1. (a) Draw a hyperbola when the distance between its focus and directrix is 50 mm
and eccentricity is 3/2. Also draw the tangent and normal at a point 25 mm
from the directrix. (20)
OR

2. (a) A line PQ has its end P, 10 mm above the HP and 20 mm in front of the VP.
The end Q is 35 mm in front of the VP. The front view of the line measures 75
mm. The distance between the end projectors is 50 mm. Draw the projections
of the line and ¯nd its true length and its true inclinations with the VP and
HP. (20)
OR
2. (b) Draw the projections of a circle of 70 mm diameter resting on the H.P. on a
point A of the circumference. The plane is inclined to the H.P. such that the
top view of it i s an ellipse of minor axis 40 mm. The top view of the diameter,
through the point A is making an angle of 45± with the V.P. Determine the
inclination of the plane with the H.P. (20)
3. (a) An equilateral triangular prism 20 mm side of base and 50 mm long rests with
one of its shorter edges on HP such that the rectangular face containing the
edge on which the prism rests is inclined at 30± to H.P. The shorter edge resting
on HP is perpendicular to VP. (20)
OR
3. (b) A square pyramid of base 40 mm and axis 70 mm long has one of its triangular
faces on VP and the edge of base contained by that face perpendicular to HP.
Draw its projections. (20)
4. (a) A hexagonal prism of side of base 35 mm and axis length 55 mm rests with its
base on H.P such that two of the vertical surfaces are perpendicular to V.P. It
is cut by a plane inclined at 50± to H.P and perpendicular to V.P and passing
through a point on the axis at a distance 15 mm from the top. Draw its front
view, sectional top view and true shape of section. (20)
OR
4. (b) Draw the development of the lateral surface of the lower portion of a cylinder
of diameter 50 mm and axis 70 mm. The solid is cut by a section plane inclined
at 40± to HP and perpendicular to VP and passing through the midpoint of
the axis. (20)

5. (a) Draw the isometric projection of the object from the views shown in Figure
5(a). (20)
OR
5. (b) Draw the perspective projection of a cube of 25 mm edge, lying on a face on
the ground plane, with an edge touching the picture plane and all vertical faces
equally inclined to the picture plane. The station point is 50 mm in front of
the picture plane, 35 mm above the ground plane and lies in a central plane
which is 10 mm to the left of the center of the cube. (20)
