    • Participant Name: DEVESH SHANKAR DUPARE
    • Test Center Name: ION DIGITAL ZONE IDZ 2 WADI MIDC
    • Test Date: 15/07/2024
    • Test Time: 9:00 AM-11:00 AM
    • Subject: Water Conservation Officer
    • Qualification: Civil Engineer Diploma

    Cross-Drainage Work Type

    • The figure depicts a super passage.

    Theorem for Change of Slope in Elastic Curve

    • Mohr's Theorem II states the change of slope between any two points on a beam's elastic curve equals the net area of the bending moment diagram between those two points divided by flexural rigidity (El).

    Example of a Drier in Varnishes

    • Shellac

    Bridge Type Identification

    • The figure demonstrates a cantilever bridge.

    Cadmium Content Limit in Drinking Water

    • The acceptable limit for cadmium in drinking water, according to IS 10500-2012, is 0.003 mg/l.

    Orographic Precipitation

    • Orographic precipitation occurs when air masses encounter topographic barriers (e.g., mountains). The air is forced upward, causing cooling, condensation, and precipitation.

    Transition Curve and Super-Elevation

    • If no transition curve is available, super-elevation should be applied on the straight section and balanced on the circular curve (IRC:52-2019).

    Strength of Concrete

    • The strength of cement concrete depends solely on the water-to-cement ratio, provided the mix is workable (Abrams' law).

    Contour Lines and Slope

    • Closely spaced contour lines indicate a steep slope.

    Resolved Component of a Force

    • The resolved component of a 250N force along the x-axis, given the figure, is 85.5 N.

    Hazard and Accident

    • A hazard is a source or situation with the potential to cause harm to humans, property, or the environment, while an accident is an unplanned event resulting in harm.

    RCC Beams

    • In limit state design, the maximum strain in concrete at the outermost compression fiber is 0.0035 in bending. Failure of an over-reinforced beam is more catastrophic than for an under-reinforced beam.

    Rock Classification

    • The correct pairs for rock classification based on geological formation are: Limestone—Sedimentary rock and Gneiss—Metamorphic rock.

    Geodetic Surveying

    • Geodetic surveying considers the shape of the Earth. Surface lines are curved, and triangles are spherical.

    Waterproofing Materials

    • Bitumen felt is not a waterproofing material for concrete structures.

    Soil Classification

    • Silty gravels are denoted by 'GM' according to the Indian soil classification system.

    Stiffness Factor in Moment Distribution Method

    • For a symmetric beam with a symmetric load, the stiffness factor (K) at the center span is EI/L.

    Moment of Inertia of Circular Lamina

    • The moment of inertia of a quarter of a circular lamina with radius 'r', about an axis passing through its centroid and parallel to its diametric axis, is πr⁴/16.

    Head of Liquid and Small Orifice

    • If the liquid head from the center of the orifice is more than four times the depth of the orifice, it is considered a small orifice.

    Planning Stages in Construction

    • The typical sequential order for construction projects is Briefing, Designing, Tendering, Constructing, and Commissioning.

    Compressive Strength of Concrete

    • According to IS456-2000, the target mean compressive strength of M40 concrete at 28 days is calculated at 44.6 N/mm², with a standard deviation of 4 N/mm².

    Bracket Connection in Weld

    • In a welded bracket connection, the weld experiences direct shear stress as well as torsion.

    Water Closets in Restrooms

    • The number of water closets in a male public restroom should be one for every 25 people, up to 100 people.

    Specific Weight of Petrol

    • The specific weight of one litre of petrol, given a specific gravity of 0.7, is 6867 N/m³.
