PART – B
Answer ALL the Questions
(5 x 12 = 60)
11. Fig. 1 shows the pictorial view of the guide bracket for a
horizontal spindle. Draw the three orthographic views.
(or)
12. Draw the front view, top view, and right side view of the object
shown in fig.2.
13. A cone of base diameter 60mm and altitude 70mm rests in its
base on the HP. It is cut by a plane perpendicular to both HP and
VP and passing through the cone 10mm to the left of the axis.
Draw the development of the lateral surface of the right portion
of the cut cone.
14. A horizontal cylinder of diameter 40mm penetrates into a vertical
cylinder of diameter 60mm. The axis of the cylinders intersects
at right angles. Draw the curves of intersection when the axis of
the horizontal cylinder is parallel to the VP.
15. A pentagonal pyramid, 25 mm edge of base and 60 mm height
stands on HP such that an edge of the base is perpendicular to VP
and nearer to it. A sectional plane perpendicular to VP and
inclined at 30 to HP cuts the pyramid passing through a point
on the axis at a height of 35 mm from the base. Draw the
isometric view of the truncated pyramid, showing the cut surface.
(or)
16. A cylinder of 60mm diameter and 70mm height stands on HP-A
section plane perpendicular to VP and inclined at 50 to HP, cuts
the cylinder and passes through a point on the axis at a height of
50mm above the base. Draw the isometric view of the truncated
portion of the cylinder.
17. A hexagonal prism of base side 20mm and height 50 mm rests on
the ground plane on one of its rectangular faces with its axis
inclined at 30 to the picture plane. A corner of the base is
touching the picture plane. The station point is 60mm in front of
the picture plane and lies in a central plane that bisects the axis.
The station point is 40mm above the ground plane. Draw the
perspective view of the prism.
(or)
18. A cube of 35mm edge lies with a face on the ground and an edge
on the picture plane. All the vertical faces are equally inclined to
the picture plane. The station point is 80mm in front of the PP
and 60mm from the ground. The edge of the cube in contact with
the picture plane is situated 10mm to the right of the station
point. Draw the perspective of the cube.
19. The plinth of a computer office measures 15 x 10m. Provide a
room for the EDP manager and a room for technical supervisors.
Draw the plan and sectional elevation of the office if the ceiling
height is 3.3 meters. Assume any other data required.
(or)
20. Draw the plan and elevation of a simple storied residential
building of plinth area 100m2. Thickness of the wall is 200mm.
Adopt a suitable scale.
