The mathematical model for describing the behavior of fluids is the Power-Law model, which is given as:

If
n = 1; ⇒ fluid is Newtonian Fluid.
n ≠ 1; ⇒ fluid is non-Newtonian

n < 1; ⇒ fluid is called Pseudoplastic fluids.
n > 1; ⇒ fluids called dilatants fluids.
The mathematical model for describing the ideal Plastic fluid is given as:

From the given table:
If du/dy = 0 then τ = 10 i.e. non – zero ⇒ Fluid can not be Newtonian and non-Newtonian

Further Shear stress is a linear function of du/dy, so the fluid is ideal plastic.

Modulus of rupture: It is a measure of the tensile strength of concrete beams or slabs.

Flexural strength of concrete/ Bending tensile strength of concrete/Modulus of rupture of concrete (fcr) is given by

f_cr = 0.7 × √f_ck

∴ Flexure strength of concrete is determined as a modulus of rupture.

Flexural Strength = 0.7 × √20 = 3.13 MPa

• In a weir, the component responsible for diverting water from the river into the canal is typically the crest of the weir.
• The crest is the highest point of the weir structure, and it determines the level to which water can rise before it starts flowing over the weir.
• When the water level in the river exceeds the crest level, water is diverted over the weir and into the canal or other downstream channels.
• The design and dimensions of the weir's crest play a crucial role in controlling the flow of water and diverting it as needed.

Additional InformationAbutment:

• In a weir, an abutment is a structural support or embankment on one or both sides of the channel where the weir is constructed.
• Abutments provide stability to the weir structure, resist water pressure, and help control the flow of water over the weir crest, facilitating effective water management and control.

Apron:

• An apron in a weir is a downstream extension of the structure designed to dissipate energy and prevent erosion.
• Positioned below the weir crest, the apron helps regulate water flow, minimizes turbulence, and protects the foundation from scouring.

Headwall:

• A headwall in a weir is a vertical or slightly inclined structure placed at the ends of a spillway or open channel to guide and contain the flow of water over the weir.
• It helps prevent erosion, ensures uniform flow patterns, and enhances the weir's hydraulic performance.

When a prism is placed with its base on a horizontal plane in a CAD drawing, it can have four positions or orientations. These are:

• The base of the prism can be placed flat on the horizontal plane.
• The prism can be rotated 90 degrees clockwise about an axis perpendicular to the base, so that one of its lateral faces is touching the horizontal plane.
• The prism can be rotated 180 degrees about an axis perpendicular to the base, so that the opposite face of the base is touching the horizontal plane.
• The prism can be rotated 270 degrees clockwise about an axis perpendicular to the base, so that another lateral face is touching the horizontal plane.

Each of these positions will have a different appearance in a CAD drawing, and it's important to choose the correct orientation depending on the requirements of the design.

First, determine how many hours each labourer works:
They work from 9 a.m. to 6 p.m. which is 9 hours of work.
Then, since each labourer charges Rs. 50 per hour, find out how much each labourer earns in a day:
9 hours × Rs. 50/hour = Rs. 450
Since there are 3 labourers:
3 labourers × Rs. 450 = Rs. 1,350

So, the total charges given to three labourers for their earthwork excavation is Rs. 1,350.

Concept:

Least count of Theodolite (LC) = s/n

Where,

s = length of one division in main scale, and n = no of divisions in Vernier scale

The Circular main scale is divided into degrees and each degree is divided into 4 equal parts.

This implies that length of one division in main scale is 1/4 i.e. s = 1/4

S = = =

Given:

LC = 0.005 degrees × 3600 = 18 seconds

Calculation:

LC = 18 =

∴ n = 50

Main scale division is divided into 50 vernier scale divisions.

Zone of Rock Fracture is further divided into two zones:

1. Zone of Aeration
2. Zone of Saturation

Zone of Aeration is further divided into three zones:

1. Root soil water zone
2. Intermediate zone
3. Capillary water zone

Hence, the saturation zone does not come under the zone of aeration.

