APSC AE CE Paper 1 Mock Test - 4 - Civil Engineering (CE) MCQ

Plants give oxygen during the daytime, much more than what they require, activity being maximum at mid-noon, due to the sun's effects on photosynthesis.

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

Gypsum acts as a retarder. It counteracts the fast rate of hydration (for which C₃A is primarily responsible) to prevent flash set.

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

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

Hence the option B is correct.

Hence the option C is correct.

Section modulus, (Z=1/Y_max)

where (I=bd³/12)&(y_max=d/2)

Now

(Z=(bd³/12)/(d/2)=bd²/6)

Hence the option B is correct.

∑Fy=0)

(R_A⋅R_B=0)

(∑M_B=0)

(R_AL−M=0)

(R_A=M/L and R_B=−(M/L))

Consider a section XX at a distance x from end B Shear force (S_A−B=M/L)

Bending moment (M_x=W_x)

Hence the option D is correct.

(=100×100×1/A×200×10⁹(m))

(A=π/4(d²)=π/4×(10×10⁻³)²m²)

(=7.85×10⁻⁵m²)

( Elongation =10×1000×1/7.85×10⁻⁵×200×10⁹)

(=6.369×10⁻⁴m)(=0.64nm)

Hence the option C is correct.

Hence the option C is correct.

Hence, the correct option is (b).

Hence the correct answer is option B.

 Given,
Mean Velocity (V) = 1 m/s
Silt factor (f) = 1
Let We know that, Hydraulic mean radius as per Lacey's theory is given as:

The shear strength of cohesionless soil is reduced as the water pressure inside the pores of the soil mass increases. Experimentally, a series of consolidated drained triaxial tests with back pore water pressure was run on samples of saturated uniform dense sand.

Hence the correct answer is option B.

Hence the correct answer is option D.

reaction time t = 0.8 sec

length of vehicles L = 5 m

space s = 0.278 Vt + L

= 0.278 x 45 x 0.8 + 5

= 10.008 + 5

= 15.008 m

theoretical capacity C = 1000V/S

= 2998.4

= 2998(say)

So theoretical capacity C = 2998 vehicles/hour/lane

Hence the correct answer is option B.

To measure the discharge over the broad-crested weir, two heads (i.e., H and h) need to be measured. However, experiments have shown that the flow adjusts itself to have maximum discharge for the available head. The downstream head over the weir can be computed mathematically by differentiating equation (1) with respect to and equating it to zero i.e.

This value of h is known as depth of flow.

Hence the correct answer is option B.

Hence the correct answer is option B.

For a perfectly cohesionless soil, C = 0

If the soil normally consolidated (N.C. soil)

For overconsolidated soil (OC soil)

Where, (μ) = poisson's ratio (ϕ)= friction angle (I_P) = plasticity index

O.C.R. = Over consolidated ratio

Hence, the correct option is (C)

Hence, the correct option is (A)
