GEOMETRICAL AND MECHANICAL DRAWING (869)

This subject may not be taken with Geometrical and Building Drawing

Candidates will be required to reach a minimum standard in the subject as a whole. The use of drawing board,
tee-square and set-square will be required. (Candidates may, if they wish, use a drawing board fitted with a
parallel motion straight edge. The use of drafting machines will be permitted). A2 size paper will be used. The
recommendation of IS:696-1972 Indian Standard, Code of Practice for General Engineering Drawing should be
followed.

CLASS XI
There will be two papers in the subject:
Paper I - Theory: 3 hours…… 80 Marks
Paper II - Project Work ……. 20 Marks

PAPER I (THEORY) : 80 MARKS
SECTION A
Plane Geometry
Construction and use of scales including diagonal scales. Enlargement and reduction of irregular plane figures.
Construction of triangles, quadrilaterals and polygons. Similar plane figures. Problems on circles, tangents and
normals. Loci such as the paths of points in simple link mechanisms. Methods of construction of ellipse, including
its elementary properties, parabola and rectangular hyperbola; cycloidal and involute curves.

SECTION B
Solid Geometry
Orthographic projection. (Diagrams printed in the question papers may be in either First or Third Angle
projections; the projection used will be stated. Solutions in either First or Third Angle projections will be
accepted). Projection involving use of auxiliary planes; simple problems on auxiliary projection. Simple problems
on the intersection of prisms, pyramids, cylinders, right circular cones, and spheres. Determination of true length
of a line in space: sections and surface development of prisms, pyramids, cylinders and right circular cones. Helix
treated as a locus with applications on the projection of helices. Isometric and oblique projection without the use
of isometric scale.
