1. The distance between Vadodara and Surat is 130 Km. A train covers this distance
in 2.5 hours. Construct a plain scale to measure time up to a single minute. The
R.F of the scale is 1: 2,60,000. Show the distance covered by the train in 45 secs.
[16M]
2. The major axis of an ellipse is 160 mm long and the minor axis 90 mm long. Find
the foci and draw the ellipse by ‘Arcs of circles method’. Draw a tangent to the
ellipse at a point on it 25 mm above the major axis. [16M]
3. The front view of a line AB measures 65 mm and makes an angle of 45 degrees
with xy . A is in the H.P. and the V.T. of the line is 15 mm below the H.P. The
line is inclined at 30 degrees to the V.P. Draw the projections of AB and find its
true length and inclination with the H.P. Also locate its H.T. [16M]
4. A cone, diameter of base 50 mm and axis 65 mm long, is lying on the H.P. on one
of its generators with the axis parallel to the V.P. It is cut by a horizontal section
plane 12 mm above the ground. Draw its front view and sectional top view . [16M]
5. A vertical cylinder of 50 mm diameter and 75 mm long is penetrated by a horizontal
cylinder of 40 mm diameter and 75 mm long such that their axes bisect each other
at right angles. Draw the intersection curve. [16]
6. A sphere of diameter 40 mm rests centrally on the top of a square frustum, base
60 mm top 40 mm and height 75 mm. Draw the isometric view of the combination
of solids. [16]
7. Convert the isometric view of the picture shown in the figure7 below in to orthogonal
projection of all three views. [16M]
8. A circular lamina of 45 mm diameter lies on the ground plane and touches the
picture plane. The center plane passes through the center of the circle. The station
point is 70 mm in front of picture plane and 60 mm above the ground plane. Draw
the perspective view. [16M]
