Unit-I
1. a) Draw
a diagonal scale of R.F = 3:100 showing metres, decimetres and centimetres and
to measure upto 5 metre. Show the length of 3.69 m on it. 7 Marks
Refer Example 2.12, Page
2.12 of EG - Basant Agrawal, TMH.
1. b) A
link 225 mm long swings on a pivot O from its vertical position of rest to the
right through an angle of 75° and returns to its initial position at uniform
velocity. During that period, a point P moving at uniform speed along the
centre line of the link from a point at a distance of 25 mm from O reaches the
end of the link. Draw the locus of the point P. 7 Marks

2. a) Draw
a straight line AB of any length. Mark a point F 65 mm from AB. Trace the paths
of a point P moving in such a way that ratio of its distance from point F to its
distance from AB is 3:2. Plot 8 points. Name the curve and draw a normal and
tangent at a point 50 mm from F. 7 Marks

on a point of the base on H.P. with its axis inclined at 45° to H.P. and
parallel to V.P. 7 Marks

6. A
hexagonal headed rod of 25 mm diameter has its cylindrical portion 60 mm long.
The side of the hexagonal head is 25 mm having a thickness of 25 mm. Draw the
projection of the rod when its lying on H.P on one of its edges of the head and
with axis inclined at 30° to H.P. 14 Marks
Unit-IV
7. A
pentagonal prism of side of base 30 mm and axis 60 mm long rests with one of
its rectangular faces on H.P. with its axis inclined at 30° to V.P. A section
plane cuts the solid into two halves. Draw the projections of the solid. 14 Marks
Refer Example 10.7, Page 10.11 of EG - Basant
Agrawal, TMH.
OR
8. A
square pyramid side of base 30 mm and axis length 40 mm is resting on its base
on H.P. with sides of base equally inclined to V.P. A circular hole of diameter
20 mm is drilled through the pyramid so that axis of the hole is perpendicular
to V.P. and parallel to H.P. and intersecting the axis of the pyramid at 12.5
mm above the base. Draw the development of the pyramid.
