1. Construct a parabola when the distance ranging from focus and the directrix is 40mm.
Draw tangent and normal at any point P on the curve. [16]
2. A circle of 50mm diameter rolls along a straight line without slipping. Draw the
curve traced out by a point P on the circumference, for 1 complete revolution of
the circle. Name the curve. Draw a tangent to the curve at a point on it 40mm
from the line. [16]
3. Draw the projections of the subsequent points on the identical ground line, keeping the
Projectors 20mm apart.
(a) Point C, in the V.P. and 40mm above the H.P.
(b) Point D, 25mm beneath the H.P. and 25mm behind the V.P.
(c) Point E,15mm above the H.P. and 50mm behind the V.P.
(d) Point F, 40mm beneath the H.P. and 25mm infront of the V.P. [4×4]
4. (a) A line EF 40mm long is in the V.P. and inclined to H.P. The top view measures
30mm. The end E is 10mm above H.P. Draw the projections of the line.
Determine its inclination with H.P.
(b) A line measuring 80mm long has 1 of its ends 60mm above H.P. and 20mm
in front of V.P. The other end is 15mm above H.P. and in front of V.P. The
front view of the line is 60mm long. Draw the top view. [8+8]
5. A regular pentagon of length of 30mm side, has 1 of its corners on V.P. and its
surface is inclined at 600 to V.P. The edge, opposite to the corner on V.P, makes
an angle of 450 with H.P. Draw the projection of the plane. [16]
6. (a) Draw the projections of a pentagonal pyramid, base 30 mm edge and axis
50mm long, having its base on the H.P. and an edge of the base parallel to
the V.P. Also draw its side view.
(b) Draw the projections of a hexagonal pyramid, base 30 mm side and axis 60
mm long, having its base on the H.P. and 1 of the edges of the base inclined
at 450 to the V.P.
(c) A square pyramid, base 40mm side and axis 65mm, long has its base in the
V.P. 1 edge of the base is inclined at 300 to the H.P. and a corner contained
by that edge is on the H.P. Draw its Projections. [4+8+4]
