B.Tech I Year I Semester (R15) Supplementary Examinations June/July 2019
ENGINEERING DRAWING
(Computer Science & Engineering)

Time: 3 hours Max. Marks: 70

(Answer all five units, 05 X 14 = 70 Marks)

*****

UNIT ? I

1 To draw rectangular hyperbola given the position of point p on it, 40 mm and 20 mm from the
asymptotes.
OR
2 Draw a cycloid given the diameter of a rolling circle as 40 mm and also draw normal and tangent at
any point on the curve.

UNIT ? II

3 Construct a diagonal scale of RF = 1/32 showing yards, feet and inches and to measure up to
4 yards.
OR
4 (a) Two points A and B are in the HP. The point A is 30 mm in front of the VP. While B is behind the
VP. 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 VP.
(b) A line AB 55 mm long makes an angle of 30? to HP and 45? to VP. The end A is 12 mm in front of
VP and 15 mm above HP. Draw the projection of the line.

UNIT ? III

5 A hexagonal lamina of 20 mm side rests on one of its corners on the HP. The diagonal passing
through this corner is inclined at 45? to HP. The lamina is then rotated through 90? such that the top
view of this diagonal is perpendicular to the VP and the surface is still inclined at 45? to the HP.
Draw the projections of the lamina.
OR
6 A thin rectangular plate of sides 50 mm x 25 mm has its shorter side in the HP and inclined at an
angle of 30? to the VP. Project its front view when its top view is a perfect square of 25 mm side.

UNIT ? IV

7 A pentagonal prism side of base 25 mm and axis 50 mm long rests with one of its edges on HP
such that the base containing that edge makes an angle of 30? to HP and its axis is parallel to VP.
Draw its projections.
OR
8 A cone base 55 mm diameter and height 75 mm rests with its base on HP. Draw its projections and
draw the development of the lateral surfaces of the cone.
