ICSE Class 10 Question Paper 2019 for Technical Drawing Applications

TECHNICAL DRAWING APPLICATIONS

(Three hours)

Answers to this paper must be written neatly on the paper provided separately.

You will not be allowed to draw/write during the first 15 minutes.

This time is to be spent in reading the question paper.

The time given at the head of the paper is the time allowed for writing the answers.

Attempt five questions in all.

You must attempt three questions from Section A and two questions from Section B

Each section should be answered on a separate paper.

All questions must be answered in full scale.

All construction lines must be shown.

All dimensions are in millimeters unless specified otherwise.

The intended marks for question or parts of questions are given in brackets [ ].

SECTION A (48 Marks)
Answer any three questions from this section.

Question 1.

In a diagram a line measuring 12 mm was marked as 4 cm. Calculate the R.F. [16]

Using the same R.F. construct a DIAGONAL SCALE long enough to measure
3.61 dm.

Taking the measurement from the scale constructed, draw an equilateral triangle of

side 3.61 dm.

Draw the incircle of this triangle.

Show the data and the working neatly.

This paper consists of 8 printed pages.

Question 2.

Construct an ELLIPSE by the OBLONG METHOD. [16]

Given : Major Axis = 150 mm

Minor Axis = 100 mm.

Question 3.

(a) Draw a square of side 100 mm. Construct four equal circles inside the square [6]
so that each circle touches one side of the square and two other equal circles
externally.

(b) Refer to Figure 1 given below. It shows the Front View (F.V.) and the Top [10]
View (T.V.) of a right circular cylinder in the FIRST ANGLE METHOD of
projection. Its axis is perpendicular to the horizontal plane and parallel to the
vertical plane. Copy the given figure and draw its AUXILIARY TOP VIEW.

The auxiliary plane X1Y1 is shown in the figure.

Given: Diameter of the base = 70 mm

Length of axis = 75 mm.

Question 4.
Refer to Figure 2 given below. It shows the Front View (F.V.) and the Top View [16]
(T.V.) of an object in the FIRST ANGLE METHOD of projection. Draw the
OBLIQUE VIEW when the receding axis is inclined at 45° to the horizontal.

SECTION B (52 Marks)
Answer any two questions from this Section.

Question 6.
(a) Refer to Figure 4 given below. It shows the Front View (F.V.) and the Top [12]
View (T.V.) of a right hexagonal prism in the THIRD ANGLE METHOD of
projection.

Its axis is perpendicular to the horizontal plane (H.P.) and parallel to the
vertical plane (V.P.). Two sides of its base are perpendicular to the V.P. The
prism is cut by a cutting plane inclined at 60° to the H.P. and perpendicular to
the V.P. The Vertical Trace (V.T.) of the cutting plane is shown in the figure.
Draw the:
(i) Front View
(ii) Sectional Top View
(iii) Development of the Lateral Surface of the remaining part P of the Prism.

Given: Side of the base = 30 mm

Length of Axis = 70 mm.

(b) Refer to Figure 5 given below. It shows the Front View (F.V.) and the Top [14]
View (T.V.) of a right square pyramid in the THIRD ANGLE METHOD of
projection.

Its axis is perpendicular to the horizontal plane (H.P.) and parallel to the
vertical plane (V.P.). The pyramid is cut by a cutting plane inclined at 30 ° to
the H.P. and perpendicular to the V.P. The Vertical Trace (V.T.) of the cutting
plane is shown in the figure. Draw the:

(i) Front View

(ii) Sectional Top View

(iii) Sectional Left Hand Side View

Given: Side of the base = 40 mm

Length of Axis = 75 mm.

Question 8.

Refer to Figure 7 given below. Using the FIRST ANGLE METHOD of projection, [26]
draw the:

(i) Full Sectional Front View [section along A - A]

(ii) Top View

(iii) Left Hand Side View.

(Insert any 6 dimensions.)
