TECHNICAL DRAWING APPLICATIONS
(Three hours)
Answers to this paper must be written 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 this 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 millimetres unless specified otherwise.
The intended marks for questions or parts of questions are given in brackets [ ].
SECTION A (48 Marks)
Answer any three questions from this Section.
Question 1
Construct a Parabola of 120 mm base and axis of 80 mm by the Tangent method. [16]
Question 2.
(a) Construct a parallelogram ABCD having its perimeter = 240 mm.
AB : BC = 5 : 3 and angle BAD = 60°. On side AD draw an equilateral triangle ADE. [8]
(b) Draw the front view, the top view and the left hand side view of a hexagonal right prism when its axis is parallel to the horizontal plane and parallel to the vertical plane. Two sides of the base are parallel to the horizontal plane. Use the THIRD ANGLE method of projection. [8]
Question 4.
Construct a diagonal scale.
Given : R.F. = 1 : 40, maximum length = 4 m.
Taking the measurements from this scale, construct a regular pentagon ABCDE of side = 2.37 m.
Draw a circle of radius = 1.42 m with the vertex A of the pentagon as its centre.
Draw two tangents to this circle from the vertex C of the pentagon. [16]
