ENGINEERING GRAPHICS
Time: 3 Hours (COMMON TO ALL BRANCHES) Max. Marks: 100
Note: 1. Answer three full questions 2. Use A4 sheets supplied.
3. Draw to actual scale 4. Missing data, if any, may be assumed suitably.
1. A line PQ 85mm long has its end P10mm above HP and 15mm in
front of the VP. The top view and front view of line PQ are 75 mm
and 80mm respectively. Draw the projections. Also determine the
true and apparent inclinations of the line.

1. A square plate of 40mm side rests on HP such that one of the
diagonals is inclined at 300 to HP and 450 to VP. Draw its
projections.
25 Marks
2. A hexagonal prism 25 mm sides of base and 50 mm axis length
rests on HP on one of its edges. Draw the projections of the prism
when the axis is inclined to HP at 450 and appears to be inclined to
VP at 450.

3. A square pyramid of 25 mm base edge and 50 mm height rests with
its base on HP with all of its base edges equally inclined to VP. It is
cut by a plane perpendicular to VP and inclined to HP at 600,
passing through the extreme right corner of the base. Draw the
development of the lateral surface of the pyramid.
