Answer any THREE Questions. Each question carries 14 marks.

 

 Q.3     A regular hexagonal lamina of 25 mm side has a corner in the H.P. Its surface is

            inclined at 30º with H.P. and the diagonal through the corner on which it rests on

            H.P., makes an angle of 45º with the V.P. Draw its projection.                                           (14)

 

Q.4      Draw the projection of a square pyramid with base side 30mm and axis 60 mm

            long resting on one of its edge of base in the H.P. with its axis inclined at 60º to

            V.P. and 25º to H.P.                                                                                                        (14)

 

Q.5      A right circular cone of base diameter 50 mm and axial height 70 mm. is resting on its

           base in the H.P. It is cut by a plane peependicular to V.P. and at 60º to H.P. through

           the middle of the axis. Draw the sectional plan and development of the lateral surface

           of the truncated cone.                                                                                                         (14)

 

Q.6      Draw an epicycloid generated by a rolling circle of diameter 30 mm. and the

          directing circle of diameter 150 mm.                                                                                    (14)

 

Q.7      Draw two views of a double riveted butt joint, chain riveting with two cover plates for

           joining two plates 9 mm thick. Show main dimensions.                                                        (14)
