Technology advances life

Oluwadimu O.M

 Technology advances life in every sphere.

It is not sufficient to dream big but take active steps at making your dream a reality.
This Blog shall be used extensively for learning activities in Technical drawing. It shall contain reviews of work done in class, assignments and videos to show how images and Geometrical constructions are done.
It shall contain e-books from which you can learn more beyond what was done in class.
Once again welcome on-board.


Technical Drawing is divided into the following areas

  1. Plane Geometry
  2. Solid Geometry
  3. Building drawing and
  4. Mechanical drawing.

TOPICS UNDER PLANE GEOMETRY
  • Introduction to Technical Drawing
  • Drawing instrument and materials
  • Drawing Board Practice
  • Safe working habits
  • Lines and line work
  • Angles
  • Triangles
  • Circles
  • Circles and Triangles - Inscribe, circumscribe and escribe circles
  • Quadrilaterals
  • Polygons
  • Hedrons - Icosahedron, Tetrahedron etc
TOPICS UNDER SOLID GEOMETRY INCLUDES
  • Development of Geometrical solids
  • True shape of sections of geometrical solids
  • Intersection of geometrical solids
  • Isometric Projection
  • Oblique Projection
  • Computer aided design
  • Point and Line in space
  • Planes in space- Triangular laminar
  • Orthographic Projection
TOPICS UNDER BUILDING DRAWING INCLUDES
  • Freehand drawing
  • Introduction to building drawing
  • How to draw building Plan, elevations and sections
  • How to Prepare building working drawing
  • Details of building components
TOPICS UNDER MECHANICAL DRAWING INCLUDES
  • Screw threads, fasteners and lock devices
  • Simple Machine working drawing.
  • Assembly drawing
  • Sections and sectional views
NOTE
Every drawing Practice in Technical drawing must be taken with all seriousness as the result will be tremendous when writing external examinations.

MECHANICAL DRAWING

 MECHANICAL DRAWING. In technical drawing, mechanical drawing is an optional question in WASSCE AND NECO SSCE.  Mechanical drawing has to do with proper understanding of orthographic Projection, isometric insight view of the object as presented in 2 Dimension, sectional views of objects in 2 dimensions, Screws, lock devices and fasteners and assembly of objects.  Most often WAEC will give a brief of how to assemble the given mechanical tool while NECO in most cases does not give a brief. Therefore, it is important that the student learn and practice more on mechanical drawing before attempting it. In my own view, mechanical drawing is simpler compared to building drawing at the school certificate level. Find below some examples of how Mechanical drawing questions are set in WASSCE. 1. The figure below shows a bevel pulley mounting bracket, with the parts assembled, draw full scale the following views i. Sectional front elevation on cutting Plane T-T ii. Sectional end elevation on cutti
