• True

• False

Which of the following tools is used to draw horizontal lines?

• Mini–drafter

• Protactor

• T –square

• French

Which of the following does NOT correctly describethe main standards and codes used in engineering drawings?

• ISO (International Organization for Standardization)

• ANSI (American NationalStandards Institute)

• JIS (Jawa Industrial Standards)

• DIN (Deutsches Institut für Normung)

The areas of the two subsequent sizes of drawing sheet are in the ratio

• 1:5

• 1:4

• 1:2

• 1:10

Why do we need engineering drawing standards?

• To eliminate the originality/creativity of the drafter.

• To modify and organize a way of drafting.

• To have effective communication of drawings.

• To eliminate mistakes.

By referring to Figure 1, given are the steps to draw a perpendicular to a line at a point within the line whenthe point is near the centre of a line. Arrange the steps.Let AB be the line and P be the point in it.

i. P as centre, take convenient radius R1 and draw arcson the two sides of P on the line at C and D

ii. Join E and P

iii. The line EP is perpendicular to AB

iv. Then from C and D as a centre, take R2 radius (greaterthan R1), draw arcs which cut at E

• i, iv, ii, iii

• iii, ii, iv, i

• iv, iii, i, ii

• ii, i, iv, iii

By referring the Figure 2, given are the steps on howto construct an acute angle of 60o?

i. Place the point of the compass at A and draw an arc that passes through O

ii. Join 0 to B. The angle ∠AOB is 60o

iii. Draw the line Ol

iv. Place the point of the compass at O and draw an arc that passes through AB

• i, iii, ii and iv

• iii, i, iv and ii

• iii, iv, i and ii

• i, ii, iii and iv

• A.     Dashed lines

• A.     Thin straight lines

• A.     Very light thick lines

1.      How does orthographic sketching start after analyzing the object?

•    By drawing the proportionate outlines of the object

•    By blocking the front, top, and side views of the object

•    By drawing the required curves of the object

• By detailing the object
