N.B. (1) Question No. 1 is compulsory. Attempt any four questions out of remaining six questions.
(2) Answers to the questions should be grouped and written together.
(3) Use drawing sheets only for answering.
(4) Use your judgement for any unspecified dimensions.
(5) All dimensions in figure are in mm.
(6) Use first angle method of projection unless stated otherwise.
(7) Retain ail construction lines.

3. (a) PGR is a triangular lamina in the first quadrant as follows!:- ' j ' 10
(i) Corner P is on the H.P. and 50 mm in front of V.P.
(II) Corner Q and R on the V.P.
(iii) Elevation of lamina is equiiateral triangle of 65 mm sides and the elevation p'q' is inclined at 50 degree to xy, draw the projection of lamina and find its inclination with reference planes, also obtain its True Shape.
(b) The end M of line MN is 25 mm behind VP and 30 mm below HP, the distance between 10 end projectors of the line MN is 90 mm, the line is inclined at 30 degree to HP and 45 degree to VP, draw its projection when N is in second quadrant, find True Length and various angles.
4. A square pyramid with side of the base 30 mm and height 75 mm is placed with its base on the 20 H.P. A section plane perpendicular to front reference plane cuts the Pyramid such that the true shape of section is a pentagon of any size. Draw True Shape and inclination of section plane and also draw the projection of cut square pyramid when the base of pyramid is Inclined at 40 degree
to HP and the plane containing axis and the larger slant edge of cut Pyramid is inclined at 45 degree to VP. With the base of pyramid nearer to observer.
5. Figure shows the pictorial view of a machine-part. Draw to the full scale the following views'
(a) Sectional Front view along (A - A)
(b) Top view b
(c) Sectional side view (P - Q) 6 insert all dimension. 2
6. (a) Figure shows Front view and Left hand side view of an object. Draw isometric view using 10 natural scale taking O as origin.
(b) The views represent two discs which rolls along AB, both discs starts at the same point and 10 roll in the same direction, plot the curves for the movement of P and Q and state the perpendicular height of P above AB, when Q again coincides with the line AB.
7. (a) The development of the lateral surface of cone is a semi-circle of 90 mm radius, inscribe 14 largest possible Hexagon in a semi-circle. Draw the projection of solid when it rests on its base on H.P. and transfer the inscribe Hexagon in F.V. and TV.
(b) Draw two .views of the following 6
(i) Hexagonal head bolt 24)
(ii) Wing nut
(iii) Acme thread profile.
