A rivet may fail due to Bearing and
A)
Buckling
B)
Tearing
C)
Shearing
D)
Packing
A rivet in a steel joint can fail mainly in two ways: (1) bearing failure, where the rivet crushes the connected plate around the hole, and (2) shearing failure, where the rivet shank is cut across by the load. Hence the correct completion is "Bearing and Shearing". Buckling is not a typical rivet failure mode, tearing is usually a plate failure mode, and packing is unrelated here.
Depending upon the way in which the members are connected, Riveted joints mainly consist of two types : viz Lap Joint and
A)
Single Joint
B)
Double Joint
C)
Multiple Joint
D)
Butt Joint
Riveted joints are mainly classified by the way the plates are connected into two types: Lap joint and Butt joint. In a lap joint, one plate overlaps another and both are riveted together. In a butt joint, the plates meet edge to edge and are joined using cover plates (straps) with rivets. Therefore, the correct answer is Butt Joint. The other options are not the main classification types of riveted joints.
Plastering shall be measured in
A)
m
B)
sqm
C)
cum
D)
10 cum
Plastering is a surface finishing item, so it is measured by area, not length or volume. Therefore, the correct unit is square metre (sqm). Option (a) m is for length, and options (c) cum and (d) 10 cum are for volume, which are not used for plastering measurement.
For large flows in Surface drains, the best section, hydraulically, is provided by
A)
rectangular section
B)
circular section
C)
V-shaped section
D)
trapezoidal section
For large flows in surface drains, a trapezoidal section is hydraulically the best choice because it provides a large flow area with relatively less wetted perimeter, which means higher efficiency and lower resistance to flow. Rectangular sections are less economical for open-channel flow, circular sections are mainly used for closed conduits, and V-shaped sections are suitable only for small flows.
The committing, or threatening to commit, any act forbidden by the IPC or the unlawful detaining, or threatening to detain, any property, to the prejudice of any person whatever, with the intention of causing any person to enter into an agreement is
A)
misrepresentation
B)
coercion
C)
undue influence
D)
fraud
Under Section 15 of the Indian Contract Act, 1872, coercion means committing or threatening to commit any act forbidden by the Indian Penal Code, or unlawfully detaining or threatening to detain property, with the intention of causing a person to enter into an agreement. This exactly matches the statement in the question. Misrepresentation is a false statement made innocently, undue influence involves domination of will, and fraud involves intentional deception.
In which of the general processes does ‘Screening process’ included in Sewage Treatment Methods?
A)
preliminary
B)
secondary
C)
settlement
D)
biological
Screening is a **preliminary treatment** process in sewage treatment. It is used at the very beginning to remove large floating and suspended objects such as rags, sticks, plastics, and debris before the sewage enters further treatment units. It is not part of secondary, settlement, or biological treatment, which come later in the treatment sequence.
Arrange the provided pictures in the right order so that they make the most sensible story.
A)
1 4 3 2
B)
4 1 2 3
C)
4 3 2 1
D)
1 2 3 4
The most sensible sequence is 4 → 1 → 2 → 3, because picture 4 introduces the situation, picture 1 shows the next immediate development, picture 2 continues the action logically, and picture 3 gives the final outcome. Hence option b is correct. Option a (1 → 4 → 3 → 2) and option d (1 → 2 → 3 → 4) place the scenes in an unnatural progression, while option c (4 → 3 → 2 → 1) reverses the story flow and does not follow the logical sequence of events.
California Bearing Ratio (CBR) test is conducted on this layer to determine pavement thickness in modern flexible pavement construction. Identify the layer.
A)
Sub-grade
B)
Granular Sub-base
C)
Water Bound Macadam
D)
Wet Mix Macadam
The CBR test is primarily conducted on the sub-grade soil to assess its strength and bearing capacity. In flexible pavement design, the pavement thickness is determined based on the CBR value of the sub-grade. The stronger the sub-grade, the thinner the pavement can be. Granular sub-base, WBM, and WMM are pavement layers, but the CBR test in this context is used for the sub-grade.
This layer is also known as ‘Drainage Layer’ in modern flexible pavement construction. Identify the layer.
