B.Tech I Year II Semester (R15) Regular & Supplementary Examinations May/June 2019
ENGINEERING DRAWING
(Common to ECE, EIE & FT)
Time: 3 hours Max. Marks: 70
(Answer all five units, 05 X 14 = 70 Marks)
*****
UNIT ? I
1 Construct an ellipse, with distance of the focus from the directrix as 50 mm and eccentricity as 2/3.
Also draw normal and tangent to the curve at a point 60 mm from the directrix.
OR
2 Show by means of drawing that when the diameter of the directing circle is twice that of the
generating circle, the hypocycloid is a straight line. Take the generating circle diameter equal to
50 mm.
UNIT ? II
3 Draw a scale of full size, showing 1/100 inch and to measure up to 5 inches. Mark a length of
3.45 inches and 7.62 cm on the scale.
OR
4 (a) Two points A and B are in the H.P. The point A is 30 mm in front of the V.P., while B is behind the
V.P. The distance between their projectors is 75 mm and the line joining their top views makes an
angle of 45? with xy. Find the distance of the point B from the V.P.
(b) A point D is 50 mm from both H.P and V.P. Draw its projections in all possible positions.
UNIT ? III
5 The projectors of the ends of a line AB are 50 mm apart. The end A is 20 mm above the H.P and
30 mm in front of the V.P. The end B is 10 mm below the H.P and 4 cm behind the V.P. Determine
true length and traces of AB and its inclinations with the two planes.
OR
6 Determine the true shape of the figure, the top view of which is a regular pentagon of
30 mm side, having one side inclined at 30? to xy and whose front view is a straight line making an
angle of 45? with xy. Use auxiliary plane method.
UNIT ? IV
7 A square prism, base 25 mm side and height 50 mm has its axis inclined at 45? to H.P and has an
edge of its base, on H.P and inclined at 30? to the V.P. Draw its projections.
OR
8 A hexagonal pyramid of side 30 mm and axis height 70 mm is resting on H.P being one side of the
base parallel to the V.P. Draw the development of the lateral surface of the solid.
