PART – B                       (5 x 12 = 60)

Answer All the Questions

11.   Draw a parabola given the distance of the focus from the directrix as 70mm.

(or)

12.   A line PF 65mm long has its end P, 15mm above the HP and 15mm in front of the VP. It is inclined at 55° to the HP and 35° to the VP. Draw its projections.

       

13.   Draw the projections of a cube of side 40mm when it rests on one of its corners with a diagonal of the solid vertical.

(or)

14.   A pentagonal pyramid of base edge 40mm and altitude 70mm rests on one of its base edges on the HP with its axis inclined at 30° to the HP and parallel to the V.P. Draw its projections.

15.   A cylinder of base diameter 40mm and height 50mm rests with its base on the HP. It is cut by a section plane perpendicular to the VP and inclined at 50° to the HP. The cutting plane meets the axis at a distance of 15mm from the top. Draw the front view, sectional top view and the true shape of the section.

(or)

16.   A cone of base diameter 60mm and altitude 70mm rests with its base on the HP. It is cut by a section plane perpendicular to both the VP and the HP and passing through the cone 10mm to the left of the axis of the cone. Draw the development of the lateral surface of the right portion of the cut cone.

17.   Draw the isometric view of the frustum of a hexagonal pyramid when it is resting with its base on the HP with two sides of the base parallel to the VP. The side of the base is 20mm and that of the top is 8mm. The height of the frustum is 55mm.

(or)

18.   A Square prism of base 25mm x 25mm and height 40mm rests on the GP with its edges of the base making 45° with PP. The corner nearest to the PP is 25mm to the right of the station point and 25mm behind the PP. The station point is 55mm above the GP and 70mm in front of PP. Draw the perspective view of the square prism.

19.   Draw the Top view Front view, right side view and left side view of the object shown in the figure

(or)

20.   Convert the Orthographic Projection shown below into isometric drawing.
