[Kiran Chandar]

As you want I am here providing you sample paper B.Tech Biotechnology Engneering Drawing course of Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR).

Sample paper :


1. (a) 2 points A and B are 100mm apart. A point C is 75mm from A and 60mm
from B. Draw an ellipse passing through A, B and C.
(b) The foci of an ellipse are 85mm apart and the minor axis is 60mm long.
Determine the length of the major axis and draw the ellipse by oblong method.
[8+8]

2. A circle of 40mm diameter rolls an a straight line without slipping . In the initial
position the diameter PQ of the circle is parallel to the line on which it rolls. Draw
the locus of the points P and Q for 1 complete revolution of the circle. [16]
3. (a) Point A is 20mm above H.P. and 30mm infront of V.P. Draw its front view
and top view.

(b) A pointMis 35mm above H.P. and 45 mm in front of V.P. Draw its projections.
(c) Draw the projections of a point A lying on H.P. and 30mm infront of V.P.
[4+8+4]

4. Draw the projections of a 70mm long straight line, in the subsequent positions:
(a) Parallel to and 40mm in front of the V.P and in the H.P.
(b) Perpendicular to the H.P, 20mm in front of the V.P and its 1 end 15mm
above the H.P.
(c) Perpendicular to the H.P, in the V.P. and its 1 end in the H.P.
(d) Inclined at 450 to the V.P, in the H.P. and its 1 end in the V.P. [4×4]

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]

7. Draw the isometric view of the block, 2 views of which are shown in figure 7.
(All dimensions are in mm). [16]

8. Draw the front view, top view and left side view of the object shown in figure 8.
(All dimensions are in mm). [16]
