TECHNICAL DRAWING (SS 3)  MIDTERM HOME PRACTICE/EXERCISE (Freehand drawing/Sketching) As all senior secondary school three  Technical drawing students   in secondary and High schools  in West Africa and other parts of the world prepare for their final examinations, to graduate from their respective schools into Tertiary institutions, there is need to practice more of mechanical tools freehand drawing/sketching. Please find below some mechanical hand tools and sketch them in your sketch pad as further practice in Preparation for the final examinations.

 TECHNICAL DRAWING (SS 1)  MIDTERM ASSIGNMENT (On an A3 size drawing sheet answer the following questions) 1.  Construct an inclined line of any convenient angle of length 125mm and divide into 10 equal parts. 2. Construct a line AB of length 85mm and bisect at point C. 3. Construct parallel lines of 50mm length with equal distance of 30mm. 4. Construct a triangle XYZ of length XY=YZ=XZ = 60mm. Use XY as the base. What is the name of the triangle you have constructed. 5. Construct a triangle ABC of  lengths AB as the base =75mm, BC= 65mm and AC=65mm.      Measure angles ABC and CAB. What type of  triangle is ABC.

 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

 BUILDING HAND TOOLS In the Paper 3 of W.A.S.S.C.E, building hand tools are required to be drawn freehand especially in Section A questions 2 and 3. Therefore, it is very important that you are able to draw a resemblance of the required tool.  Knowing how to draw and what to draw requires information on what to draw. This information is best viewed in pictures so that you, as a student, carry the image of the building hand tool in your mind. It is very important that you acquaint yourself with the tools so as not to be caught napping in the examination hall. Most of these building hand tools are not what you see physically everyday because of not being in the building construction field or industry. This is efforts was made for you to see pictures of some of these building hand tool on this blog. The names, pictures and uses or brief explanation of the building hand tools are given so that you will not only see it but be able to describe what they are used for. 1.  Bolster Bolster is l
