Teach Engineering Graphics to First Semester Students of Engineering
It is best to start this teaching process with exposing students to good quality technical drawings of simple objects like nuts and bolts, shafts, plates with holes drilled in them, simple cast objects, tools, etc. These objects could be picked up from a hardware store. The drawings should be detailed with all the elements expected of a good shop drawing. Each student should be given an object and its technical drawing and asked to spend time studying it. In a class of 40 there could be say10 different objects with 4 of each (more variety the better). Every student should also have with him a Vernier Caliper, Micrometer, Steel Scale and Measuring Tape. Start with explaining how to use the vernier caliper and micrometer and guide the students to discover how completely and accurately the drawing represents the object. Concepts like plan, elevation, side views, sections as well as nuances of dimensioning, tolerances and finishes should emerge out of discussions in the classroom....
