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.
