Answer any THREE Questions. Each question carries 14 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 traces and measure the

            distances of  the traces from the reference planes.                                                              (14)

 

Q.4      A hexagonal pyramid having base side 30 mm and axis 70 mm long has a corner of its

            base in the H.P. such that two of the base edges passing through the corner on which

            it rests are equally inclined to H.P.  Its axis is inclined at  to the H.P. and parallel

           to V.P.  Draw its projections.                                                                                            (14)

 

Q.5      Trace the locus of a point such that the difference between the distances of the point

            from two fixed points 40 mm apart is constant and is equal to 30mm.                                  (14)

 

Q.6      A cone having diameter of base 60 mm and axis 70 mm long is lying in H.P. on one of

            its generators with the axis parallel to V.P. It is cut by a horizontal section plane      

           12 mm above the H.P.  Draw the development of the lateral surface of the remaining

            portion of the cone.                                                                                                          (14)
