Right answer is (a) Function

To explain: In mathematics, a function is a relation between a set of inputs and a set of PERMISSIBLE outputs with the PROPERTY that each input is related to EXACTLY one output. An example is the function that relates each real number x to its square x2. The output of a function f corresponding to an input x is denoted by f(x) (read “f of x”). In this example, if the input is −3, then the output is 9, and we MAY write f(−3) = 9. Likewise, if the input is 3, then the output is also 9, and we may write f(3) = 9. (The same output may be produced by more than one input, but each input gives only one output.) The input variable(s) are sometimes referred to as the ARGUMENT(s) of the function.

Correct choice is (b) Vertical straights

Explanation: To offset an OBJECT, select the source object; click the offset button from the Edit Object Toolbar. Specify a point on canvas to offset through using TAP or drag.

The Offset command creates a new object whose shape is PARALLEL to that of the selected object. The Offset button is located in the Edit Object toolbar when tapping on any editable shape.

After the offset distance was SPECIFIED, you can SET it manually by inserting a value to the units bar (by tapping on the input box). Tap “Done” (“V” button) to finish specify the distance.

Correct choice is (b) per no.

For explanation I would say: A door is a solid barrier i.e. fixed in the opening of a wall. It can be OPENED for access to and from buildings and between the rooms or closed for privacy. The door has two parts: one part is frame and second part is shutters.

A window is an opening in a wall, door, roof or vehicle that allows the passage of light, sound, and air. Modern WINDOWS are usually glazed or COVERED in some other transparent or translucent material, a sash set in a frame in the opening; the sash and frame are also referred to as a window. Many glazed windows may be opened, to allow ventilation, or closed, to exclude inclement weather. Windows often have a latch or similar mechanism to lock the window shut or to HOLD it open by various AMOUNTS.

Correct choice is (a) Z-axis

Easy EXPLANATION: The User Coordinate System defines

• The XY plane, also called the work plane, on which objects are created and modified

• The horizontal and vertical directions used for features like Ortho mode, polar tracking, and object snap tracking

• The alignment and angle of the grid, hatch patterns, TEXT, and DIMENSION objects

• The origin and ORIENTATION for coordinate entry and absolute reference angles

• For 3D operations, the orientation of work planes, projection planes, and the Z axis for vertical direction and axis of rotation

You can change the location and orientation of the current UCS by clicking the UCS icon and using its grips, or with the UCS command.

 Display options for the UCS icon are available with the UCSICON command.

Right CHOICE is (C) Y- type nomograph

The EXPLANATION: Y- type nomograph does not exist. The other fourth type of NOMOGRAPHS includes PARALLEL scales nomograph.

Right OPTION is (c) 10^-18

To explain: Multiplying FACTOR for PREFIX “ATTO” is 10^-18.

Correct option is (c) Join

To elaborate: Some reasons you MAY choose to use polylines include the following:

• Vertices remain joined even after grip editing

• Absolute line width (as an ALTERNATIVE to relative line weight) that can be constant or TAPERED across a segment

• MOVE and copy a polyline as a unit

• Easily create rectangles and polygons as single objects

• SMART application of non-continuous line types across vertices

• Easy extrusion for 3D solids in AutoCAD.

The correct choice is (b) per cu m

Easy explanation: Lumber (American English; used only in North AMERICA) or timber (used in the rest of the English speaking world) is a type of wood that has been processed into beams and planks, a stage in the PROCESS of wood production.

Lumber may be supplied either roug-sawn, or surfaced on one or more of its faces. Besides pulpwood, rough lumber is the raw material for furniture-making and other items requiring additional cutting and shaping. It is available in many species, usually hardwoods; but it is also readily available in softwoods, such as white PINE and red pine, because of their LOW cost. Finished lumber is supplied in standard sizes, mostly for the construction industry – primarily softwood, from coniferous species, including pine, FIR and spruce (collectively spruce-pine-fir), cedar, and hemlock, but also some hardwood, for high-grade flooring.

The correct choice is (c) 08% and 08%

For explanation I would say: Pipes must be installed to MEET requirements for durability, SAFETY and thermal performance-

• CONTRACTOR responsibilities

• general installation requirements

• where to lay pipework

• ACCESS for maintenance and replacement

• preventing electric shock

• PIPE insulation.