A)
Sub-grade
B)
Granular Sub-base
C)
Wet Mix Macadam
D)
Mix Seal Surfacing
In modern flexible pavement construction, the layer referred to as the 'Drainage Layer' is the Granular Sub-base (GSB). It is provided below the base course to facilitate drainage and prevent water accumulation in the pavement structure. Sub-grade is the prepared soil foundation, Wet Mix Macadam is a base course material, and Mix Seal Surfacing is a surface treatment, so they are not called the drainage layer.
The term ‘Depreciation’ is used for measuring the
A)
fall in value
B)
rise in value
C)
rate of change of value
D)
profit and loss
Depreciation means the reduction in the value of an asset due to use, wear and tear, age, or obsolescence. Therefore, it is used for measuring the fall in value. The other options are incorrect because depreciation does not mean increase in value, rate of change of value in a general sense, or profit and loss.
Mark the one alternative that is nearest in meaning to the word - Nullify
A)
Impress
B)
No effect
C)
Seclude
D)
Astound
"Nullify" means to make something legally or effectively void, cancel, or render it of no effect. Among the options, "No effect" is the nearest in meaning. The other options do not match: "Impress" means influence positively, "Seclude" means isolate, and "Astound" means amaze.
In design of Riveted Joints, the following have to be determined; (i) Number of rivets (ii) Pitch of rivets and (iii)
A)
gauge of rivets
B)
diameter of rivets
C)
strength of rivets
D)
thickness of rivets
In the design of riveted joints, the main parameters to be determined are: (i) number of rivets, (ii) pitch of rivets, and (iii) diameter of rivets. The rivet diameter is needed to ensure proper shear and bearing resistance, while gauge is a layout detail and thickness is a plate property, not a rivet design parameter. Hence, the correct option is (b).
Valuation of anything is an estimation of its value in terms of
A)
quantity
B)
money
C)
equipments
D)
materials
Valuation means estimating the worth or value of any property, asset, or item in monetary terms. In civil engineering and appraisal, value is expressed in money. The other options—quantity, equipment, and materials—are not measures of value.
The most suitable system of sewerage for Indian conditions is
A)
separate
B)
combined
C)
partially combined
D)
lateral
The separate system of sewerage is generally considered the most suitable for Indian conditions. In this system, sanitary sewage and storm water are carried in different conduits. This reduces the load on sewers and treatment plants, avoids overloading during monsoon, and is more economical and practical for Indian towns where rainfall can be heavy. The combined system is less suitable because it requires larger sewer sizes and higher treatment capacity. Partially combined is only a compromise, and lateral is not a standard sewerage system classification for this purpose.
A contract by which one party promises to save the other from loss caused to him by the conduct of the promisor himself, or by the conduct of any other person, is called a contract of
A)
guarantee
B)
indemnity
C)
bailment
D)
pledge
This is the definition of a contract of indemnity under the Indian Contract Act, 1872. In an indemnity contract, one party promises to save the other from loss caused by the conduct of the promisor himself or of any other person.
Why others are wrong:
- guarantee: a contract to perform the promise, or discharge the liability, of a third person in case of his default.
- bailment: delivery of goods by one person to another for a specific purpose.
- pledge: a type of bailment for securing payment of a debt or performance of a promise.
In a series of readings taken on intermediate points with a levelling staff of a Dumpy level, it is found that the staff readings gradually decrease from 2.110 to 0.880. This indicate
A)
Increase in RL of Intermediate points
B)
No Change in RL
C)
Decrease in RL of Intermediate points
D)
Increase in RL of BM
In levelling, for a fixed instrument position, a smaller staff reading means the ground point is higher (has a greater Reduced Level, RL). Since the readings gradually decrease from 2.110 to 0.880, the intermediate points are progressively rising in elevation. Therefore, the RL of the intermediate points is increasing. Option (c) is the opposite, (b) is incorrect because the readings are not constant, and (d) is irrelevant because the benchmark RL is not being indicated here.
In bolted joints, the combined thickness of two plates connected by bolts is known as
A)
grip length
B)
slip length
C)
bolt length
D)
torque length
In a bolted joint, the thickness of the connected plates clamped together by the bolt is called the grip length. This is the total thickness being gripped between the bolt head and nut.
Why the others are incorrect:
- Slip length: not a standard term for total plate thickness in bolted joints.
- Bolt length: refers to the overall length of the bolt, not the thickness of the connected plates.
- Torque length: not used as a standard structural engineering term in this context.
The Fore Bearing of a line AB in the Whole Circle Bearing System is 142°18'. What will be its Back bearing in the same System?
