9. A right regular pentagonal prism, edge of base 25 mm and height 70 mm resting

on its base on HP, is cut by a section plane inclined to HP at 40? and meeting the

axis at a distance of 20. mm from its top end. Develop the outside surface of the

cut prism. 4

10. A cube of 25 mm edge is placed centrally on top of a cylindrical block of dia 50 mm

and 20 mm height. Draw the isometric drawing of the solids. 4

PART? B (65 Marks)

11. Draw a branch of hyperbola when the distance of its focus from the directrix is

50 mm and its eccentricity is 3/2. Also, draw a tangent and a normal to the curve

at a point P on it. 13

12. A line AB is 70 mm long. It is inclined at 45? to HP. Its front view at' measures 50

mm. The end A is 15 mm above HP and 20 mm in front of VP. The end B is in the

first quadrant. Draw the Projections of the line. Determine its traces and its

inclination to VP. 13

13. An equilateral triangular plate is of 50 mm side with negligible thickness. Draw the

front and top views of the plate when its plane is vertical and inclined at 35? to VP.

inclined to the HP at 55? and the side of base, opposite to the corner, inclined at

30? to the VP. Draw its projections keeping the vertex towards the VP. 13

15. A right regular pentagonal pyramid, edge of base 30 mm and 65 mm height, is

lying on one of its triangular faces on ground plane such that its axis is parallel to

VP. A Section plane perpendicular to the VP and inclined to the HP at 60? cuts the

pyramid meeting its axis at a distance of 30 mm from the vertex. Draw its

sectional top view and true shape of the section. 13

16. A right circular cylinder, base 55 mm dia and 100 mm height, resting on its base in

penetrating cylinder is inclined to HP at 40?, is parallel to VP and intersect the

axis of the vertical cylinder at a distance of 20 mm in front of its base (i.e. from its

base). Draw the projections of the two cylinders showing the curves of

intersection, Assume any suitable length of penetrating cylinder. 13

17. a) The distance between station A and B is 200 km. A vehicle covers this distance

R.F. of the scale is 1/200000. Indicate on this scale the distance covered by

the vehicle in 36 minutes. 8
