# Engineering Drawing Short Questions

Define engineering drawing. Why drawing is called universal language of engineers? Ans1:-A drawing drawn by an engineer having engineering knowledge for the drawing purposes is an engineering drawing. It is meant for communicating his ideas, thoughts and designs to others. Engineering drawing is a starting point of all engineering branches such as Mechanical, Production, Civil, Electrical, Electronics, Computer science, Chemical etc. It is spoken, read, and written in its own way.

Engineering drawing has its own grammar in the theory of projections, its idioms in conventional practices, its punctuations in the types of lines, its abbreviations, symbols and its descriptions in the constructions. Q2 – Name different types of drawing instruments. Ans2 – Drawing board, T-square, Set Square, Scales, Pencil and sand paper block, Drawing pins or cello-tape, Duster or handkerchief, eraser etc. Q3 – Why pencil is rotated in finger while drawing a long line? Ans3 – The pencil is rotated in finger while drawing a long line in order to get a line of uniform thickness throughout.

Q4 – How will you test the set square and T-square? Ans4 – Testing of T-square – (i) Check all screw heads and tighten, if necessary (ii) In order to check the T-square, first of all draw a horizontal line. Now reverse the T-square and again draw a horizontal line with working edge. If both the lines coincide with each other, then the working edge of Tsquare is alright. If there is a difference in two lines, then working edge is not correct and the line gives twice the error of the working edge. This error should be rectified by scraping the edge with a scraper or a sharp knife.

Testing of set-squares – The straightness of edges of the set-square can be checked by drawing a vertical line. Then reverse the set-square and draw again vertical line. If there is any difference between the two vertical lines then working edge is not correct and the line gives twice the error. This error can be removed by straightening the edges by means of a scraper or sand paper. Q5 – What are the standard sizes of drawing sheets according to I. S. I. and which is suitable for drawing work? Ans5 – The standard size of sheets according to I. S. I. are A0(1189 X 841), A1 841 X 594), A2(594 X 420), A3(420 X 297), A4(297 X 210) and A5(210 X 148). Drawing sheet of size 594 X 420 i. e. A2 size is generally used by engineering students as it is very handy and easy for drawing work in class. Q6 – What are the ways of sharpening a pencil for good and accurate work and which type of pencil is more suitable for drawing work? Ans6 – There are two ways of sharpening a pencil (i) a small piece of sand paper of zero grade, pasted upon a piece of wood. (ii) Sharpeners. Usually hard pencils such as H, 2H etc are used for making the engineering drawing.

Q7 – Why cello-tape is used instead of drawing pins, now a day? Ans7 – Now a days, cello tapes are used in place of drawing pins for its practical convenience as the drafter, Tsquare and set-squares can be moved easily over the tape. Q8 – What is layout of drawing sheet? Ans8 – The selection of suitable scale and allotment of proper space for margin, title block, parts list, revision panel, folding marks etc. on the drawing sheet is known as layout of drawing sheet. Q9 – Why is the layout of sheet is necessary? Ans9 – Layout of the drawing on the drawing sheet is necessary in order to make its reading easy and speedy.

The title blocks, parts list etc will provide all the required information.

Q12 – What do you mean by convention or code? Ans12 – The representation of any matter by some sign or mark on the drawing is known as convention or code. The conventions make the drawing simple and easy to draw. Q13 – What do you understand by thickness of lines? Ans13 – There are three distinct thickness of lines used in engineering drawing. These lines are specified as thick, medium and thin lines. The line specified as thick is usually 3 times thicker and the line specified as medium is 2 times thicker than a thin line. Q14 – Where and why a cutting plane is drawn in a drawing?

Ans14 – The section plane are generally perpendicular planes. The projection of a section plane, to which it is perpendicular, is a straight line. This line will be parallel, perpendicular or inclined to the x-y line. The cutting plane is drawn in a drawing to show the inner details of an object. Q15 – What is the necessity of convention breaks and convention of materials? Ans15 – Long members of uniform cross-section such as rods, shafts, pipes etc. are generally shown in the middle by the conventional breaks so as to accommodate their view of whole length on the drawing sheet without reducing the scale.

The exact length of the member is shown by the dimension. Q16 – Why the conventional representation of common features are adopted on the drawing? Ans16 – The conventional representation of common features are adopted on the drawing to save the unnecessary time or space on the drawing. Q17 – What are the main requirements of lettering?
