ICSE Class 10 Question Paper 2020 for Technical Drawinign 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.

Draw the Front View, Top View, Right Hand Side View and development of the [16]
lateral surface of a right hexagonal pyramid whose axis is perpendicular to the
horizontal plane (H.P.) and parallel to the vertical plane (V.P.). One side of its base
is inclined at 45° to the V.P.

Use the THIRD ANGLE METHOD of projection.

Given: Side of the base = 30mm

Length of the axis = 75mm.

This paper consists of 6 printed pages.

Question 2.

Refer to Figure 1 given below. [16]
Copy the given template.
(Insert any 6 dimensions.)

Question 3.

Given: R. F. = 1: 500. [16]
Construct a PLAIN SCALE to measure the length upto 60 metres.
Taking the measurements from the scale constructed, draw a neat scale diagram of a
jogging track shown in the Figure 2 given below.

Show the data and the working neatly.

Question 4.
(a) Construct a Parabola by TANGENT METHOD. [10]
Given: - Base =140 mm and Length of axis = 85 mm.

(b) Draw a transverse common tangent to two circles of radii 50 mm and 35 mm [6]
with their centres 115 mm apart.

Question 5.

Refer to Figure 3 given below. It shows the Front View (F.V.) and the Left Hand Side [16]
View (L. H. S.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.
(Do not insert any dimensions.)

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

Question 6.
Refer to Figure 4 given below. It shows the Front View (F.V.) and the Top View [26]
(T. V.) of an object in the FIRST ANGLE METHOD of projection.
Draw its ISOMETRIC VIEW.
[Use scale 1 : 1]

Question 7.
Refer to Figure 5 given below. It shows the Front View (F.V.) and the Top View [26]
(T.V.) of a right square pyramid in FIRST ANGLE METHOD of projection. Its axis
is perpendicular to the horizontal plane (H.P.) and parallel to the vertical plane (V.P.).
All sides of the base are equally inclined at 45° to the V.P. It is cut by a section plane
whose horizontal trace (H.T.) makes an angle of 45o with the X – Y line. Using FIRST
ANGLE METHOD of projection draw the:
(a) Sectional Front View
(b) Top View
(c) Sectional L.H.S.V.
(d) Development of the lateral surface.
Given: Side of base = 40 mm
Length of axis = 70 mm

Question 8.

Refer to Figure 6 given below. [26]

Using the FIRST ANGLE METHOD of projection, draw the:

(a) Half Sectional Front View [Section along A–B-C]

(b) Top View

(c) Left Hand Side View.

(Insert any 6 dimensions.)
