Construction of Ordinary Scale
1. When drawings are drawn smaller than the actual size of the objects the scale used is said to be_________

A. Enlarging scale B. Reducing scale C. Small scale D. Decreasing scale

Answer: Option B
Explanation: Dimensions of large objects must be reduced to accommodate on standard drawing sheets. It is not any physical instrument but a ratio taken between actual and drawing object, the drawing is drawn small and this ratio is termed as reducing the scale. Don’t get confused as reducing-scale is also used by surveyors for reducing chains and links to acres and roods.
2. The ratio of length of the drawing of the object to the actual length of the object is called___________

A. Resulting fraction B. Representative figure C. Representative fraction D. Representative index

Answer: Option C
Explanation: Representative fractions are a unit-less relation between one “unit” on the map and however many “units” of the same type on the ground. When a 1 cm long line in a drawing sheet represents 1 m length of the actual object on the ground, the R.F is equal to 1 cm/1 m = 1/100. These are of 3 types-full scales, reduced scale, and enlarged scale.
3. The scale of chords is used to measure _________

A. Chords B. Lines C. Angles D. Diameter

Answer: Option C
Explanation: Used to read angle if there is no protractor. To draw an angle, compasses describe an arc from the origin with a radius taken from the 60 marks. The required angle is copied from the scale by the compasses and an arc of this radius drawn from the sixty marks so it intersects the first arc. The line drawn from this point to the origin will be at the target angle.
4. What is the use of circular vernier as a measuring instrument?

A. Measuring small angle B. Measuring large angle C. Measuring required accurate angle D. Normal angle

Answer: Option C
Explanation: Verniers are also extensively used to circular scales in variety of scientific instruments. The below figure shows typical arrangement of double direct verniers.
In Fig. the scale is graduated to 10 and value of n=10 on the vernier. 10 vernier divisions = 9 main scale divisions. Hence the least count is = [latex]\frac{d}{n}[/latex] = [latex]\frac{10}{10}[/latex] = 6 ́ . The reading is 19 0 48′.
5. If the measurement required is in three units, which scale would you prefer?

A. Plain B. Comparative C. Diagonal D. Vernier

Answer: Option C
Explanation: Diagonal scales are used when very minute distances such as 0.1 mm etc. are to be accurately measured or when measurements are required in three units; example- dm, cm and mm, or yard, foot and inch. While other options only give measurement in a single unit.

Drawing Plan and Elevation of Points, Lines, Surfaces & Solids.
1. Which among these is not the method of surface development?

A. Parallel-line development B. Radial-line development C. Triangulation development D. Geometric development

Answer: Option D
Explanation: There is nothing like Geometric development. The surface development methods are-
Parallel-line Method: It is used for developing prisms and single curved surfaces like cylinders, in which all the edges/generation of lateral surfaces are parallel in each other.
Radial-line Method: It is employed for pyramids and single curved surfaces like cones in which the apex is taken as a center and the slant edge or generator as the radius of its development.
Triangulation Method: It is used for developing transition pieces.
Approximate Method: It is employed for double-curved surfaces like spheres, as they are theoretically not possible to develop. The surface of the sphere is developed by the approximate method. When the surface is cut by a series of cutting planes, the cut surfaces is called a zone.

Drawing and detailing of Brick arrangements – Various types of Bonds
1. In ______ type of bond, all the brakes are arranged in the stretcher courses.

A. English bond B. Header bond C. Stretcher bond D. Flemish bond

Answer: Option C
Explanation: The stretcher bond is useful for one brick partition walls as there is no headers in such walls. As this bond does not develop a proper internal bond, it should not be used for walls having a thickness greater than that of the one-brick wall.
2. In _______ type of bond, all the bricks are arranged in header courses.

A. Header bond B. Flemish bond C. Dutch bond D. Facing bond

Answer: Option A
Explanation: Header bond does not have the strength to transmit pressure in the direction of the length of the wall. Hence it is not suitable for load-bearing walls. However this bond is used for curved surfaces in the brickwork because stretches if used for curved faces, would project beyond the face of the wall.
3. __________ bond is considered as the strongest Bond in brick work.

A. English bond B. Raking bond C. Garden-wall bond D. Dutch bond

Answer: Option A
Explanation: English bond is generally used in practice. In English bond, the alternate courses consist of stretchers and headers, the queen closer is put next to the queen header to develop the face slap and each alternate header is centrally supported over a stretcher.
4. In _______ type of bond, the headers are distributed evenly.

A. Stretcher bond B. Flemish bond C. Header bond D. English bond

Answer: Option B
Explanation: In Flemish bond, the headers are distributed evenly and hence, it creates a better appearance than the English bond. In Flemish Bond, in every course, the headers and stretchers are placed alternately. Here, the Quoin closer is put next to the Quoin header in alternate courses to develop the face lap.
5. In the ________ bond, one header course is provided after three or five stretcher courses.

A. English cross bond B. Facing bond C. Raking bond D. Garden-wall bond

Answer: Option D
Explanation: As the name suggests, the Garden-wall bond is used for the construction of the boundary walls, compound walls, Garden walls, etc. The wall is one brick wall and its height does not exceed 2 meters. The wall may be constructed either in English bond or Flemish bond.