Concept:

Factor of safety for tension member is given by,

FOS = yield strength/Design strength

Calculation:

Given,

Area of tie member = 5 × 8 = 40 mm²

Design strength of tie member = (80 × 10³)/40 = 2000 MPa

Yield strength of tension member = (125 × 10³)/25 = 5000 MPa

FOS is given by, FOS = yield strength/Design strength

FOS = 5000/2000 = 2.5

Concept:

Degree of Statical Indeterminacy:

• The DEGREE OF STATIC INDETERMINACY (DSI) is the number of redundant forces in the structure.
• Redundant forces are the forces that cannot be found by writing and solving only the equations of equilibrium. They must be independent.
• Therefore, the degree of static indeterminacy (DSI) represents the difference between the number of static unknowns (reactions and internal forces) and the number of static equations (equilibrium equations).

​Mechanism:

• If the segment of a beam or any other structure between plastic hinges is able to move without increasing the load, then it is called a mechanism.
• If a mechanism is formed then it means that the structure becomes unstable.

In plastic analysis to make the statically indeterminate structure a determinate structure, the number of plastic hinges required is "j", where "j" is the degree of static indeterminacy. Further, to make a mechanism, i.e. to make a structure unstable on a statically indeterminate structure, the number of plastic hinges required = j + 1, where j is static indeterminacy.

So the correct answer is Option 3

Concept:

U-tube manometer:

• The U-tube manometer is a U-shape bent glass tube, whose one end is open to the atmosphere and other end is connected to a section where the pressure of the liquid is to be measured.
• The U-tube manometer is filled with a liquid whose specific gravity is more than as compared to the liquid whose pressure is to be measured.

• The gauge pressure at point B in the above-shown U-tube manometer is calculated by using hydrostatic law and is given as:

The pressure of liquid above section A-A in the right column = ρ₂gh₂

The pressure of liquid above section A-A in the left column = P_B + ρ₁gh₁  

Equating the above two pressure, we get the gauge pressure at point B as:
P_B + ρ₁gh₁ = ρ₂gh₂  

Calculation:

Given:

In this problem, the pressure at point B is:
Pressure of liquid above A-A in right column = 0
Pressure of liquid above A-A in left column = P_B + ρ₁gh₁ + ρ₂gh₂ 

Equating both the pressure, we get:
P_B + ρ₁gh₁ + ρ₂gh₂ = 0
P_B = −(ρ₁gh₁ + ρ₂gh₂)
Thus, option (2) is correct answer.

Defects in Timber: The defects occurring in the timber are grouped into the following five divisions:

Cantilever beam having point load at free end

At the Free end, BM = 0

The shear force developed in the cantilever beam is free to end load P.

Additional Information

Cantilever beam having point load at the middle of its length

At the Free end, BM = 0 but SF = 0.

Cantilever beam having uniformly distributed load over the whole length

At the Free end, BM = 0 but SF = 0.

∴ SF and BM are zero at the free end when the point load is at the middle of its length.

Buckling factor:

• The ratio of the equivalent length of a column to its maximum radius of gyration is known as the buckling factor.
• It is an important parameter used in structural analysis to assess the stability of slender columns under compressive loads.
• The buckling factor provides an indication of the column's susceptibility to buckling, which is a critical failure mode for slender members.

Poisson's ratio (option 1) is a material property that relates lateral strain to axial strain in an elastic material. It is not directly related to the ratio mentioned in the question.

The factor of safety (option 3) is a measure of the capacity of a structure to withstand loads beyond its expected working conditions. It is not related to the ratio of the column length to the maximum radius of gyration.

Therefore, the correct answer is option 2.

For Reaction at A and B:
R_A + R_B = 4W
Taking Moment about B
R_A × 4C - W × 3C - 2W × 2C - W × C = 0
R_A = 2W
R_B = 2W

Shear Force Diagram:

Hence, maximum shear force in the beam will be 2W.
