What is Technical Drawing? What is the necessity of Technical Drawing? Technical drawing or drafting, is the demonstration and discipline of composing drawings that visually communicate how something capacities or is developed. Technical drawing is basic for imparting thoughts in industry and engineering. To make the drawings more clear, individuals use familiar symbols, perspectives, units of measurement, notation systems, visual styles, and page design. Together, such conventions constitute a visual language and help to guarantee that the attraction is unambiguous and moderately straightforward. A large number of the images and standards of Technical drawing are systematized in an international standard called ISO 128. The requirement for exact correspondence in the arrangement of a practical record recognizes specialized drawing from the expressive drawing of the visual expressions. Creative drawings are emotionally deciphered; their implications are duplicated and decide...
Post Summarisation: 1. Spiral 2. Archimedean Spiral 3. Logarithmic Spiral Spiral: When a line rotates on a plane about one of its end, on such a way that a point moves along the line continuously in one direction (inward or outward), the curve traced out by the moving point is called a S piral . The point about which the curve line rotates is called a P ole . The line joining any point on the curve with the pole is called the Radius Vector and the angle between this line and the line in its initial position (or, Horizontal axis line) is called the Vector angle or Vectorial angle . Each complete revolution of the curve is termed the C onvolution . A spiral may make any number of convolutions before reaching the pole. Archimedean Spiral: When a curve is traced out by a moving point in such a way that its movement inwards or outward from the pole is uniform with the decrease or increase of Vectorial...
