Q.2 Fig. 1 on page 4 shows the isometric view of an object. Draw the following orthographic views. Take 1:1 scale

(i) Front view looking from ‘X’.

(ii) Side view looks from ‘Y’. (16+16 = 32)

SECTION C

Answer any THREE Questions. Each question carries 16 marks.

Q.3 The top view of a 60 mm straight line measures 40 mm while the length of its front view is 50 mm. Its one end A is in H.P. and other end B in V.P. Draw its projections and determine its inclination with H.P. and V.P. Show the trances and measure the distances of the traces from the reference planes. (16)

Q.4 Construct a diagonal scale of 3:200 showing meters, decimeters, centimeters and the measure up to 6 meters. Show a distance of 4.56 m on the scale. (16)

Q.5 A pentagonal prism 20 mm side of base and 50 mm high stands vertically with one of its rectangular faces parallel to V.P. and nearer to it. A section plane inclined at to H.P. and perpendicular to V.P. passes through one of the extreme corners of the top face of the prism. Develop the lower portion of the lateral surface of the prism so as to produce a one-piece development. (16)

Q.6 a. Draw the following rivet heads taking proportionate dimension. Take the nominal diameter = 24 mm.
