stress in solid material.
