true/false. General contracting firms are investigating changes in construction techniques that would permit contractors to reduce the time required to complete construction of a building, decrease the amount of raw material needed during construction, and to avoid changes that require contractors that revise blueprints and redraft working plans.

Answers

Answer 1

True, General contracting businesses are looking into ways to speed up the building process by altering the way construction is done.

Construction is a broad phrase that refers to the art and science of creating systems, organizations, or items. Its origins are in the Latin construction and Old French construction. The noun construction refers to the process of building something, whereas the verb to construct refers to the act of building. Construction refers to the methods used to create buildings, infrastructure, industrial facilities, and related operations through to the end of their useful lives. Construction normally begins with planning, finance, and design and goes on until the asset is finished and ready for use. It also includes any repairs and maintenance, expansion, extension, and improvement work, as well as the asset's eventual deconstruction, decommissioning, and demolition.

What rock may be formed by fractional crystallization of olivine and pyroxene?

Answers

Ultramafic rocks may be formed by fractional crystallization of olivine and pyroxene. Mafic: Rocks, such as basalt, that are mostly composed of pyroxenes and olivine as well as plagioclase feldspar and/or feldspathoid minerals.

Ultramafic rocks are igneous and meta-igneous rocks having a very low silica content (less than 45%), typically >18% MgO, high FeO, low potassium, and are typically made of more than 90% mafic minerals, though the words are not entirely identical (dark colored, high magnesium and iron content). Ultramafic rocks make up the mantle of the Earth. A broader definition of ultrabasic includes volcanic rocks with low silica concentration that aren't necessarily highly enriched in Fe and Mg, like carbonatites and ultrapotassic igneous rocks. Large, layered ultramafic intrusions that frequently contain distinct rock types in strata are common locations for ultramafic rocks. The chemistry of the magma from which they crystallized is not represented by these sorts of cumulate rocks. The pyroxenites, peridotites, and dunites are ultramafic intrusives. Troctolite, which contains more calcic plagioclase, is one of the rarer forms. These are classified as anorthosites. The higher parts of the layered ultramafic sequences frequently contain gabbro and norite. There are additional occurrences of phlogopite and hornblendite.

(i) a marble column of cross-sectional area supports a mass of 25,000 kg. (a) what is the stress within the column? (b) what is the strain?

Answers

A marble column with a cross-sectional area that can support 25,000 kg.

The stress inside the column is 208333.33 N/(m^2). The strain is equal to 4.166 * 10^(-6)

Taking g=10,

a) Stress = (25000*10)/1.2 = 208333.33 N/(m^2)

b) Young's Modulus of Marble = 50 * 10^9

Strain = 4.166 * 10^(-6)

Stress is defined as a force per unit area within a material that results from externally applied forces, unequal heating, or persistent deformation and that enables an accurate description and prediction of elastic, plastic, and fluid behavior in physical sciences and engineering. By dividing a force by an area, stress is expressed.

Various forms of stress exist. Shear stress is caused by forces that are parallel to and lay in the plane of a cross-sectional area of the material, as opposed to normal stress, which is caused by forces that are perpendicular to the area. The typical tension inside a bar with a cross-sectional area of 4 square inches (26 square cm) will increase if the bar is pulled lengthwise by 40,000 pounds (180,000 newtons) of force at each end.

The power transmitted by a shaft is 300 kW at 450 rpm. The maximum torque is 25% more than mean torque. The permissible shear stress for the shaft material is 42 N/mm². The twist in the shaft should not exceed 1.5° per meter length. Determine the diameter required, if a) the solid shaft b) the shaft is hollow with internal diameter is 0.5 times external diameter.​

Answers

The mean torque is given by:

T = (300 kW) / (2π x 450 rpm) = 8.2 Nm

The maximum torque is 25% more than the mean torque, so the maximum torque is:

Tmax = 1.25 x 8.2 Nm = 10.25 Nm

The maximum shear stress in the shaft is given by:

τmax = (Tmax) / (π x d^3 / 32)

where d is the diameter of the shaft.

Solving for d, we get:

d = (32 x Tmax) / (π x τmax)

d = (32 x 10.25 Nm) / (π x 42 N/mm²)

d = 28.3 mm

The twist in the shaft should not exceed 1.5° per meter length. The twist in the shaft is given by:

θ = (32 x Tmax x L) / (π x d^4)

where L is the length of the shaft.

For the given conditions, the maximum length of the shaft is:

Lmax = (π x d^4 x 1.5°) / (32 x Tmax)

Feature engineering identifies and mines specific attributes and variables of a data set to facilitate; Predictive and advanced analytics.

Feature engineering is the process of identifying and mining specific attributes and variables of a data set to facilitate various types of data analytics. The goal of feature engineering is to identify the most important and relevant information in the data and to extract and transform it into a format that can be used for predictive and advanced analytics.

Predictive analytics is a type of data analysis that uses statistical algorithms and machine learning techniques to predict future outcomes based on historical data. Predictive analytics can be used for a wide range of applications, such as forecasting sales, identifying potential fraud, or predicting customer churn. Feature engineering can help to identify the most relevant variables and attributes in the data that can be used to train predictive models and make accurate predictions.

Advanced analytics is a broader term that encompasses a variety of techniques, such as machine learning, artificial intelligence, and deep learning. These techniques can be used for a wide range of applications, such as image recognition, natural language processing, and anomaly detection. Feature engineering can also be useful in advanced analytics, as it can help to identify the most important variables and attributes in the data that can be used to train advanced models and make accurate predictions.

