Answer: a [Reason:] 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).

Answer: c [Reason:] 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 border.

Answer: c [Reason:] 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.

Answer: b [Reason:] 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.

Answer: d [Reason:] 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.

Answer: b [Reason:] 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.

Answer: c [Reason:] 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 antecedent is a decimal and consequent is whole number then the ratio is said to be reducing scale.

Answer: b [Reason:] 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.

Answer: b [Reason:] 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.

Answer: b [Reason:] The correct statements are schematic assembly drawing: This type of assembly drawing is used for explaining 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.

Answer: d [Reason:] Holding the pencil should be primary thing, getting clear view on 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.

Answer: a [Reason:] 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.

Answer: a [Reason:] The dimension line is a thin continuous line with the ends terminating in arrowheads and is enclosed by extension lines, outlines or centre lines. The dimension figures is written on the top of the dimension line or aligned at the centre of the dimension line according to the system of dimensioning.

Answer: d [Reason:] Extension line is a thin continuous line which encloses the dimension line and they are generally drawn 1mm away from the outlines. They need to drawn near to the outlines and far away from the outlines.

Answer: c [Reason:] Usually in engineering drawing, the arrowheads used are closed and neatly filled. They are made by hand in proportion to the thickness of the outline. The length of the arrowhead is three times the width of the arrowhead.

Answer: b [Reason:] A note is used to indicate information about the operation done on a particular feature. It is written near to the feature and usually it is shown outside the view. With this type of information of the drawing manufacturing of the part becomes easy.

Answer: c [Reason:] A leader is thin continuous line with one end terminating in arrowhead and the other with a period. While dimensioning arcs or circles, leaders are aligned to the radius of the respective arcs or circles.

Answer: d [Reason:] The leaders are drawn at an inclination of more than 30˚. They should not be placed vertical, horizontal and less than 30˚ to the respective feature. The arrowhead should touch the feature they are describing or dimensioning.

Answer: b [Reason:] A leader line can never be drawn curved. They should be drawn straight and inclined at an angle not less than 30˚. They should not be placed vertical or horizontal in the views. One side of the leader line should terminate in arrowhead and the other in period.

Answer: c [Reason:] In the given example, the diameter of the circle is not dimensioned. Diameter of a circle is a very prominent feature and should not be missed while dimensioning. The dimensions are so given that they do not require any further calculations. The above example is the incorrect way of dimensioning.

Answer: b [Reason:] While dimensioning a feature with a square cross-section, ‘SQ’ should be added before the dimension figure to indicate its shape. For dimensioning the base circle of a cylinder, the symbol ‘φ’ is added before the dimension figure.

Answer: c [Reason:] Since in all views, a sphere is seen as circle. While dimensioning a sphere it is important to add ‘SPHERE’ in front of the dimension figure giving information about the diameter of the sphere. Fore example, a sphere with 25mm diameter will be dimensioned as ‘SPHERE 25’.

Answer: b [Reason:] A note is used to indicate the operations done on a feature if there any. The note accompanied by a leader line which terminates in arrowhead on one side and a period on other side. For example, the threads on feature may have a note indicating whether it is a single start or double start.

Answer: a [Reason:] Tapers and slopes are part of dimensioning. They are calculated through their respective formulas and are indicated as 1: x, near the feature which has the slope or taper on them. While drawing these features, having this information sure comes handy.

Answer: d [Reason:] The stages are i) keeping in simple position, ii) Axis inclined to one plane and parallel to the other, iii) Final position. The 2nd and 3rd positions may be obtained either by the alteration of the positions of the solid i.e. view or reference lines.

Answer: a [Reason:] As the 1^st stage is to keep the solid in simple position and given is front view it is rectangle and then rotated to an angle of 45 degrees with H.P which again gives rectangle and then rotating 30 degrees with V.P which gives an irregular hexagon.

Answer: b [Reason:] As the 1^st stage is to keep the solid in simple position and given is top view it is square and then rotated to an angle of 45 degrees with H.P which gives rectangle and then rotating 30 degrees with V.P which gives again rectangle.

Answer: b [Reason:] As the 1^st stage is to keep the solid in simple position and given is top view it is circle and then rotated to an angle of 30 degrees with H.P which gives triangle with base as ellipse and then rotating 45 degrees with V.P which gives again triangle with base as ellipse.

Answer: c [Reason:] As the 1^st stage is to keep the solid in simple position and given is front view it is triangle and then rotated to an angle of 30 degrees with H.P which again gives triangle and then rotating 45 degrees with V.P which gives triangle with base as ellipse.

