Answer any FIVE Questions
1. (a) Construct an ellipse when a pair of conjugate diameters AB and CD are equal
to 110mm and 50mm respectively. The angle between the conjugate diameters
is 700
(b) Construct a parabola with in a parallelogram of sides 110mm × 50mm. One
of the included angle between the sides is 700.
2.A circle of 115 mm diameter rolls on another circle of 75mm diameter with internal
contact. Draw the locus of a point on the circumference of rolling circle for its one
complete revolution.
3.(a) A point A is 20mm above H.P. and in the first quadrant. Its shortest distance
from the reference line XY is 40mm. Draw the projections of the point and
determine its distance from V.P.
(b) A point at 25mm above the reference line x y is the front view of two points A
and B. The top view of A is 40mm behind V.P. and the top view of B is 50mm
in front of V.P. Draw the projections of the points and state their positions
relative to the planes of projection and the quadrants in which they lie
4. A line CD 80mm long is inclined at an angle of 300 to H.P. and 450 to V.P. The
point C is 20mm above H.P. and 30mm in front of V.P. Draw the projections of
the straight line
5. Draw the projections of a regular hexagon of 25mm side, having one of its sides
in the H.P. and inclined at 600 to the V.P, and its surface making an angle of 450
with the H.P.
6. A regular pentagonal pyramid, base 30mm side and height 80mm rests on one edge
of its base on the ground so that the highest point in the base is 30 mm above the
ground. Draw its projection when the axis is parallel to the V.P.
7.Draw the isometric view of a Door-Steps having three steps of 22cm tread and 15cm
rise. The steps measure 75cm widthwise.
8.Draw the front view, top view and left side views of V- block as shown in figure.8.
