Assignment
Questions: III MID ENGINEERING DRAWING
1. A right circular cylinder, base
50 mm diameter and axis 60 mm long, is standing on HP on its base. It has a
square hole of size 25 in it. The axis of the hole bisects the axis of the
cylinder and is perpendicular to the VP. The faces of the square hole are
equally inclined with the HP. Draw its projections and develop lateral surface
of the cylinder.
- A right circular cone base 30 mm side and height 50 mm rests on its
base on H.P. It is cut by a section plane perpendicular to the V.P.,
inclined at 45º to the H.P. and bisecting the axis. Draw the projections
of the truncated cone and develop its lateral surface.
- A square pyramid, base 40 mm side and axis 65 mm long, has its base
on the HP and all the edges of the base equally inclined to the VP. It is
cut by a section plane, perpendicular to the VP, inclined at 45º to the HP
and bisecting the axis. Draw its sectional top view, sectional side view
and true shape of the section. Also draw its development.
- A pentagonal pyramid , base 30mm side and axis 60 mm long is lying
on one of its triangular faces on the HP with the axis parallel to the VP.
A vertical section plane, whose HT bisects the top view of the axis and
makes an angle of 30º with the reference line, cuts the pyramid removing
its top part. Draw the top view, sectional front view and true shape of
the section and development of the surface of the remaining portion of the
pyramid.
- A vertical cylinder of 60 mm
diameter is penetrated by another
cylinder of 40mm diameter the axis of which is parallel to both HP and VP.
The two axes are 9 mm apart. Draw the projection showing curves of
intersection.
- A cone of base 60 mm diameter and axis 70 mm long stands vertically
with its base on H.P. It is penetrated by a horizontal cylinder of 26 mm
diameter. The axis of the cylinder is parallel to V.P., 20 mm above the
base and 5 mm in front of the axis of the cone. Draw the projections of
solids showing the curves of intersection.
- A frustum of hexagonal pyramid, base 40mm side, top 20 mm side and
height 50 mm rests with its base on the Ground Plane such that one of the
edges of its base is touching the PP. The station point is 40 mm infront
of PP, 75 mm above the GP and lies
in a central plane which passes through the centre of the frustum. Draw
the perspective view.
- A hexagonal plane of 25 mm side stands vertically on the ground
plane and inclined at 50° to the picture plane. The
corner nearest to picture plane is 20 mm behind it. The station point is 45
mm in front of the picture plane, 50 mm above the ground plane and lies in
central plane which passes through the centre of the plane. Draw the
perspective view of the plane.
- Draw the Isometric views of the following figures.
- Draw the three orthographic views of the following figures ( Front,
Top & Side Views )

1. Draw the projections of the
following points on the same ground line, keeping the projectors 20mm apart.
(a) Point A in the VP and 40mm above
HP.
(b) Point B 25mm below the HP and 25mm
behind the VP.
(c) Point C 15mm above the HP and 50mm
behind the VP.
(d) Point D 40mm below the HP and 25mm
infront of the VP.
2.
A line AB of 100 mm length is inclined 300 to HP and 450
to VP. The point A is 15mm above HP and
20mm infront of VP. Draw the projections of the line.
3. A room measures 8m long, 5m
wide and 4m high. An electric bulb hangs
in the center of the ceiling and 1m below it. A thin straight wire connects the
bulb to switch kept in one of a corner of the room and 1.25m above the floor.
Draw the projections of the wire, also determine its true length and slope with
the floor.
4. a). A 90 mm long line is
parallel to and 25 mm in front of the V.P. It’s one end is in the H.P. while
the other is 50 mm above the H.P. Draw it’s projections and find it’s
inclination with the H.P.
b). The top view of a 75 mm long
line measures 55 mm. The line is in the V.P. It’s one end being 25 mm above the
H.P. Draw it’s projections.
5). A semi circular
plate of 80mm diameter has its straight edge in the V.P. and inclined at 600
to the H.P, the surface of the plate makes an angle of 300 with the
V.P. Draw its projections.
6). A regular pentagon of 30mm side, has one of its corners on V.P. and its
surface is inclined at 600 to the V.P. the edge, opposite to the
corner on V.P. makes an angle of 450 with H.P. Draw the projections
of the plane.
7). A regular hexagon of 40mm has a corner in the H.P. Its surface is inclined at
450 to the H.P. and the top view of the diagonal through the corner
which is in the H.P. makes an angle of 600 in the V.P. Draw its
projections.
