ENGINEERING DRAWING(NOV/DEC 2008-09)

Time--Four Hours Maximum Marks--80“Please check whether you have got the right question paper”N. B. :-(i) Question Numbers 1 and 6 are compulsory. (ii) Solve two questions each from remaining questions of Section A and

Section B. (iii) Assume suitable additional data if necessary, and mention it clearly.

Section AQ.1. The projections of the ends of a line AB are on the same

projector. The end A is 30 mm below H.P. and 15 mm behind V.P. The end B is 35 mm above H.P. and 40 mm in front of V.P. Determine its true length, the traces and the inclinations with the reference planes.

(14)

Q.2. A regular Hexagon ABCDEF of 30 mm side is the front view of a plate when its surface is inclined at 300 to the V.P. Draw the projections when its side AB is in V.P. and inclined at 450

to the H.P.

(13)

Q.3. A pentagonal pyramid, side of base 25 mm and height 60 mm has one of its slant (triangular) faces on the H.P. and the edge of base contained by that slant edge makes an angle 30 degree to the V.P. Draw its projections.

(13)

Q.4. Three spheres of 40 mm diameter are placed on ground touching each other, with line joining centers of any two parallel to V.P. A fourth sphere of diameter 50 mm is placed centrally over these spheres, determine the height of centre of the fourth sphere by means of projections of the arrangement.

(13)

Q.5. A cone diameter of base 60 mm and height 70 mm is lying on the ground with on of the generators its axis parallel to V.P. It is cut by a vertical section plane inclined at 400 to the V.P. Draw the sectional front view, top view and true shape of section.

(13)

Section BQ.6. Figure 1, shows an isometric view of an object. Draw the

following views. i) Front view in direction of arrow, ii) Top view, and iii) Side view from right.

Q.7. Figure 2. Shows front view of a cut cylinder with base diameter 60 mm. with its axis parallel to V.P. and perpendicular to H. P. Draw the development of the lateral surface of the part P of the cylinder.