The correct CHOICE is (b) GRID

Explanation: Grid is used to inhance the drawing SPEED and efficiency with specified spacing, angle and ALIGNMENT. Snap RESTRICTS the movement of the crosshairs to intervals that you define.

The correct choice is (a) sq m

The best EXPLANATION: A partition wall is a wall that separates rooms, or DIVIDES a room. Partition walls are usually not load-bearing. Partition walls are constructed of many materials, including steel panels, bricks, blocks of clay, terra-cotta, concrete, or glass blocks.

Some partition walls are MADE of sheet glass. Glass partition walls are a series of individual toughened glass panels mounted in wood or metal FRAMING. They may be suspended from or slide along a robust aluminium ceiling track. The system does not require the use of a floor GUIDE, which allows easy operation and an uninterrupted threshold.

The correct choice is (C) Scale MODULUS

Easiest explanation: Scale modulus M = Constant coefficient of function * Functional modulus

Z = 2x + 2Y = 2 (x+y)

M = 2* m.

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.

The CORRECT answer is (b) 3%-5%

Easy explanation: The dictionary meaning of CONTINGENCIES is defined as- A future event or circumstance

which is possible but cannot be PREDICTED with certainty or a provision for a possible event or

circumstance. In engineering is said to be as an incidental EXPENSE.

Right choice is (b) 1

The EXPLANATION: The following are the most commonly used layer settings in the Layer Properties Manager. You click the icon to turn the setting on and off.

• Turn off layers. You turn off layers to REDUCE the visual complexity of your drawing while you work.

• Freeze layers. You freeze layers that you do not need to access for a while. Freezing layers is similar to turning them off, but improves performance in very large drawings.

• Lock layers. You lock layers when you want to prevent accidental changes to the objects on those layers. Also, the objects on locked layers appear FADED, which helps reduce the visual complexity of your drawing, but still lets you see the objects faintly.

• Set default properties. You set the default properties for each layer, including color, linetype, LINE weight, and transparency. New objects that you create will use these properties UNLESS you override them. Overriding layer properties is explained later in this topic.

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.

Right answer is (c) Bed PLATE upto 4″depth

Easy explanation: The Bedplate is the foundation on which the 2 stroke engine is built. It must be rigid enough to SUPPORT the weight of the rest of the engine, and maintain the crankshaft, which sits in the bearing HOUSINGS in the transverse girders, in alignment.

The CORRECT ANSWER is (a) per kg

Easy explanation: Yarn is a long continuous length of interlocked fibres, suitable for use in the production of textiles, sewing, crocheting, knitting, weaving, embroidery, and ropemaking. Thread is a TYPE of yarn intended for sewing by hand or machine. Modern manufactured sewing threads may be finished with wax or other lubricants to withstand the stresses involved in sewing. Embroidery threads are yarns specifically DESIGNED for hand or machine embroidery.

Right option is (d) 3 times 1 surface area, both sides

The explanation: In Italy it is one of the most common and appreciated decorative plaster. We are talking about the Venetian plaster. The polished and coloured surface is a tradition SINCE ancient Roman times, pozzolona dust is used, that is a sand of volcanic origin and it is RESPONSIBLE for MAKING the surface polished and smooth, but you can also use marble dust or coloured pigments of quartz mixed with lime. History tells that this technique was improved during the SEVENTEENTH and Eighteenth centuries in Venice, that is the reason why it is called “Venetian”, also called Roman plaster.

The more layers of Venetian plaster are applied, the more polished and extremely refined is the wall. Obviously it also more expensive because of the labor it needs.

The correct CHOICE is (d) In measuring WATER velocity

The best I can explain: The current velocity meter allows you to measure stream flow velocity in feet or meters PER second and measure water depth in hundredths of a foot up to three feet. The AVERAGE stream flow velocity times the cross-sectional AREA of the stream determines the stream flow measurement in cubic feet or meters per second.

