AIIMS CRE Civil JE/AE Mock Test- 3 - NEET MCQ

Hence, the correct option is (a)

Hence the correct answer is option A.

I.e. a1/a2 = b1/b2 = c1/c2

for a1 x +b1 y = c1

and a2x +b2y = c2

∴ m/3 = 2/1 = 2/1

⇒ m = 6

To close a selected drop-down list; cancel a command and close a dialog box Esc key shortcut key is used.

The Esc key can often be used to get you out of dialogs or dropdown lists - it generally represents the pressing of the cancel button in these cases.

The concrete gains strength due to the hydration of cement.
The concrete does not set at freezing point.
Excessive rates of heating and cooling should be avoided to prevent damaging volume changes. Temperatures in the enclosure surrounding the concrete should not be increased or decreased more than 22°C to 33°C (40°F to 60°F) per hour depending on the size and shape of the concrete element. For example, there is reduced drying shrinkage and creep as compared to concrete cured at 23°C (73°F) for 28 days.
One-day strength increases with increasing curing temperature, but 28-day strength decreases with
increasing curing temperature.

The pattern here is as follows,

Hence the required term is MORV.

• II. Cohesion

• III. Intermolecular attraction

Hence the correct answer is option A.

For a column fixed at both ends, the effective length Leff=0.5LL_{eff} = 0.5LLeff​=0.5L, where LLL is the actual length of the column.

So, the effective slenderness ratio is:

Therefore, the correct answer is:

Option C: 0.5L/r

Rivet hole diameter is calculated as:

The SI unit of kinematic viscosity is square meters per second (m²/s).
Kinematic viscosity is a measure of a fluid's internal resistance to flow under gravitational forces. It is determined by measuring the time in seconds required for a fixed volume of fluid to flow a known distance by gravity through a capillary within a calibrated viscometer at a closely controlled temperature.
Hence, the correct option is (A).

Durability of concrete depends on:
Cement content, Compaction, Curing, Cover, Permeability

Ctrl + X are shortcut for cut in computer. Similarly, Ctrl + C are shortcut in computer for Copy.

Iso = equal, Gonic = declination, thus isogonic lines represents line obtained from joining points of equal declination.

IS : 3101 — Aluminium collapsible tubes.
IS : 3102 — Classification of burnt clay brick.
IS : 3495 — Method of test of burnt clay brick.
IS : 3496 — Specification for dobby lags and pegs.

Hence the option C is correct.

A stalactite hangs like an icicle from the ceiling or sides of a cavern. A stalagmite appears like an inverted stalactite, rising from the floor of a cavern.

Hence the option B is correct.

Hence the option B is correct.

Hence the option D is correct.

((C₃A)=3CaO⋅Al₂O₃)

It contains 5-11% of cement.

it rapidly reacts with water

The high heat of hydration

Responsible for flash set

Hence the option A is correct.

1. Tension failure in the plates

2. Shearing failure across one or more planes and shearing failure of the rivet

3. Bring failure between the plates and the rivets.

Hence the option D is correct.

Hence the option B is correct.

Hence the option B is correct.

Hence, the correct option is (b).

Hence the correct answer is option d.

Therefore,

Hence the correct answer is option d.