On the other hand, prescriptive analytics and descriptive analytics, don't rely on feature engineering as much as predictive and advanced analytics do. Prescriptive analytics is a type of data analysis that uses mathematical algorithms, optimization, and simulation to generate recommendations and make decisions. Descriptive analytics is a type of data analysis that is used to summarize and describe the characteristics of a data set. In both cases, the data is mostly used as it is, without the need of extensive feature engineering.

which type of rock is most likely to contain fossils? igneous, sedimentary, or metamorphic?

Answers

The correct response is b. sedimentary. Igneous rock, metamorphic rock, and sedimentary rock are the three basic categories of rock. Sedimentary rock preserves almost all fossils.

Sedimentary rocks are a class of rock created by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation. The mechanisms that lead to these particles settling in one location are collectively known as sedimentation. Sediment is the collective name for the tiny pieces that make up sedimentary rocks. It can be made up of biological or geological waste, such as minerals (organic matter). The formation of the geological debris resulted from the weathering and erosion of pre-existing rocks or from the solidification of molten lava blobs that volcanoes had released. Water, wind, ice, or mass movement, together known as agents of denudation, convey the geological debris to the site of deposition. The bodies and pieces of dead aquatic species suspended in water and slowly accumulating on the bottom of water bodies, primarily their shells and feces, are known as biological detritus (marine snow). Sedimentation can also happen when dissolved minerals precipitate out of water.

An internal combustion engine, steam turbine, steam engine, boiler, furnace, refrigerator, air conditioner, etc. all consume thermal energy, and the thermal efficiency is a dimensionless performance measure of such a device. Thermal efficiency, sometimes referred to as the coefficient of performance, is the proportion of the net heat generated (for heating) or the net heat removal (for cooling) to the energy input in a heat engine or heat pump, respectively (external work). While a heat pump's coefficient of performance (COP) is more than 1, a heat engine's efficiency is fractional since its output is always less than its input. The Carnot theorem places additional limitations on these numbers.

The enthalpy and relative pressure at state 3 are determined with data from A-17 for the given temperature:

[tex]h_{3}=1515.42\frac{kj}{kg} \\Pr_{3}=450.5[/tex]

The pressure ratio and the relative pressure at state 3 and state 4 are used to calculate the relative pressure at state 4:

[tex]Pr_{4}=\frac{Pr_{3}}{r_{p}}\\=\frac{450.5}{\frac{900}{100}}\\=50.06[/tex]

With the aid of interpolation and data from A-17, the isentropic enthalpy at state 4 is calculated from this value:

Engineering is the scientific application of how best to transform natural resources for human benefit. In the United States, the Engineers Council for Professional Development defines the field as the innovative application of "scientific principles to design or develop structures, machines, apparatus, or manufacturing processes, or works utilizing them singly or in combination; or to construct or operate the same with full cognizance of their design; or to forecast their behavior under specific operating conditions; all with respect to an intended function, econometric analysis, or other measurable operational parameters. The manufacture or assembly of engines, machine tools, and machine parts is sometimes a more ambiguous definition of engineering, particularly in Great Britain.

• Stair step cracks and
• Unevenness in floor, etc.

Answers

Civil engineers have been challenged by cracks in both unreinforced and reinforced concrete for the past 60 years.

This thesis makes an effort to comprehend the many forms of cracks that can form in concrete and to quantify the crack width when such information is provided about their origin. The case studies that are discussed in this paper help to sustain our understanding of the various forms of cracks. Concrete cracks are incredibly widespread and challenging to comprehend. He immediately assumes there is a problem whenever there is a crack in the wall or slab, especially if the concrete is relatively recent. The opposite is not always true. Certain kinds of fissures are unavoidable. The best a contractor can hope for is to keep the cracking under control.

5. Derive an expression for the total extension of the tapered bar of circular cross-section shown in Fig. 1.21 when it is subjected to an axial tensile load P. 1₂ W. 4₁ dx D​

Answers

Young's modulus of the bar is E. Hint: consider the slice of diameter dfx) and infinitesimal thickness dx with cross-section P d D A(x) x)4, compute its extension, and integrate the result with respect to x over the length of the bar L.

What is cross-section?Cross section means the representation of the intersection of an object by a plane along its axis. A cross-section is a shape that is yielded from a solid (eg. cone, cylinder, sphere) when cut by a plane.For example, a cylinder-shaped object is cut by a plane parallel to its base; then the resultant cross-section will be a circle. So, there has been an intersection of the object. It is not necessary that the object has to be three-dimensional shape; instead, this concept is also applied for two-dimensional shapes.Also, you will see some real-life examples of cross-sections such as a tree after it has been cut, which shows a ring shape. If we cut a cubical box by a plane parallel to its base, then we obtain a square.

John will be making these decisions based on a sound IPM management program. John, along with his agronomist, scout fields all summer to determine types of pests and infestation rates of particular pests. Based on this information, John determines what types of pest control programs to use both for insect and weed control in his corn fields.This year John tried something new. In 2 out of 5 of John's corn fields had a corn borer problem last year. So as part of John's IPM program he planted those 2 fields to corn with the Bt gene. As part of a good IPM strategy, John is on a crop rotation pattern to break the cycle of many pests that plague his area.Last years DataDate# of Borers Present5/316/1510 adults/55 plants5/31 6/1510 adults/55 plants 25 adults/55 plants45 adults/55 plants7/17/1525 adults/55 plants 50 adults/110 plants27 adults/55 plants7/18/1 8/15125 adults/55plants 155 adults/55 plants175 adults/55 plants8/1 8/159/140 adults/110 plants 29 adults/55 plants9/1 9/15This Years Data175 adults/55 plants*Data reflects the average of the 2 infected fields.9/1547 adults/110 plants 28 adults/55 plants1.
