technical Drawing

The diagram illustrates the proper method of

• constructing an ellipse with trammel

• constructing hyperbola as a conic section

• finding the foci, the normal and the tangent of an ellipse

• finding the focus of a parabola and the tangent at a point

In the construction show the angle X is

• 60'

• 65'

• 70'

• 75'

The fire emergency exit doors leading form a workshop should be open

• upwards

• outwards

• sideways

• inwards

In the drawing,EF to EF1 is in the ratio 3:4. The lenght of EF1 is

• 90

• 60

• 30

• 15

The conic section at A-A appears as

• a circle

• a triangle

• an ellipse

• a parabola

When a straight line touches and arc and forms a right angle with the radius of the circle.

• a chord is formed

• a point of tangency is formed

• the curve blends exactly

• the line and the arc are similar in shape

In the diagram, ABCD is parallelogram. the triangle CDEis equal in are to

• ABCD

• 1/4 ABCD

• 1/3 ABCD

• 1/2 ABCD

The diagram show a square equal in area to rectangle.

What is the lenght of EF in the construction?

• 15mm

• 35mm

• 55mm

• 75mm

• square

• rhombus

• rectangle

• trapezium

Which of the following is used to draw an octagon if the lenght of one side is given?

• A 60' set square

• A 45' set square

• A protractor, using the 40'angle

• A Protractor, using the 72' angle
