It is assumed that the student has already learnt to draw to scale, and
that he can draw two or more views of the same object in simple or
orthographic projection. To pass in machine construction and drawing, he
must be able to apply this knowledge to the representation of machinery.
He must be acquainted with the form and purpose of the simpler parts of
which machines are built up and must have had some practice in drawing
them. To test his knowledge, rough dimensioned sketches, more or less
incomplete, of simple machine details will be given him, and he will be
required to produce a complete drawing in pencil to a given scale. Two
or more views of at least one subject will be required, and these must
be so drawn as to be properly projected one from the other, _in order to
show that the student appreciates that he is producing a representation
of a solid piece of machinery, and not merely copying a sketch. No
credit will be given unless some knowledge of projection is shown._ The
centre lines of the drawings should be shown, and parts cut by planes of
section should be indicated by diagonal shading. Bolts and other
fastenings should be carefully shown where required. Any indication that
a candidate has merely copied the sketches given, without understanding
the part represented, will invalidate his examination.