A)
322°18'
B)
284°36'
C)
232°18'
D)
52°18'
In the Whole Circle Bearing (WCB) system, the back bearing is obtained by adding 180° to the fore bearing if the fore bearing is less than 180°. Here, fore bearing = 142°18'.
Back bearing = 142°18' + 180° = 322°18'.
So the correct answer is option (a). The other options do not match the required 180° difference between fore bearing and back bearing.
The method of levelling in which the difference in elevation between two points is accurately determined by two sets of observations when it is not possible to set up the level midway between the two points is
A)
Check Levelling
B)
Reciprocal Levelling
C)
Differential Levelling
D)
Profile Levelling
Reciprocal levelling is used when the level cannot be set up midway between two points, such as when they are separated by a river or obstruction. In this method, observations are taken from both sides in two sets, and the true difference in elevation is obtained accurately by eliminating errors due to collimation, curvature, and refraction. Check levelling is used to verify earlier work, differential levelling is a general method of finding elevation differences over distance, and profile levelling is used to determine ground levels along a line.
Zoning theory is used in valuation of land in the
A)
Flat Rate System
B)
Comparative System
C)
Belting System
D)
Development System
Zoning theory is applied in the **belting system** of land valuation. In this method, land is divided into belts according to distance from a main road or frontage, and different rates are assigned to different belts. The theory recognizes that the value of land decreases as one moves away from the road frontage.
Why other options are incorrect:
- **Flat Rate System**: applies one uniform rate to the whole plot, not based on zoning.
- **Comparative System**: values land by comparing with similar recent sales.
- **Development System**: considers development potential and deducts development costs.
Therefore, the correct answer is **(c) Belting System**.
In Mizoram, Administrative Approval for all works under PWD is accorded from the Office of the
A)
Engineer-in-Chief, PWD
B)
Secretary, PWD
C)
Secretary, Finance Department
D)
Minister, PWD
In Mizoram PWD procedure, Administrative Approval for works under PWD is issued from the office of the Secretary, Public Works Department. The Engineer-in-Chief handles technical execution, while financial concurrence and ministerial approval are separate from administrative approval. Hence, option (b) is correct.
Sand Replacement method is adopted for testing WMM layer in a flexible pavement construction work in progress. What properties of the WMM layer is being tested?
A)
California Bearing Ratio
B)
Aggregate Impact Value
C)
Gradation
D)
Field Density
The sand replacement method is used to determine the in-situ or field density of a compacted layer. In WMM (Wet Mix Macadam) construction, this test checks whether the layer has been compacted to the required density. It does not test CBR, Aggregate Impact Value, or gradation directly. Therefore, the correct answer is Field Density.
Apart from riveted rectangular and pressed steel tanks, what shape of steel water tanks are commonly used?
A)
Trapezoidal
B)
Spherical
C)
Cylindrical
D)
V-shaped
Steel water tanks are commonly classified by shape. Besides riveted rectangular and pressed steel tanks, the other widely used form is the cylindrical tank. Trapezoidal and V-shaped tanks are not standard common forms for water storage, and spherical tanks are not typically used for ordinary water tanks in this context.
An aquifer confined at the bottom but not at the top is called
A)
semiconfined aquifer
B)
unconfined aquifer
C)
confined aquifer
D)
perched aquifer
An aquifer that is confined at the bottom but not fully confined at the top is called a semiconfined aquifer (also known as a leaky aquifer).
- A confined aquifer is bounded by impermeable layers both above and below.
- An unconfined aquifer has no confining layer at the top.
- A perched aquifer is a local saturated zone above the main water table, held by an impermeable lens.
Hence, the correct answer is semiconfined aquifer.
Identify the incorrect statement from the following :
A)
Bending Moment is maximum in a Cantilever beam at its end
B)
No tensile or compressive stress exists at Neutral Axis
C)
Neutral Axis of a balanced section is called Critical Neutral Axis
D)
Permissible stress is attained by the Concrete first in over reinforced sections
Option (a) is incorrect because in a cantilever beam the bending moment is maximum at the fixed end, not at the free end. At the free end, the bending moment is zero. Option (b) is correct since the neutral axis is the line where bending stress is zero. Option (c) is correct because for a balanced section, the neutral axis is known as the critical neutral axis. Option (d) is also correct: in an over-reinforced section, concrete reaches its permissible/compressive limit before the steel yields.
