(d) List four factors that affect the time taken for primary consolidation settlement to occur.

The Standard Form of Building Contract (SBC) and the New Engineering Contract (NEC) are the two most widely used building contracts in the UK.

Time: In the SBC, project controls in terms of time may be tracked using progress reports or programmed, and time is often referred to as the contract period.

Cost: In the SBC, project controls in terms of cost are often administered via periodic payments made to the contractor based on a pre-determined schedule of payments or stage payments.

Quality: In terms of quality, the SBC necessitates compliance with specifications and tolerances specified in the contract, whereas the NEC emphasizes the contractor's obligation to provide work of the requisite standard to accomplish the works' outcomes.

Parties' interests: The SBC's project controls are often weighted in the employer's favor, with little power given to the contractor, while the NEC provides greater flexibility in decision-making and negotiation between the parties.

Substantive Entitlements: These are the rights given to the parties under the contract and will be related to a party's entitlement to payment or the ability to terminate the contract. This is to ensure that both parties receive a fair deal.

Procedural Entitlements: These are procedures that need to be followed in the event of a dispute or disagreement over the contract's substantive terms.

SBC and NEC have their differences in terms of project control, and they are both commonly used building contracts in the UK.

To determine the production based on the number of hauling units used, it is essential to understand the concept of hauling units in a production system.

The hauling units refer to the trucks that transport materials from one location to another in the production process. They are vital in ensuring that the materials are moved efficiently from one point to the next to keep the production process running smoothly.In a production process where the loader controls the production, the number of hauling units used can have a significant impact on the overall production levels. This is because the loader can only load a certain amount of material onto a truck at a time. If there are not enough hauling units available to transport the material, it will cause a bottleneck in the production process and slow down production levels.

With the loader controlling the production and an extra truck added to the formula, there is always a truck waiting at the loader. This means that there is no downtime in the production process, and materials are continually being transported from one point to another to keep production levels at maximum capacity. In this case, the production levels will be dependent on the efficiency of the loader and the number of hauling units available to transport the material efficiently.

The Rayleigh-Ritz Method is a powerful tool for calculating the shape of the deflected curve for the beam. This method uses a series of trial functions to approximate the shape of the beam's deflection. Once the shape of the deflected curve has been approximated, the shear and moment diagrams can be determined.

Let's see how the Rayleigh-Ritz Method can be applied to the two functions given in the question. a.) u(x)=-c0 sin (πx/L)We can use the following trial function: u(x) = a0 + a1x + a2x² + a3x³ + a4x⁴Using this trial function, we can find the coefficients a0, a1, a2, a3, and a4 that will approximate the deflection function. The coefficients can be found by minimizing the following energy functional:

E = ∫₀^L [M(x)u'(x)² - V(x)u(x)²] dx where M(x) is the bending moment and V(x) is the shear force. We will assume that M(x) = EIu''(x) and V(x) = -EIu'''(x). The Rayleigh-Ritz Method requires us to choose trial functions that satisfy the boundary conditions. For this problem, we have u(0) = u(L) = 0. Plugging the trial function into the boundary conditions, we get:

a0 = 0 and a0 + a1L + a2L² + a3L³ + a4L⁴ = 0Using these boundary conditions, we can find the coefficients for the trial function. The deflection function can be approximated as follows: u(x) = -c0 [2(1-4/pi²) sin (πx/L) + 2/3 sin (3πx/L) - 4/pi² sin (5πx/L) + ...]Using this approximated deflection, we can calculate the shear and moment diagrams for the beam.

Tied columns are used when there is a lack of space, limited headroom, or heavy lateral loads on the structure. They can be designed to withstand any amount of compressive stress, and the ties help keep them from buckling.

Given DL = 500 KN, LL = 650 KN, fc' = 20.7 MPa, fy = 276 MPa, pg = 0.03, 25 mm Ø main bars, and 10 mm Ø ties, here's how to design a tied column:

Step 1: Find out the factored load. The total factored load on the column is calculated as follows: Pu = 1.2DL + 1.5LLPu = 1.2 × 500 + 1.5 × 650Pu = 1460 KN

Step 2:  The radius of gyration, r, is determined by: r = (0.5 × diameter)/square root of area We have to take the larger value for L in this case since it is greater than the smaller value. Therefore: Effective length, Le = 3 meters Radius of gyration, r = 7.07 cmK = (3m / 7.07cm)K = 42.43

Step 3: Calculate the effective length. The effective length of a column is found using the following formula :L = (K * r)The effective length is found by substituting the values into the equation: L = 42.43 * 7.07L = 300 cm.

