MECHANICAL ENGINEERING

OVERVIEW

Engineering drawing and engineering drafting are broad terms widely used to denote the graphic language. Technical Drawing is a broad term that adequately suggests the scope of the graphic language. It is rightly applied to any drawing used to express technical ideas.^[1] The ^[2]

“ The radiation of the sun in which the planet is incessantly plunged, pentrates the air, the earth, and the waters; its elements are divided, change direction in every way, andd, penetrating the mass of the globe, would raise its temperature more and more, if the heat acquired were not exactly balanced by that which escapes in rays from all points of the surface and expands through the sky.The Analytical Theory of Heat, J.

DESCRIPTIVE GEOMETRY

DESCRIPTIVE GEOMETRY.... portion of the Internet is still developing sites with a fixed and/or static approach to presentation. With the success of several social networking sites, performance and design scalability are no longer resigned to enterprise level class applications. Social networks and blogs demand a dynamic publishing solution for interactive content. Web development now requires sites to address publicly approved, fixed content and a need for interactive content creation. Whether one decides to purchase a complete packaged solution or have one designed around their needs and scale to meet future needs depends on the client.

APPLICATIONS OF DESCRIPTIVE GEOMETRY

MECHANICS · BASIC CONCEPTS · SCALARS & VECTORS · NEWTON'S LAWS · UNITS · LAW OF GRAVITATION · ACCURACY, LIMITS AND APPROXIMATIONS · FREE-BODY DIAGRAMS · REVIEW

``Although other scientists would deny that they should deal only with ideas that are strictly measurable, none would deny the great importance of exact measurement to science. There have been many instances in the history of science in which small but significant discrepancies between theory and accurate measurements have led to the development of new and more general theories. Such slight discrepancies could not have been detected if scientists had been satisfied with only a qualitative explanation of the phenomena.''^[1]
