    • Dumpy level

    • Theodolite

    • Boning rod

    • All of these

    Correct Answer
    A. Boning rod
    Explanation
    A boning rod is a tool commonly used for checking the levels of sewer inverts. It is a long, straight rod with markings that indicate the desired level. The rod is placed in the sewer and the operator can determine if the invert is at the correct level by comparing it to the markings on the rod. The dumpy level and theodolite are not typically used for this purpose, so the correct answer is boning rod.

    For proper mixing, how much revolutions are required in a well designed mixer???

    • 35-45

    • 25-30

    • 15-20

    • 10-15

    Correct Answer
    A. 25-30
    Explanation
    The correct answer is 25-30. In a well-designed mixer, it is generally recommended to have 25-30 revolutions for proper mixing. This range ensures that the ingredients are thoroughly mixed, creating a homogeneous mixture. Having too few revolutions may result in uneven distribution of ingredients, while having too many revolutions may overmix the ingredients, potentially affecting the texture or quality of the final product. Therefore, 25-30 revolutions strike a balance between achieving thorough mixing and avoiding overmixing.

    The diameter of cold driven rivets ranges from

    • 6-12 mm

    • 12-22 mm

    • 22-32 mm

    • 32-42 mm

    Correct Answer
    A. 12-22 mm
    Explanation
    The correct answer is 12-22 mm because this range represents the diameter of cold driven rivets. Cold driven rivets are typically used in construction and metalworking industries to join two or more pieces of metal together. The diameter of the rivet is an important factor in determining its strength and suitability for a particular application. The range of 12-22 mm covers a variety of sizes that can accommodate different thicknesses of metal and provide a secure and durable joint.

    When a shaft is subjected to a twisting moment, every cross section of the shaft will be under

    • Tensile stress

    • Compressive stress

    • Shear stress

    • Bending stress

    Correct Answer
    A. Shear stress
    Explanation
    When a shaft is subjected to a twisting moment, the force applied causes the shaft to twist, resulting in a shear stress. Shear stress occurs when adjacent layers of material slide past each other in opposite directions. In this case, the force applied to the shaft causes one side of the shaft to twist in one direction while the other side twists in the opposite direction, creating shear stress within the shaft. Therefore, the correct answer is shear stress.

    According to indian standard specifications, the maximum size of the aggregate should not exceed ________ in the slump test

    • 25 mm

    • 30 mm

    • 38 mm

    • 42 mm

    Correct Answer
    A. 38 mm
    Explanation
    According to Indian standard specifications, the maximum size of the aggregate should not exceed 38 mm in the slump test. This means that during the slump test, the aggregate used should not have particles larger than 38 mm in size. This specification is important as it ensures that the aggregate used in construction projects is of a suitable size to achieve the desired workability and strength of the concrete mix. Using larger aggregates can result in issues such as segregation and difficulty in achieving proper compaction.

    The compressive strength of paving bricks should not be less than

    • 20 MN/sqm

    • 30 MN/sqm

    • 40 MN/sqm

    • 50 MN/sqm

    Correct Answer
    A. 40 MN/sqm
    Explanation
    The compressive strength of paving bricks should not be less than 40 MN/sqm. This means that the bricks should be able to withstand a minimum compressive force of 40 MN (meganewtons) per square meter of area without breaking or crumbling. This is an important requirement to ensure the durability and longevity of the paving bricks, as they need to be able to withstand the weight and pressure exerted on them by vehicles and foot traffic. A compressive strength of 40 MN/sqm ensures that the paving bricks are strong enough to endure these forces and maintain their structural integrity over time.

    Minimum gradient for flexible pavements to provide longitudinal drainage is

    • 1 in 300

    • 1 in 250

    • 1 in 200

    • 1 in 150

    Correct Answer
    A. 1 in 250
    Explanation
    The correct answer is 1 in 250. This means that for flexible pavements, a minimum gradient of 1 unit of vertical rise for every 250 units of horizontal distance is required in order to provide longitudinal drainage. This gradient allows for the proper flow of water along the pavement surface, preventing the accumulation of water and potential damage to the pavement structure. A steeper gradient would result in faster water flow, while a shallower gradient may not provide sufficient drainage.

    Mc Arthur pile is a

    • Steel pile

    • Composite pile

    • Disc pile

    • Cast in situ concrete pile

    Correct Answer
    A. Cast in situ concrete pile
    Explanation
    The correct answer is Cast in situ concrete pile. A cast in situ concrete pile refers to a type of foundation pile that is constructed by pouring concrete directly into a pre-dug hole or shaft on-site. This type of pile is formed by first excavating the hole, then placing reinforcement bars (rebars) inside the hole, and finally pouring concrete into the hole to form the pile. Cast in situ concrete piles are commonly used in construction projects where high load-bearing capacity and stability are required.

    The time factor corresponding to 25% degree of consolidation is given by

    • Pi/8

    • Pi/16

    • Pi/32

    • Pi/64

    Correct Answer
    A. Pi/64
    Explanation
    The time factor corresponding to the 25% degree of consolidation is given by Pi/64. This means that it takes a certain amount of time for a soil sample to undergo 25% consolidation. The smaller the time factor, the faster the consolidation process. In this case, Pi/64 indicates a relatively faster consolidation process compared to the other options.

    The least size(Dia) of a reinforcement can be (theoretically) :

    • 5 mm

    • 6 mm

    • 8 mm

    • 10 mm

    Correct Answer
    A. 5 mm
    Explanation
    The least size (Dia) of a reinforcement can be theoretically 5 mm. This means that the smallest diameter that can be used for reinforcement is 5 mm. This is important in construction and engineering as it determines the minimum size of reinforcement that can be used to provide strength and support to structures. Using a smaller diameter may not provide sufficient strength and could compromise the integrity of the structure.

    • +5 mm

    • +10 mm

    • +15 mm

    • +20 mm

    Correct Answer
    A. +10 mm
    Explanation
    According to IS 456:2000, the concrete cover can deviate from the required nominal cover by a maximum of +10 mm. This means that the actual concrete cover can be up to 10 mm more or less than the specified nominal cover. This allowance is provided to account for any variations or discrepancies in the construction process.

    A deflecting groyne in a river is

    • Perpendicular to bank

    • Inclined towards upstream

    • Inclined towards downstream

    • Perpendicular to river

    Correct Answer
    A. Perpendicular to bank
    Explanation
    A deflecting groyne in a river is perpendicular to the bank because it is designed to redirect the flow of water away from the bank and prevent erosion. By being perpendicular to the bank, the groyne creates a barrier that forces the water to flow in a different direction, helping to maintain the stability of the riverbank.