Step 4: Determine the minimum and maximum steel ratios.  The minimum steel ratio for a tied column is 0.008. The maximum steel ratio is 0.4.

Step 5: Check for minimum steel percentage. The minimum steel percentage is calculated using the following formula:ρmin = 0.008 * (fc' / fy)ρmin = 0.008 * (20.7 / 276)ρmin = 0.0006The calculated steel percentage of 0.01 is greater than the minimum requirement, thus, it is okay. So the column design is okay.

The radius of the brass alloy specimen is determined to be 6.890 mm.

Let's begin by applying the formula:

Stress = Force / Area

and

Strain = Extension / Original Length

The given data:

Original length of cylindrical specimen of brass alloy = 92 mm (3.622 in.)

Force applied (F) = 92000 N

Extension (e) = 4.60 mm (0.1811 in.)

Stress-strain curve is given in the figure below:

Animated Figure 6.12 [Credit: T. Ahrens, Essentials of Materials Science and Engineering, 2nd edition (Prentice Hall, Upper Saddle River, NJ, 2008)]

To determine the radius of the specimen, we need to find the cross-sectional area of the cylindrical specimen of brass alloy. Since the material is isotropic (properties in all directions are same), the stress will be the same in the radial direction as it is in the longitudinal direction. So, the stress-strain curve remains the same for the radial and longitudinal directions.

Hence, stress in the radial direction,

σ = Force / Area = F / [πr²]

Where, r is the radius of the cylindrical specimen.

The elongation is given by,

Strain = Extension / Original Length = e / l

Substituting values in the above formula, we get;

σ/E = (ln(ε+1))

(σ/E) = ln (1+ε)

So,

σ = E * ln (1+ε)

Where,

E is the modulus of elasticity (Young's modulus) of the brass alloy. From the given figure;

Young's modulus (E) = 103 GPa = 103 x 109 N/m² = 103 x 103 N/mm²

When strain is 0.006, ln (1+ε) is 0.005987.

So,

σ = 103 x 103 x 0.005987 = 618.361 N/mm²

Area of cross-section,

A = F / σ = 92000 / 618.361 = 148.70 mm²

Area of cross-section of cylindrical specimen,

A = πr²

πr² = 148.70 mm²

r² = 148.70 / π

r² = 47.35mm²

r = 6.890 mm

The radius of the specimen is 6.890 mm.

Reducing the grain size in a metal increases its strength by inhibiting the dislocation of grains and enhancing grain boundary strengthening. This is achieved through a larger surface area and increased number of grain boundaries. Consequently, smaller grain sizes contribute to improved mechanical properties and increased strength in pure metals.

i) What is meant by the terms 'grain' and 'grain structure' for a metal?

Grain: A grain refers to the crystalline lattice that represents the three-dimensional arrangement of atoms in a metal. It is formed when atoms combine and create a distinct crystal structure. The average size of grains is typically a few microns, but it can vary based on the manufacturing process. Metals cooled slowly exhibit well-defined crystal structures, while rapid cooling or cold working produces a finer grain structure.

Grain structure: Grain structure refers to the size, orientation, and arrangement of grains in a metal. The boundaries between grains are called grain boundaries, which play a crucial role in the mechanical properties of the metal. The sizes, shapes, and orientations of grains can significantly impact the metal's properties and performance.

ii) Why does reducing grain size increase the strength of a pure metal?

Reducing the grain size in a metal results in an increased total number of grains. This, in turn, leads to a larger surface area in contact with neighboring grains and an increased presence of defects at the grain boundaries. These defects, known as grain boundary strengthening, enhance the metal's strength by impeding the dislocation of grains when subjected to stress.

The dislocation of grains occurs when atoms slide and slip over one another. Having more grains inhibits these dislocations, thereby increasing the metal's strength and hardness. Consequently, reducing the grain size is effective in enhancing the strength of a pure metal.

Advances in architectural achievements thrived during the Aegean and Greek eras, creating visual inspirations still used today. Let's investigate the progress of architecture and describe the development of architecture in this time period.

