                                  PART – B     (5 x 12 = 60)

Answer All the Questions

11.   One end P of a line PQ is 15 mm above HP and 20 mm in front of VP while the other end Q is 50 mm above HP and 45 mm in front of VP. If the end projectors are at a distance of 60 mm, draw projections of the line. Find its true length and mark its traces.

(or)

12.   A hexagonal plate of side 30 mm is resting on one of its sides on VP and inclined at 40° to HP. Its surface is inclined at 35° to VP. Draw its projections.

13.   Draw the projections of a hexagonal prism of base side 20 mm   and axis length 50 mm when it rests on the ground on one of the       edges of the base and the axis inclined at 35° to the ground and        parallel to VP.

(or)

14.   A solid pentagonal pyramid of basic side 25 mm and 60 mm         height is suspended from a string attached to one corner of the         base of the pyramid. The string is held such that the apex of the         pyramid is just touching HP. The axis of the pyramid is parallel to VP. Draw the projections of the pyramid.

15.   A square prism of base side 30 mm and axis length 60 mm is resting on HP on its base with sides of base inclined at 30° to VP. It is cut by a plane inclined at 40° to HP and perpendicular to VP and is bisecting the axis. Draw the development of remaining portion of the solid.

(or)

16.   A cone of base diameter 50 mm and axis length 75 mm, resting on its base is cut by a plane inclined at 45° to HP and perpendicular to VP and bisecting the axis. Draw the sectional front view, sectional top view and true shape of the section.

17.   Draw the isomeric projection of a frustum of a pentagonal pyramid of bottom edge 40mm, top edge 26 mm and height 40         mm when resting on HP.

(or)

18.   A pentagonal prism of base side 25 mm and axis length 55 mm         rests on ground plane on one of its rectangular faces with its axis         inclined at 30° to picture plane. A corner of the base is touching         picture plane. The station point is 60 mm in front of picture plane         and lies in a central plane that bisects the axis. The station point         is 45 mm above ground plane. Draw perspective view of the         prism.

19.   Draw the three view of Fig-1

(or)

20.   Draw the pictorial view of the object shown in Fig-2
