Recommendations for
II-Mid in Engineering drawing
1. A plot of 12m x 12m is
represented by 4cm2. Draw a scale to read upto 6 decameters.
Represent 45m on it.
2. The distance between Bombay and
Poona is 180km. A passenger train covers this distance in 6 hours. Construct a
plain scale to measure time upto a single minute. The R.F of the scale is
1/200000. Find the distance covered by the train in 36 minutes.
3.
The top view of a 75mm long line AB measures 65mm, while the length of its
front view is 50mm. Its one end A is in the H.P. and 12mm in front of the V.P.
Draw the projections of AB and determine its inclinations with the H.P. and the
V.P.
4. a) Draw the projections of the following points on the same ground line, keeping the projectors 25mm apart.
i) A,
in the H.P. and 20mm behind the V.P.
ii) B, 40mm above the H.P. and 25mm in
front of the V.P.
iii) C, in the V.P. and 40mm above the H.P.
iv) D, 25mm below the H.P. and 25mm behind
the V.P.
v) E, 15mm above the H.P. and 50mm behind the
V.P.
vi) F, 40mm below the H.P. and 25mm in front
of the V.P.
vii) G, in both the H.P. and the V.P.
b) A point A is situated in the
first quadrant. Its shortest distance from the intersection point of H.P., V.P.
and auxiliary plane is 60mm and it is equidistant from the principle planes.
Draw the projections of the point and determine its distance from the principle
planes.
5. The projectors of the ends of a
line AB are 5cm apart. The end A is 2cm above the H.P. and 3cm in front of the
V.P. The end B is 1cm below the H.P. and 4cm behind the V.P. Determine the true
length and its inclinations with the two planes.
6. A line PQ 100mm long, is
inclined at 300 to the H.P. and at 450 to the V.P. Its
mid-point is in the V.P. and 20mm above the H.P. Draw its projections, if its
end P is in the third quadrant and Q in the first quadrant
7. A semi-circular plate of 80mm
diameter, has its straight edge on V.P. and inclined at 300 to H.P.,
while the surface of the plate is inclined at 450 to V.P. Draw the
projections of the plate.
8.
A regular hexagon plane of 45mm side has a corner on H.P., and its surface is
inclined at 450 to H.P. Draw the projections, when the diagonal
through the corner. which is on H.P. makes 300 with V.P.
9.
Draw the projections of a rhombus, having diagonals 120mm and 60mm long, the
smaller diagonal of which is parallel to both the principle planes, while the
other is inclined at 300 to H.P.
10. Construct
a diagonal scale to read kilometers, Hecta meters and decameters and long
enough to measure upto 6 kilometers. When a line of length 1 cm represents a
distance of 0.5 kilometers, Calculate the R.F and indicate a distance of 2.45 kilometers on the
scale.
11.
A regular pentagon of 30mm side, is resting on one of its edges on H.P. which
is inclined at 450 to V.P. Its surface is inclined at 300
to H.P. Draw its projections.
