Mechanical systems drawing is a type of technical drawing that shows information about heating, ventilating, air conditioning and transportation (elevators and escalators) around a building. [1] It is a tool that helps analyze complex systems.
A pattern book, or architectural pattern book, is a book of architectural designs, usually providing enough for non-architects to build structures that are copies or significant derivatives of major architect-designed works. A number of pattern books have been very influential in spreading architectural styles.
An engineering drawing is a type of technical drawing that is used to convey information about an object. A common use is to specify the geometry necessary for the construction of a component and is called a detail drawing.
Discarding the time-worn name "Mechanical Drawing" he coined a new title and wrote a text, "A Manual of Engineering Drawing for Students and Draftsmen", which was published in 1911. He was ably assisted by Assistant Professor Robert Meiklejohn, Instructors Owen E. Williams, Arthur C. Harper, Cree Sheets, Frederick W. Ives, William D. Turnbull ...
Marble is a rock resulting from metamorphism of sedimentary carbonate rocks, most commonly limestone or dolomite. Metamorphism causes variable re-crystallization of the original carbonate mineral grains. The resulting marble rock is typically composed of an interlocking mosaic of carbonate crystals.
Marks' Standard Handbook for Mechanical Engineers is a comprehensive handbook for the field of mechanical engineering. Originally based on the even older German Hütte, it was first published in 1916 by Lionel Simeon Marks. In 2017, its 12th edition, published by McGraw-Hill, marked the 100th anniversary of the work. The handbook was translated ...
Example of true position geometric control defined by basic dimensions and datum features. Geometric dimensioning and tolerancing (GD&T) is a system for defining and communicating engineering tolerances via a symbolic language on engineering drawings and computer-generated 3D models that describes a physical object's nominal geometry and the permissible variation thereof.
A rail repair dutchman is typically a 4–6-inch (100–150 mm) long piece of rail that is cut in advance for the purpose and carried by a section crew. If the gang finds a rail with a chipped or broken end, they remove the connector plates ( fishplates ), cut out the damaged section, replace it with the dutchman, and bolt the connectors back ...
