APSC JE CE Paper 2 Mock Test - 4 - Civil Engineering (CE) MCQ

Concept:

The yield of a well means the discharge from the well excavated through the given aquifer

Q = nv_a A = KiA

where,

n = porosity

v_a = the actual flow velocity of groundwater

A = the area of the aquifer opening onto the wells

K = the permeability of the soil

From the above relation, we can say that yield of a well (Q) is directly proportional to flow velocity, area of aquifer and permeability of soil.

Option is A. 2.0 m

Shrinkage ratio- It is defined as the ratio of a given volume change in a soil expressed as a percentage of dry volume to the corresponding change in water content above the shrinkage limit.

Consistency index

Porosity- The ratio of the volume of voids to the total volume of the soil mass, i.e. (n=V_v/V)

Voids ratio - The ratio of the volume of holes to the volume of the solids., i.e., e = V_v/V_s

Hence the option C is correct.

Hence the option C is correct.

It is that portion of the slab that acts integrally with the beam and extends on either side of the beam forming the compression zone. The effective width of the flange mainly depends upon the span of beams, the thickness of the slab, and the breadth of the web. It also depends upon the type of loads and support conditions.

The effective width of the flange should not be greater than the breadth of the web plus half the sum of clear distances to the adjacent beams on either side.

Hence the correct answer is option B.

Hence the correct answer is option d.

Hence the correct answer is option D.

Hence the correct answer is option B.

Hence the correct answer is option C.

Hence the correct answer is option B.

Hence the correct answer is option C.

Where σ_cbc is the permissible compressive stress.

For M20,

The initial setting time is the period elapsing between the time when water is added to the cement and the time at which the needle fails to pierce the test block by = 5 ± 0.5 mm.

Thus, the road stones used in the construction should be sound enough to withstand the weathering action. The property of aggregates to withstand the adverse actions of weather may be called soundness.

Fat lime is also known as high calcium lime or pure lime or rich lime or white lime. It is popularly known as fat lime as it slakes vigorously, and its volume is increased to about 2 to 2.5 times that of quick lime. This lime is used for various purposes: whitewashing, plastering of walls, as lime mortar with sand for pointing in masonry work, as a lime mortar with turki for thick masonry walls foundations, etc.

Hence, the correct option is (A)

Good brick earth should contain about 20% to 30% of alumina.

It is responsible for the plasticity characteristic of the earth, which is essential in a molding operation.

If present in excess, then the raw brick shrink and warps during drying.

pH of a water sample is given by

H⁺ = concentration of H⁺ ions (mg/l)

If, pH < 7,="" it="" is="" reported="" as="" />

pH > 7, it is reported as basic

pH = 7, it is reported as neutral

This implies, the lesser the pH value, the stronger the acid is.

So, among 2 and 5,

pH = 2 represents stronger acid.

• It shall consist of top and bottom reinforcement, each with a layer of bars placed parallel to the sides of the slab and extending from the edges a minimum distance of one-fifth of the shorter span.

• The area of reinforcement per unit width in each of these four layers shall be three-quarters of the area required for the maximum mid-span moment per unit width in the slab.

• Torsion reinforcement equal to half that described above shall be provided at a corner contained by edges over only one of which the slab is continuous.
