Answer all questions.

Each full question carries 20 marks.

Retain all the construction lines. Drawing sheets will be supplied.

1. A stone is thrown from the top of building of 6.m. height to just pass over a tree of

    9.m. height. The distance between the building and tree is 3m. Find the distance to the

    point where the stone hits the ground. Assume parabolic path  for the stone.

Or

2. Draw a left handed involute of a hexagon of 20 mm side and draw a tangent and a

    normal at any point P on the involute.

3. A square lamina ABCD of 30 mm. side rests on the corner C such that the diagonal AC

   appears as at 300 to the VP in the top view. The two sides BC and CD containing the

   corner C make equal inclination with the HP. The surface of the lamina makes 450 with

   HP. Draw its projections.

Or

4. Draw the projections of a straight line PQ,100 mm. long , inclined at 450 to HP and 300

    to VP. The end P is in HP and the end Q is in VP. Find the shortest distance between

    the  line PQ and the line of intersection of HP and VP.

5. A regular pentagonal  pyramid side of base 40 mm. and axis 80 mm. is freely

   suspended from a corner of its base. Draw the projection of the pyramid when the axis

    parallel to  the profile plane. Find inclination of the axis with HP and VP.

Or

6. A hexagonal pyramid edge of base 40 mm and axis 80 mm. rests with its base on HP

    and an edge of the base inclined at 300 to VP. A section plane inclined at 400  to VP

    and  perpendicular to HP passes through the pyramid at a distance of 8 mm. from the

    axis and infront of it. Draw the sectional front view and the true shape of section.  

7.  A frustum of a cone base 60 mm. diameter , top 36 mm diameter and height

    70 mm is standing vertically on HP. A hole of 30 mm diameter is drilled through the

    cone such that the axis of the circular hole is perpendicular to VP and bisects the

    height of the frustum. Draw the development of the lateral surface of the frustum of  

    the cone with the hole.

Or

8. A hexagonal based prism of base edge 30 mm. and axis height 80 mm is resting with

   one of its rectangular faces on HP. A cylinder of diameter of 30 mm and height 40 mm.

   rests  centrally with its base on the top rectangular face of the prism. Draw the isometric

   projection of the combination  of solids.

9.  A rectangular prism of base 30 mm * 50 mm and height 30 mm is resting on its

     base on the ground with a vertical touching PP. One of the  vertical face containing

   this  edge makes 400 with the PP. The edge touching the PP is 20 mm to the left of the

   observer and the station point is 70 mm from the PP. Take the horizon plane 80 mm

   above the ground. Draw the perspective view of the object.

Or

 

10. A vertical square prism ,base 50mm side , has its faces equally inclined to  VP.

      It is completely penetrated by another square prism of base 30 mm. side ,the axis of

      which is parallel to both VP and HP and is 6 mm away from the axis of the vertical

      prism. The faces of the horizontal prism are equally inclined to the VP. Draw the

      projections of the solids showing lines of intersection. Assume length of both prisms

      to be 100 mm .
