Lecture Engineering drawing and design - Lecture 13: Principles of mechanical design. The following will be discussed in this chapter: Preliminary design for mechanical systems, learn phases in mechanical design. | Design web Design web Objectives for today ME 1110 – Engineering Practice 1 Engineering Drawing and Design - Lecture 13 Preliminary design for mechanical systems Learn phases in mechanical design Principles of Mechanical Design Prof Ahmed Kovacevic School of Engineering and Mathematical Sciences Room CG25, Phone: 8780, E-Mail: 1 Ahmed Kovacevic, City University London 2 Ahmed Kovacevic, City University London Design web Design web Science - Engineering Mechanical Engineering Design Laws of nature Input System of components In 1911, a great mathematician named Theodore Von Karman wrote: “Scientists discover what is, engineers create what has never been.” Output ‘Name of the game’ Analysis To find Output Reverse analysis Science Engineering Input Laws System In 1989, Edward B. Fiske wrote: “The scientist seeks to understand the world and operates against an absolute standard. His findings either describe nature accurately or they do not. Skills Deduction Deduction Induction By contrast, the engineer is problem oriented. He seeks not to describe the world but to change it. Analysis & Synthesis Science explains what is - Engineering creates what never was Mathematics is neither science not engineering Physics and Chemistry are science but notAhmed Kovacevic, City University London engineering 3 The engineer lives in the world where science and values meet.” 4 Ahmed Kovacevic, City University London Design web Design web Mechanical Design Engineering -> Mechanical Design Process Engineering design process an iterative decision making activity, to produce plans by which resources are converted, preferably optimally with due consideration for environment into systems and devices to meet human needs. ( ) Mechanical design process is the use of scientific principles and technical information along with innovations, ingenuity or imagination in the definition of a .
