Answer any THREE Questions. Each question carries 16 marks.

 

 

 Q.3          A straight line AB has its ends A and B, 45 mm and 20 mm infront of VP respectively. The end projectors of the line when measured parallel to the line of intersection of planes of projection are 50 mm apart. The HT of the line is 10 mm infront of VP. The line is inclined at 35o to HP.  Draw the projection of the line and locate VT. Find the distance of VT of the line from HP and the inclination of the line with VP.  (16)

 

Q.4            A right cone of base diameter 50 mm and length of the axis 70 mm is resting with its base on HP.  A cutting plane perpendicular to VP and inclined at  to H.P. passes through a point on the axis of the cone, 30 mm above the base.  Draw the sectional top view, front view and true shape of the section. (16)

 

Q.5            Construct a diagonal scale of representative fraction .  It should be long enough to measure 100 metres.  Show a distance of 64.4 metres on the scale.                                                               (16)                                                                                                                                                                   (16)
