Unit-III
5. A
pentagonal pyramid with 25 mm side base and 65 mm height has one of its slant
faces on the horizontal plane and the edge of the base contained by that slant
face makes an angle of 25° to the V.P. Draw the projections of the pyramid.
14 Marks
Refer Example 9.31, Page 9.38 of EG - Basant Agrawal,
TMH.
OR
6. A
square plate of 45 mm side and 40 mm thick is nailed centrally to right square
prism of 30 mm side and height 60 mm such that their axes coincide. Draw the
projections when axis of the combined solid is parallel V.P. to inclined at 30° to
H.P. The two base edges of square plate are parallel to V.P. and edges of prism
are parallel to square plate and combination is resting on one of the base
edges of square plate. 14 Marks
One should know Example 9.5, Page 9.11 of EG - Basant Agrawal,
TMH.
Unit-IV
7. A
pentagonal prism side of base 30 mm and axis 60 mm long lies with one of its
rectangular faces on H.P. and its axis is inclined at 30° to V.P. A section
plane perpendicular to H.P. and parallel to V.P. cuts the prism into two
halves. Obtain its top and sectional front view. 14 Marks

8. A
square pyramid side of base 30 mm and axis length 45 mm is resting on its base
on H.P. with sides of base equally inclined to V.P. A circular hole of diameter
20 mm is drilled through the pyramid so that axis of the hole is perpendicular
to V.P. and parallel to H.P. and intersecting the axis of the pyramid at 12.5
mm above the base. Develop the pyramid. 14 Marks
