This set of Engineering Drawing Multiple Choice Questions & Answers (MCQs) focuses on “Manual Drawing and Drawing Standards – 1”.
1. What is the full form of BIS?
a) The business of International Standard
b) Bureau of International Standard
c) Bureau of Indian Standard
d) The business of Indian Standard
Explanation: In order to practice and understand the drawing effectively, the engineering drawing with manual drafting tools with the incorporation of the dimensioning and lettering formalities as recommended in Bureau of Indian Standards (BIS).
2. The general representation of surface treatment indication locations are?
d) − − − −
Explanation: There are 15 basic types of lines used in engineering drawing practice which are identified by their designating number as per BIS specification. So for surface treatment indication locations, long dashed dotted wide lines (chain wide lines) are used.
3. A mini drafter helps in __________
a) Drawing parallel and perpendicular lines
b) Drawing smooth curves
c) Drawing circles
d) Measuring the length of a curve
Explanation: The mini drafter is a device which combines the functions of a T-square, protractor, set square and scale. We can’t draw curves or circles with the help of mini drafter.
4. The leader lines are used to indicate _________
a) Dimensions of the feature
b) Pinpoint a location
c) Indicate a surface
d) To mark the center of small circles
Explanation: They are drawn usually at an angle to the representation and touch the feature with an indication of an arrow.
5. The system of dimensioning is generally adopted in large-sized drawing such as buildings, air-crafts and automobiles are off _________ method.
a) Aligned method
b) Unidirectional method
c) Chain dimensioning method
d) Combined dimensioning method
Explanation: In this method, the dimensions are indicated so that they can be placed in an only horizontal direction. Non-horizontal dimension lines are interrupted, and the dimension values are inserted perpendicularly to such lines.
6. What is another name for parallel dimensioning?
a) Combined dimensioning
b) Progressive dimensioning
c) Dimensioning of repeated features
d) Chain dimensioning
Explanation: All the single dimension lines of different features are placed parallel to one another and successively one below the other or one adjacent to the other, from a common extension line as a reference. This helps to refer all the dimensions from a common datum in a progressive manner.
7. The dimension line represents_________
a) Pinpoint a location
b) To mark the center of small circles
c) Indicate a surface
d) Dimensions of feature
Explanation: It is generally a continuous line drawn parallel to the other edge. The numerical value of the dimension is written above this line.
8. The identification symbol of the spherical radius is _________
Explanation: The identification symbol of the radius is R and hence spherical radius is indicated by SR. Where SP represents Equi-spaced, Sᴓ represents spherical diameter and Sq represents a square.
9. What strokes can be used where the space is too small to draw an arrowhead?
a) Dimensional strokes
b) Unidirectional strokes
c) Oblique strokes
d) Leader strokes
Explanation: The dimension lines will have terminations in the form of arrowheads or oblique strokes. So the oblique strokes can be used where the space is too small to draw an arrowhead.
10. The width “d” of all types of lines is decided by the mathematical series which bears the common ratio is _________
Explanation: The width of the line, here, means the thickness of the line, and it remains constant throughout the whole line. Based on width any line can be classified such as narrow (thin), wide (medium), extra wide (thick).
