Q.2 The details of a Plummer block are shown in Fig.1. Draw:
(i) Front view with left half in section.
(ii) Left side view.
Show overall dimensions. Print the title and draw the projection symbol. (25+10+5+1+1=42) (10)
SECTION C
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)
