Mathematics, the science of structure, order, and relation that has evolved from elemental practices of counting, measuring, and describing the shapes of objects. It deals with logical reasoning and quantitative calculation, and its development has involved an increasing degree of idealization and abstraction of its subject matter. Since the 17th century, mathematics has been an indispensable adjunct to the physical sciences and technology, and in more recent times it has assumed a similar role in the quantitative aspects of the life sciences.

Welcome to the Practical platform of Electrical General Level 3. Please note all notes pertaining to practical items will be uploaded on this platform. 

Engineering drawing is an effective means of communicating technical ideas and problem solutions. Sketches are made to record ideas. Geometrical models are created from those sketches and are used for analysis. Finally, detail drawings or three-dimensional models are made to record the precise data needed for the production process. Visualizing, sketching, modelling, and detailing are how engineers and technologists communicate as they design new products and structures for our technological world. Actually, communication using engineering drawings and models is a language, a clear, precise language with definite rules that must be mastered if you are to be successful in engineering design. Components (machine parts) shown in a drawing can therefore be made by suitably skilled craftsmen of any nationality, provided they can ‘read’ an engineering drawing. If the drawings are correctly drawn and annotated (described) by means of notes and dimensions, the finished product will be exactly as visualized by the designer. Any misunderstandings when describing shapes and size by using only words and no drawings are thus avoided. In short, engineering drawing is a global way of communication in technical field.

This course is aimed to be a Demo for E-learning committee workshop 29-30 November 2021.
