Answer any FIVE Questions
1. The foci of an ellipse are 90mm apart and the minor axis is 65mm long. Determine
the length of the major axis and draw half of the ellipse by concentric circle method
and other half by oblong method. Draw a curve parallel to the ellipse and 25mm
away from it.
2.Draw a hypocycloid of a circle of 45mm diameter which rolls inside another circle
of 200 mm diameter for one revolution. Draw a tangent and normal at any point
on it.
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.
(c) Two points A and B are in the H.P. The point A is 30mm in front of the V.P.,
while B is behind the V.P. The distance between their projectors is 75mm
and the line joining their top views makes an angle of 450 with xy. Find the
distance of the point B form the V.P.
4. Draw the projections of a line AB, 90mm long, its mid point M being 50mm above
the H.P. and 40mm in front of the V.P. The end A is 20mm above the H.P. and
10mm in front of the V.P. Show the inclinations of the line with the H.P. and the
V.P.
5. Draw the projections of a circle of 60 mm diameter, resting on V.P. on a point on
the circumference. The plane is inclined at 450 to V.P. and perpendicular to H.P.
The centre of the plane is 40mm above H.P.
6. (a) Draw the projections of a triangular prism, base 40 mm side and axis 50 mm
long, resting on one of its bases on the H.P. with a vertical face perpendicular
to the V.P.
(b) A cube of 50mm long edges is resting on the H.P. with its Vertical faces equally
inclined to the V.P. Draw its projections.
((c) A triangular prism, base 40 mm side and height 65 mm is resting on the H.P.
on one of its rectangular faces with the axis parallel to the V.P. Draw its
projections.
7.(a) Draw the isometric view of a square prism, with side of base 40mm and length
of axis 70mm, when its axis is i. vertical and
ii. horizontal.
(b) Figure 7b shows the front view of a sphere, resting centrally on the top of a
square block. Draw the isometric projection of the arrangement all dimensions
are in mm.
8. Draw the following views of the block shown in figure 8. All dimensions are in mm.
- Front View.
- Top view
- Both side views.
