Unit of dimensions for ballast is __________(a) cm(b) micro m(c) mm(d) cu m |
|
Answer» Correct option is (c) mm Easy explanation: Track ballast forms the track bed upon which railroad ties (sleepers) are laid. It is packed between, below, and around the ties. It is used to bear the load from the railroad ties, to facilitate drainage of water, and also to keep down vegetation that might interfere with the track structure. This also serves to hold the track in place as the trains roll by. It is typically made of crushed stone, although ballast has sometimes consisted of other, less suitable materials, for example burnt clay. The term “ballast” comes from a nautical term for the stones used to stabilize a ship. |

Unit of measurement of supply of bare electric wire in FPS is _________(a) per quintal(b) per cu cm(c) per cwt(d) per m |
|
Answer» Right option is (c) per cwt To explain I would say: The hundredweight (abbreviation: cwt), formerly also known as the centum weight or quintal, is an English, imperial, and US customary unit of weight or mass of various values. Its present value continues to differ between the American and imperial systems. The two values are distinguished in American English as the “short” and “long” hundredweight and British English as the “cental” and the “hundredweight”. • The short hundredweight or cental of 100 lb (45.359237 kg) is used in the US and Canada. • The long or imperial hundredweight of 8 stone (112 lb or 50.802345 kg) sees informal use in the imperial system but according to Schedule 1, Part VI of the Weights and Measures Act 1998, is no longer to be used for trade after the Act came into force. |

Which is not the nominal thickness of D.P.C?(a) 2cm(b) 2.5cm(c) 4cm(d) 2.5″ |
|
Answer» Right choice is (d) 2.5″ Best explanation: Damp proofing is accomplished several ways including: • A damp-proof course (DPC) is a barrier through the structure designed to prevent moisture rising by capillary action such as through a phenomenon known as rising damp. Rising damp is the effect of water rising from the ground into property. The damp proof course may be horizontal or vertical. A DPC layer is usually laid below all masonry walls, regardless if the wall is a load bearing wall or a partition wall. • Integral damp proofing in concrete involves adding materials to the concrete mix to make the concrete itself impermeable. • Surface coating with thin water proof materials for resistance to non-pressurized moisture such as rain water or a coating of cement sprayed on such as shotcrete which can resist water under pressure. • Cavity wall construction, such as rainscreen construction, is where the interior walls are separated from the exterior walls by a cavity. • Pressure grouting cracks and joints in masonry material. |

The superstructure of a building is the part that is entirely above its foundation or basement.(a) True(b) FalseThis question was addressed to me in unit test.My doubt is from Circular, Semicircular, Hexagonal & Half Hexagonal Rooms in chapter Methods of Building Estimate & Estimate of Building of Civil Engineering Drawing |
|
Answer» The correct option is (a) True Easy explanation: A superstructure is an upward extension of an existing structure above a baseline called Ground Level in general and it usually serves the purpose of the structure’s intended use. In Buildings, the portion of the structure that is above ground level that receives the live load is referred to as Superstructure. The superstructure of a building is the part that is entirely above its foundation or basement. |

Figure shown below represents __________(a) fan truss(b) scissor truss(c) triangular truss(d) inclined truss |
|
Answer» Right choice is (b) scissor truss Easy explanation: The scissor truss gets its name from being shaped like a pair of shears (scissors). Two defining features of a scissor truss are: 1) the joint where the bottom chords pass (the hinge of a pair of scissors) must be firmly connected and 2) the rafter (top chord) feet must land on the bottom chords. If the bottom chords join to the under-side of the top chords the assembly is said to be “scissor braced” rather than a scissor truss. |

With a very small structure a single column with an umbrella structure above may be acceptable.(a) True(b) FalseThe question was asked during an interview.This is a very interesting question from Circular, Semicircular, Hexagonal & Half Hexagonal Rooms topic in section Methods of Building Estimate & Estimate of Building of Civil Engineering Drawing |
|
Answer» The correct choice is (a) True Explanation: For a larger structure columns may be placed on the radius at 2/3 of the roof’s radius. This results in minimal roof stresses. But while a circular structure with main structural elements being radial and passing through the center sounds good, it is unbuildable with more than 8 columns due to connections at the center. Past this point we need to develop some sort of structural placement drawing for the final roof and use that to locate the columns. |

__________ will be the edges of inclined or oblique planes of an object as represented in a multi-view drawing.(a) Inclined lines(b) Non-isometric lines(c) Isometric lines(d) Curved lines |
|
Answer» Correct choice is (b) Non-isometric lines Best explanation: Non-isometric lines will be the edges of inclined or oblique planes of an object as represented in a multi-view drawing. It is not possible to measure the length or angle from an inclined or oblique line in a multi-view drawing and then transferring these distances to draw the line in an isometric drawing. Instead, non-isometric lines must be drawn by locating the two end points of the lines on isometric lines and then connecting these end points with a line. The process used is called offset measurement, which is a method of locating one point by projecting another point. |
|
| 38. |
The shape of isometric drawing will be ______________(a) a plus(b) a cuboid(c) a staircase(d) a triangular prism |

Here which type of isometric drawing view does the figure represents?(a) 3-Dimensional(b) Top, Front and Side(c) Multi-view drawing(d) Orthographic |
|
Answer» The correct choice is (c) Multi-view drawing Explanation: Multi-view drawings employ multi-view projection techniques. In multi-view drawings, generally three views of an object are drawn, and the features and dimensions in each view accurately represent those of the object. Each view is a 2-D flat image. The views are defined according to the positions of the planes of projection with respect to the object. |

The measurement is made for stone work in square metre in case of __________(a) wall facing(b) columns, lintels, copings(c) fotings(d) building work |
|
Answer» The correct option is (a) wall facing The best explanation: Stone blocks used in masonry can be dressed or rough, though in both examples: corners, door and window jambs, and similar areas are usually dressed. Stone masonry utilizing dressed stones is known as ashlar masonry, whereas masonry using irregularly shaped stones is known as rubble masonry. Both rubble and ashlar masonry can be laid in coursed rows of even height through the careful selection or cutting of stones, but a great deal of stone masonry is uncoursed. |

What curve does the locus represent if the locus of a moving point which is always equidistant from the points (2, -1) and (3, 2)?(a) Hyperbola(b) Straight line(c) Ellipse(d) Circle |
|
Answer» The correct choice is (b) Straight line To elaborate: Let A (2, -1) and B (3, 2) be the given points and (x, y) be the co-ordinates of a point P on the required locus. Then, PA^2 = (x – 2)^2 + (y + 1)^2 and PB^2 = (x – 3)^2 + (y – 2)^2 By problem, PA = PB or, PA^2 = PB^2 or, (x – 2)^2 + (y + 1)^2 = (x – 3)^2 + (y – 2)^2 or, x^2 – 4x + 4 + y^2 + 2y + 1 = x^2 – 6x + 9 + y^2 – 4y + 4 or, 2x + 6y = 8 or, x + 3y = 4 ……… (1) Clearly, equation (1) is a first degree equation in x and y; hence, the locus of P is a straight line whose equation is x + 3y = 4. |