The correct answer is (b) Parallel-scale nomogram

Easiest explanation: The field of nomography was invented in 1884 by the French engineer Philbert Maurice d’Ocagne (1862-1938) and used extensively for MANY YEARS to provide engineers with fast graphical calculations of complicated formulas to a practical precision. Nomograms use a parallel coordinate system invented by d’Ocagne rather than standard Cartesian coordinates.

A nomogram consists of a set of n scales, one for each variable in an equation. Knowing the values of n-1 variables, the VALUE of the unknown variable can be found, or by fixing the values of some variables, the relationship between the UNFIXED ones can be studied. The result is obtained by laying a straightedge across the KNOWN values on the scales and reading the unknown value from where it crosses the scale for that variable. The virtual or drawn line created by the straightedge is called an index line or isopleth.

Correct answer is (d) Grads

For explanation I would say: The gradian is a unit of measurement of an angle, EQUIVALENT to 1/400 of a turn, 9/10 of a degree, or π/200 of a radian.

It is also known as gon (from Greek γωνία/gōnía for angle), GRAD, or GRADE. In continental Europe, the FRENCH term centigrade was in use for one hundredth of a grad. This was one REASON for the adoption of the term Celsius to replace centigrade as the name of the temperature scale.

Right answer is (b) Tolerance

For explanation: For ADDING tolerance in AutoCAD dimensions, you can create a new dimension style with tolerance values and settings. This dimension style containing tolerance values can be applied WHEREVER TOLERANCES are required.

To make a dimension style with tolerances, TYPE “D” or “DIMSTYLE” on the command line and press Enter. The Dimension Style Manger window will pop up. CLICK on the New button from this window, give your new dimension style a name and click on the Continue button. For example, I will name this dimension style “Tolerance Dim.”

Correct answer is (b) per lb

Best explanation: Drilling and Blasting is the CONTROLLED use of explosives and other methods such as GAS pressure blasting PYROTECHNICS, to break rock for excavation. It is practiced most often in mining, quarrying and civil engineering such as dam or road construction. The result of rock blasting is often known as a rock cut.

Drilling and Blasting currently utilizes many different varieties of explosives with different compositions and performance properties. Higher velocity explosives are USED for relatively hard rock in order to shatter and break the rock, while low velocity explosives are used in soft ROCKS to generate more gas pressure and a greater heaving effect. For instance, an early 20th-century blasting manual compared the effects of black powder to that of a wedge, and dynamite to that of a hammer. The most commonly used explosives in mining today are ANFO based blends due to lower cost than dynamite.

The correct choice is (c) per % nos

Best explanation: In a large industrial brickworks, clay is taken from the quarry, and then carried by conveyor belt or truck/lorry to the main factory, although it may be stockpiled outside before entering the machinery. When the clay enters the preparation plant (Clay Prep) it is crushed, and MIXED with water and other additives which may include breeze, a very fine anthracite that aids firing. This process, which is ALSO known as pugmilling, improves the consistency, firing QUALITIES, texture, and colour of the brick. From here, the processed clay can be extruded into a continuous strip and cut with wires, or put into moulds or PRESSES (also referred to as forming) to form the clay into its final SHAPE. After the forming or cutting, the bricks must be dried, either in the open air, in drying sheds, or in special drying kilns. When the bricks have been dried, they must then be fired or ‘burnt’ in a kiln, to give them their final hardness and appearance.

Correct choice is (a) per litre

The explanation is: Paint is any liquid, liquefiable, or mastic COMPOSITION that, after application to a substrate in a thin LAYER, converts to a solid film. It is most commonly used to protect, color, or provide texture to objects. Paint can be made or purchased in many colors—and in many different types, such as WATERCOLOR, synthetic, ETC. Paint is TYPICALLY stored, sold, and applied as a liquid, but most types dry into a solid.

The correct choice is (c) Nomographs

To EXPLAIN: A nomogram (from Greek νόμος nomos, “law” and γραμμή grammē, “line”), also called a nomograph, alignment chart or abaque, is a graphical calculating device, a two-dimensional diagram designed to allow the approximate graphical computation of a MATHEMATICAL function. An arrangement of two linear or logarithmic SCALES such that an intersecting straight line enables an intermediate values or values on a third scale to be READ off.
