13. A circular disc of dia. 40mm and negligible thickness rests on HP on its rim and
makes an angle of 45
0
to it. One of its diameters is inclined to VP at 30
?
. Draw its
projections keeping distance of the centre of the disc 40mm in front of the VP. (13)
14. A right regular pentagonal prism, side of base 30mm and height 75mm, rests on
one of its base corners on HP such that its long edge containing the corner is
inclined to the HP at 60o and the side of base, opposite the corner, inclined at
30
?
to VP. Draw its projections keeping the vertex towards the VP. (13)
15. A right regular rectangular pyramid of base 50 x 35 mm and height 70mm, rests
on its base in HP with one of its base sides parallel to VP. A section plane
perpendicular to the VP and inclined at 30
?
to the HP cuts the pyramid, bisecting
its axis. Develop the lateral surface of the truncated pyramid. (13)
16. A cylinder, diameter of base 60mm and 90mm long, resting on its base in HP, is
penerated completely by another cylinder of the same dimensions such that axes
are mutually perpendicular and symmetrical about one another. The axis of the
penetrating cylinder is 9mm in front of the axis of the vertical cylinder and is
parallel to both the H.P. and V.P. Draw the projection of the solids showing
curves of intersection. (13)
17. Draw the Isometric projection of two solids. A sphere is placed centrally on the
top of the truncated square pyramid of top face 30mm side and bottom face of
40mm side, when the height of the solid is 60mm. (13)