Answer: a [Reason:] As the 1^st stage is to keep the solid in simple position for given conditions the solid’s base should be placed on V.P so front view gives pentagon and then rotated so as to one of the face touch the V.P now the view will become irregular pentagon and then adjust so that edge of base on V.P makes 30 degrees with H.P so it show irregular pentagon from front view.

Answer: c [Reason:] As the 1^st stage is to keep the solid in simple position for given conditions the solid’s base should be placed on V.P so top view gives triangle and then rotated so as to one of the face touch the V.P now the view will remain triangle and then adjust so that edge of base on V.P makes 30 degrees with H.P so it show irregular pentagon from top.

Answer: a [Reason:] As in the 1^st stage the cube is to placed in the position occurred when the diagonal of base perpendicular to V.P so front view gives rectangle and then rotated so as to keep one of the corners only on H.P so the front view will be rectangle then if we make diagonal perpendicular to V.P the front view will be regular hexagon.

Answer: b [Reason:] As in the 1^st stage the cube is to be placed in the position occurred when the diagonal of base perpendicular to V.P so top view gives square and then rotated so as to keep one of the corners only on H.P so the top view will be irregular hexagon then if we make diagonal perpendicular to V.P the top view will be irregular hexagon.

Answer: b [Reason:] As in the 1^st stage the pentagonal prism is to be placed in simple position the axis perpendicular to V.P so top view gives pentagon and then rotated so as to keep one of the corners only on H.P so the top view will be irregular heptagon then adjusting the axis so as to make 30 degrees with xy reference line so top view remain same.

Answer: a [Reason:] As in the 1^st stage the pentagonal prism is to be placed in simple position the axis perpendicular to V.P so front view gives rectangle and then rotated so as to keep one of the corners only on H.P so the front view will remain same then from projections of top view the front is drawn so a irregular heptagon will form.

Answer: b [Reason:] In the 1^st stage the solid’s axis is perpendicular to H.P and one base’s edge is perpendicular to V.P. so the top view will be pentagon and then made to rest on only one edge so top view will be irregular polygon of 4 sides and then adjusted to a given angle so top view will be same.

Answer: a [Reason:] In the 1^st stage the solid’s axis is perpendicular to H.P and one base’s edge is perpendicular to V.P. so the front view will be triangle and then made to rest on only one edge so front view will remain same and then adjusted to a given angle so front view will be pentagon.

Answer: d [Reason:] A regular polygon is a shape with 4 or more sides and all the sides are of equal length. A regular polygon with five, six, seven, etc. sides are called as regular pentagon, regular hexagon, regular heptagon, etc. respectively.

Answer: a [Reason:] For drawing a regular hexagon, the fastest method is to draw a circle with diameter equal to the length of the side of the regular hexagon and then dividing the circle into six parts by cutting arcs equal to the diameter of the circle on its circumference. Then the intersection points are joined to form the hexagon.

Answer: c [Reason:] An ogee curve is a curve with two curves in which one curve is a reverse of the other curve. Both curves are of same radii. They both are tangent to parallel lines or in other words the tangents to both the curves are parallel to each other.

Answer: c [Reason:] For drawing a polygon with side of given length, first we draw a semicircle with centre at one of the ends of the length and the radius as the length. The next step is to divide the semicircle into the number of sides of the polygon.

Answer: d [Reason:] The second step in drawing a polygon is to divide the semicircle into the number of sides the polygon has. In the first we draw a semicircle with centre at one of the ends of the length and the radius is taken as the length of the side of the polygon.

Answer: a [Reason:] The third step involved in drawing a polygon is to join the points one being the second division on the semicircle and the other being the first centre through which the c=semicircle was made in the first step.

Answer: b [Reason:] In drawing a regular hexagon using a T-square and a 30˚-60˚ set square, we draw parallel lines and not circles. As it is impossible to draw circles using T-square and 30˚-60˚ set squares. We draw these parallel lines using angles.

Answer: a [Reason:] To draw an arc of given radius touching two straight lines at right angles with each other, we first draw an arc with centre at the intersection point of the two lines on both the lines. Then we draw another from the new intersection of the arc and the lines.

Answer: a [Reason:] In the second step in drawing the arc of given radius touching two straight lines at right angles with each other, we draw another arc from the centre at the new intersection of the arc and the lines and keeping the radius same. The intersection of these two new arcs is the centre of the required arc.

Answer: b [Reason:] The tangent to both the curves in an ogee curve is parallel and not perpendicular to each other. An ogee curve is a curve with two curves with one of the curve being a reverse curve to the other. Hence it is also called as reverse curve.
