AIIMS CRE Civil JE/AE Mock Test- 2 - NEET MCQ

Hence the correct answer is option A.

Hence the correct answer is option B.

In January = 18 + 22 + 25 = 65

In February = 20 + 12 + 32 = 64

In March = 40 + 10 + 13 = 63

In April = 21 + 22 + 24 = 67

In May = 25 + 21 + 16 = 62

Percentage increase/decrease:

In February = ((65 - 64)/65) x 100 = 1.54%

In March = ((64 - 63)/64) x 100 = 1.56%

In April = ((67 - 63)/63) x 100 = 6.35%

In May = ((67 - 62)/67) x 100 = 7.46%

M-S Excel is an application software created by Microsoft, which is mainly used for making marksheets etc.

Microsoft introduced an operating system named Windows on November 20, 1985. It is a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUIs). Windows is the most popular desktop operating system in the world, with 75% market share as of April 2022, according to StatCounter.

Poisson’s ratio of concrete is the ratio of transverse strain to longitudinal strain in a concrete specimen subjected to axial loads. The longitudinal strain and vertical strain are produced due to concrete volume reduction under compression load. Volume reduction of the concrete specimens is the result of crushing small aggregate sizes due to exerted loads. Poisson’s ratio of concrete is a constant for determining the stress and deflection properties of structures such as beams, plates, and shells

(ii) Characteristics strength of reinforcing steel, f_y=415N/mm²

(iii) Width, b=250mm

(iv) Effective depth, d=317mm

(v) Neutral axis factor, x_ub/d

=ϵ_c/ϵ_c+ϵ_s

=0.0035/0.0035+0.0038

=0.48

(vi) Coefficient, Qub

=k₁(x_ub/d)(1−k₂(x_ub/d))

=0.36×0.48×(1−0.42×0.48)

=0.138

(vii) Moment of resistance due to concrete,

M_uab =Q_ubf_ckbd²

=0.138×20×250×317²

=69.395kNm

Hence, the correct option is (c).

Weight density is given by weight/volume = mg/V
dimensions of m = M
dimensions of g = LT^-2
dimensions of V = L³
Hence dimensions of specific weight are ML^-2T^-2

As per IS 456:2000, clause 23.3, A simply supported or continuous beam shall be so proportioned that the clear distance between the lateral restraints does not exceed 60b or 250b²/d whichever is less, where d is the effective depth of the beam and b is the breadth of the compression face midway between the lateral restraints.

Thorns are derived from leaves of cactus. Similarly, Wool is derived from hair of Sheep.

through 'optical square' then the angle between the two points 90⁰.

Hence the option D is correct.

(M/I=σ_b/Y=E/R)

Hence the option A is correct.

Steel 0.25-1.5

Hence Ductility maximum in Wrought iron.

Hence the option C is correct.

Hence the option B is correct.

Hence the option B is correct.

Hence the option A is correct.

Pore pressure

Effective stress

If the water table rises above the ground level, the total stress and neutral stress will increase by the same magnitude, but effective stress remains unchanged.

Hence the correct answer is option C.

An isobar or pressure bulb is a stress contour or a line that connects all points below the ground surface at which the vertical pressure is the same.

An isobar is a curved spatial surface and resembles a bulb in shape because the vertical pressure at all points in a horizontal plane at equal radial distances from the load is the same.

Thus, the stress isobar is also called the ‘bulb of pressure’ or simply the ‘pressure bulb.’ The vertical pressure at each point on the pressure bulb is the same.

Hence the correct answer is option A.

Sludge digestion, also known as anaerobic digestion, involves anaerobic decomposition. This process occurs in an oxygen-free environment where microorganisms break down organic matter in the absence of oxygen. So, option 2, anaerobic decomposition, is the correct choice. This process is commonly used in wastewater treatment plants to break down organic solids, producing biogas as a byproduct.

Hence the correct answer is option A.

Hence the correct answer is option B.

Hence the correct answer is option C.

Hence the correct answer is option B.