Aegean Architecture: The Aegean era, which includes the Minoan and Mycenaean cultures, thrived between 2500 BC and 1200 BC, significantly before the Greek era, and is believed to have laid the foundation for Greek culture. In general, the Aegean architecture is characterized by a preference for curved lines, rounded corners, and bright colors, with a strong emphasis on nature and its surroundings.

Minoan palaces, like the one depicted below, were the most impressive structures of the time. The Knossos palace in Crete is an example of one such palace, which boasted a labyrinthine layout that was intended to be both practical and aesthetically pleasing, with various colors and patterns. It had a number of fortified walls and towers, as well as a large central space, the megaron, which was the palace's focal point.

Greek Architecture: Greek architecture is often split into three categories: Archaic, Classical, and Hellenistic. This time period lasted from approximately 700 BC to 30 BC, and it was marked by significant technological advances and the development of complex designs.

Cantilever retaining walls are a prevalent type of retaining wall that is commonly used in civil engineering for a variety of applications. The walls are often used to retain soil on sloping terrain, support large structures on steep hills, and even to create terraces on steep terrain. However, the conventional pile and cantilever retaining wall design may not be the best approach to use in certain circumstances.

Here are a few techniques that can be used to construct a cantilever retaining wall.1. Soil nailing - This is a technique that is commonly used to reinforce soil and rock formations.

The process involves drilling holes into the soil, inserting a steel reinforcing bar, and then injecting grout into the hole to bond the bar to the surrounding soil.

Soil nailing is an excellent technique for retaining walls because it is relatively simple to install and is cost-effective.2. Reinforced concrete - This is another popular method for constructing cantilever retaining walls. It involves pouring a concrete wall that is reinforced with steel bars.

The concrete is poured into a form that is placed on the ground, and then the steel reinforcing bars are placed in the form before the concrete is poured. The concrete is then allowed to set, and the form is removed.

Compressive strength, impact resistance, and plastic shrinkage resistance are the most important properties of concrete. These properties are important for the durability of concrete structures. The properties of concrete can be improved by adding fibers to the mix.

Increasing the volume % of fibers can significantly improve the compressive strength, impact resistance, and plastic shrinkage resistance of concretes. The increase in volume % of fibers can result in an increase in the compressive strength of up to 30%. The impact resistance of concrete can also be improved by increasing the volume % of fibers.

The addition of fibers can increase the energy absorption of concrete and reduce the severity of impact loads. Moreover, the plastic shrinkage resistance of concrete can also be improved by increasing the volume % of fibers. This can prevent the formation of cracks due to plastic shrinkage and reduce the risk of early age cracking.

Macro-polymer fibers are useful for earthquake-resistant structures. They can help reduce the damage caused by earthquakes. The addition of macro-polymer fibers can increase the ductility of concrete, which allows the structure to deform without collapsing during an earthquake.

Yes, ESs (Expert Systems) can decrease real expertise for its users. Expert Systems are computer systems designed to imitate the decision-making abilities of a human expert in their respective fields. They use artificial intelligence, rule-based programming, and fuzzy logic to solve problems and offer advice.

When ESs are used, professionals are likely to experience less hands-on experience that can contribute to their expertise. This is due to the fact that ESs automate the decision-making process by providing answers and solutions to problems for the users. As a result, users of expert systems rely on the system to make decisions and solve problems, rather than developing their own skills and expertise. As a result, the more professionals rely on ESs, the less actual hands-on experience they gain. This is similar to a pilot who spends most of his flying time watching an autopilot system rather than flying the airplane with his own hands. Therefore, while ESs can be an excellent tool for solving problems and providing advice, they can also be a hindrance to the development of real expertise for their users.

a)To find the depth-discharge curve in the channel, we need to use Manning's equation. Manning's equation for flow through a channel is given by; $$ [tex]Q=\frac {1}{n}A R^{2/3} S^{1/2}$$.[/tex]

Where Q is discharge, A is the cross-sectional area of flow, R is the hydraulic radius, S is the slope, and n is the Manning roughness coefficient.  

Thus the depth-discharge curve in the channel is the same as that between the two reservoirs. The discharge can be calculated by substituting the respective values into the Manning's equation;

$$[tex]Q=\ frac {1}{n}A R^{2/3} S^{1/2}$$[/tex]  Here, the slope S = 0.02, and n = 0.015Thus, discharge between the two reservoirs is Given, width of channel,

Thus, the depth-discharge curve for the downstream water surface elevation of 102 m will be the same as the depth-discharge curve calculated earlier.
