DRAWING AND SHOP-WORK.
Drawing: Mechanical and Projection Drawing.—Projections of cubes,
prisms and pyramids in simple positions; methods of revolving the solid into
new positions; method of changing the planes of projection; projections of
the three round bodies in simple positions and in revolved positions; sections
by planes parallel to the planes of projections; sections by inclined planes;
developments of prisms, pyramids, cylinders and cones; intersections of polyhedra
and curved surfaces; distances from a point to a point or a plane or a
line; angles between planes and lines. (One unit.)
Shop-work: Wood-work, Forging, and Machine-work.—The candidate
must present valid certificates covering at least 240 hours of competent
instruction with adequate appliances in these topics. About 80 hours should
be devoted to wood-work, 40 to forging, and 120 to machine-work. He should
be familiar with the usual shop processes, the standard methods of work, and
the properties of the ordinary constructive materials. (One unit.)
In these units a practical examination in drawing and in shop-work is
given to validate the certificate of training.
