A line PQ is in the first quadrant. Its ends P and Q are 20 mm and 60 mm
in front of the V.P respectively. The distance between the end projectors is
75 mm. The line is inclined at 30
?
to the V.P, with its end in H.P. Draw
the projections of PQ and find its true length and the inclination with the
H.P. Also locate its H.T.
13
13. Draw the projections of a pentagonal plane, side 25 mm resting on the H.P
on one of its edges. The plane of the pentagon is inclined at 45
?
to the H.P
and the perpendicular drawn from the mid point of the resting edge makes
an angle of 30
?
with the V.P. 13
14. A square prism of base 40 mm is resting on HP with its base sides equally
inclined to both H.P and V.P and its axis inclined at 45
?
to H.P. It is cut by a
horizontal plane bisecting axis. Draw the true shape of the section, if the
axis is 80 mm. 13
15. Draw the projections of rhombus, having diagonals 120 mm and 60 mm
long, the smaller diagonal of which is parallel to both the principal planes,
while the other is inclined at 30
?
to H.P. 13
16. A vertical cone of base 60 mm dia and axis 70 mm long is penetrated by a
cylinder of 40 mm dia, such that the axis of the cylinder is parallel to the
axis of the cone, at a distance of 5 mm. Draw the projections, showing the
curves of intersection when (a) the plane containing the axes of the solids
is parallel to V.P and (b) when the plane containing the axes of the solids
is inclined at 60
?
to V.P. 13
17. A right circular cone of dia. 30 mm base and height 36 mm rests centrally
on top of a square block of 48 mm side and 22 mm thick. Draw the
isometric projection of the two solids. 13
