Engineering Drawing Practice Questions Set-2 for RRB ALP CBT-2 Exam

Engineering Drawing Questions

Engineering Drawing Practice Questions Set-2: In this post we are providing most important engineering drawing questions for RRB ALP CBT-2 Exam. An engineering drawing, a type of technical drawing, is used to fully and clearly define requirements for engineered items. Engineering drawing (the activity) produces engineering drawings (the documents). More than merely the drawing of pictures, it is also a language—a graphical language that communicates ideas and information from one mind to another. Engineering Drawing Practice Questions

Answers:

1. a
Explanation: Bureau of Indian Standards (B.I.S.), American Society of Mechanical Engineering (ASME), American Society for Testing and Materials (ASTM), U.S. National Institute of Standards and Technology (NIST).
2. c
Explanation: The untrimmed size of any sheet will be slightly larger than trimmed size. The untrimmed size for an A4 sheet is 240 mm x 330 mm where trimmed size is 210 mm x 297mm. The space between the trimmed sheet and the frame is called a border.
3. c
Explanation: SP: 46 (2003) recommends the borders of 20 mm width for the sheet sizes A0 and A1, and 10 mm for the sizes A2, A3, A4 and A5. The BIS-SP 46 is the standard used in the educational institution for engineering drawing.
4. b
Explanation: The sheet may be placed in any direction but within the sheet, the drawing should be specified particularly for reproduction purpose, the main purpose is to facilitate positioning of the drawing and parts in it.
5. d
Explanation: The size of the title block is 185mm x 65 mm which is recommended by B.I.S. (Bureau of Indian Standards), where 25mm x 10mm is for scale in drawing sheet. Within the title box, there will be so many sections divided like Name of the firm, Drawing No, Title, etc.




6. b
Explanation: The final size of the folded print in method 1 will be 297 x 190, while that in method 2 will be 297 x 210. In either case, the title block is visible at the top of the folded print. When prints are to be stored and preserved in cabinets they are folded by method 2.
7. c
Explanation: 0.5:1 is reducing scale which we can also be written as 1:2. In the remaining options, the antecedent is more than the consequent. So we can say if the antecedent is a decimal and consequent is the whole number then the ratio is said to be reducing scale.
8. b
Explanation: 1:10000 is reducing scale since antecedent is less than consequent. The ratio represents the object should be drawn 1/10000th of the original one. Usually, this much ratios will be used only when the machine parts are too big.
9. b
Explanation: French curves are used for drawing curves which cannot be drawn with a compass. Since we are just making a rough sketch of our drawing beforehand, for the actual drawing there is no need for French curves. The remaining are primary requirements to sketch any drawing.
10. b
Explanation: The correct statements are schematic assembly drawing: This type of assembly drawing is used for explaining the working principle of any machine. Exploded assembly drawing: It represents the details of a machine in a pictorial form as it is assembled. It helps the mechanics for dismantling machine for repairing purpose.




11. d
Explanation: Holding the pencil should be primary thing, getting a clear view on the drawing is next after we have to just draw with a light sketch so that we can understand how the sketch will be, and finishing with a dark sketch.
12. a
Explanation: For drawing, circle center should be the primary thing. Make the circle and through it draw horizontal and vertical center lines. Later we add four radial lines between them and then the paper maybe revolved for easy wrist motion to enable drawing.
