Note: 1. Question Paper consists of two parts (Part-A and Part-B) 2. Answering the question in Part-A is compulsory
3. Answer any FOUR Questions from Part-B
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
PART ?A
1. a) Write a caption ?KNOWLEDGE IS LIGHT? using BIS standard lettering. (2M)
b) Show the operation of trisecting a right angle.
(2M)
c) A point P is 50 mm from both HP and VP. Draw its projections in at least two
positions. (2M)
d) A straight line AB 70mm long is in the VP and perpendicular to the HP its one
point A is contained by both the planes. Draw its projections. (2M)
e) A pentagonal plane with its side 30mm is perpendicular to the VP and its one side
inclined at 45
0
to the VP. Draw its projections. (2M)
f) Draw the projections of a cylinder base 40 mm diameter and axis 60 mm long,
with its axis perpendicular to VP and parallel to and 30 mm above HP. (2M)
g) Draw the isometric view of a semi-circle 50 mm diameter when its diameter is
vertical. (2M)
PART -B
2. a) Construct a heptagon using general method. (4M)
b) Draw a hypocycloid of a circle of 40 mm diameter which rolls inside another
circle of 200 mm diameter for one revolution and also draw a tangent and normal
at a point 90 mm from the centre of the base circle. (10M)
3. a) Draw a diagonal scale of R.F=1/75 to show metres, decimeters and centimeters
and to measure up to 6 metres. Mark a length of 3.75 metres on it. (6M)
b) A point A is 15mm above HP and 25mm in front of VP. Another point B is 40mm
below the HP and 50mm behind the VP. Draw the projections of these points
taking the distance between the end projectors as 50mm. Also find the length of
the line joining their plans and elevations. (8M)
4. a) The top view of a line GH, 90 mm long measures 65 mm its one end is 25mm
above the HP and 30mm in front the VP. (4M)
b) A line AB 70 mm long has its end A at 20 mm above the HP and 25 mm in front
of the VP. Its front view and top view measures 50 mm and 60 mm respectively.
Draw the projections of the line and determine its inclinations with the HP and the
VP. (10M)
