51.	What is the general application of the line shown below?(a) Hidden edges(b) Extension(c) Cutting planes(d) ProjectionThis question was posed to me during an interview for a job.I want to ask this question from Lines, Lettering and Dimensioning in section Lettering Practice, Scales & Curves of Civil Engineering Drawing
Answer» The correct choice is (C) Cutting planes Easiest explanation: Cutting PLANE lines represents a plane or planes in which a sectional view is taken. The arrow INDICATES the DIRECTION of cutting the section. Here the upper or front PORTION of the section will be visible (in the diagram above).

52.	Which line is drawn to make the section evident?(a) Long-break line(b) Chain thick(c) Border line(d) Hatching lineThe question was posed to me in an interview for job.I need to ask this question from Lines, Lettering and Dimensioning topic in division Lettering Practice, Scales & Curves of Civil Engineering Drawing
Answer» The correct option is (d) Hatching line For explanation: These LINES are drawn to MAKE the section BOLD or visible. These are continuous THIN lines and are generally drawn at an angle of 45 degree to the MAIN outline of the section.This figureshows hatching line (inclined lines), it can be any line.

53.	What is the scale ratio of full size scales?(a) 1:2(b) 1:3(c) 1:10(d) 1:1I got this question by my college professor while I was bunking the class.Origin of the question is Scales topic in division Lettering Practice, Scales & Curves of Civil Engineering Drawing
Answer» Correct option is (d) 1:1 For EXPLANATION: As the name SUGGESTS it does not make any changes in the SCALE, no increment or decrement to the figure is done. The dimensions for drawing will be full, same in PROPORTION and size as the actual object dimensions.

54.	The scale of chords is used to measure _________(a) Chords(b) Lines(c) Angles(d) DiameterI had been asked this question during a job interview.My doubt stems from Scales in division Lettering Practice, Scales & Curves of Civil Engineering Drawing
Answer» Correct choice is (C) Angles To explain I WOULD say: Used to read ANGLE if there is no protractor. To draw an angle, compasses describe an arc from ORIGIN with a radius taken from the 60 mark. The required angle is copied from the scale by the compasses, and an arc of this radius drawn from the sixty mark so it intersects the first arc. The line drawn from this POINT to the origin will be at the target angle.

55.	In n the following figure line C is used for irregular boundaries, what is its name?(a) Construction line(b) Long-break lines(c) Short-break line(d) Irregular lineI have been asked this question in a national level competition.The origin of the question is Lines, Lettering and Dimensioning in division Lettering Practice, Scales & Curves of Civil Engineering Drawing
Answer» Correct answer is (c) Short-break line To explain: Short- break LINES usually shortens an object that otherwise WOULD be longer at a real WORLD scale. These are CONTINUOUS, thin, heavy, semi-parallel, wavy lines. They are drawn free hand for consistent shaped objects and are used to SHOW short break or irregular boundaries.

56.	Chords which are ___________ from the centre are equal.(a) unequal(b) equidistant(c) one third(d) two thirdI had been asked this question in an internship interview.Origin of the question is Loci of Points topic in portion Lettering Practice, Scales & Curves of Civil Engineering Drawing
Answer» Correct OPTION is (b) equidistant Explanation: In the figure below, for ∆’s AOM and CON OM = ON(to prove) OA = OC(radii of the same circle) AM = CN OR 2AM = 2 CN(since OM ON are perpendicular to the chords and it bisects the chord and AM = MB, CN = ND) Angle AMO and CNO = 90° ∆AOM SIMILAR to ∆CON(R.H.S rule) OM = ON (CPCT)(required).

57.	The curve generated by a point fixed to a circle outside its circumference as it rolls along a straight line is called a _________(a) Inferior epitrochoid(b) Superior trochoid(c) Inferior trochoid(d) Superior epitrochoidThe question was asked in an online quiz.The origin of the question is Curves Used in Engineering Practice in section Lettering Practice, Scales & Curves of Civil Engineering Drawing
Answer» The CORRECT option is (b) Superior trochoid Best explanation: Trochoid is a curve generated by a POINT fixed to a CIRCLE, within or outside its circumference, as the circle rolls ALONG a straight line and if the points would had have been outside the circumference of the circle then it would have been called as superior trochoid. The below diagram shows a superior trochoid.

58.	For a plain scale, RF = \(\frac{1}{4}\) and M.L = 5decimeters, what is LOS?(a) 1.25 cm(b) 12.5 cm(c) 12.5 m(d) 12.5dmI got this question in my homework.My doubt is from Scales in section Lettering Practice, Scales & Curves of Civil Engineering Drawing
Answer» Right OPTION is (B) 12.5 cm The best I can explain: LOS = R.FM.L = \(\frac{1}{4}\)5 *10 cm (Since 1dm = 10 cm) = 12.5 cm.

59.	Which statement is correct for the locus shown in the figure below?(a) A point P moving in a plane about another point in such a way that its distance is constant(b) A point P moving in a plane about a fixed line as an arc with same centre(c) A point P moving in a plane about another point in such a way that its distance from a fixed line AB is constant(d) A point equidistant from two fixed non-parallel lines AB and CD in the same planeI had been asked this question in an international level competition.I need to ask this question from Loci of Points topic in chapter Lettering Practice, Scales & Curves of Civil Engineering Drawing
Answer» Correct choice is (b) A point P moving in a plane about a fixed line as an ARC with same centre The explanation: As per arc postulate regarding locus it is stated as: When the fixed line is an arc of a circle, the locus will be another arc drawn through same centre. Here fixed line is an arc AB and the locus drawn is an arc representing the circumference, PRODUCED DUE to point P.
