TECHNICAL DRAWING [65 Marks]

Answer all the questions

Strictly geometrical methods are to be used. Lines that are parallel, perpendicular or inclined at angles of 300, 450 or 600 to other lines may be drawn without construction lines being shown. All other construction lines must be shown clearly. Accuracy and good draughtsmanship are essential. A3 sheets of drawing papers should be used. Both sides may be used.All dimensions on the diagrams are in millimetres.1.
