Task (1)

You work as a material engineer at an aircraft development, manufacturing and maintenance company in the MENA region. Recently, the manufactured airplanes have been experiencing crashes after a couple of years in service. You have been assigned as a member in the investigation team to identify the main cause of the crashes.

1. The shape of the designed windows of the manufactured planes is square. The investigation team suggested that this design might be the main cause of the crashes. You must provide a possible explanation of the investigation conclusion from an engineering point of view.

2. Write the properties that should be considered when designing and manufacturing the coroners of the windows from an engineering point of view.

3. You have been given a sample of a malfunctioned airplane wing, which is made of aluminium. The company offered you an access to a tensile testing equipment and magnetic particles inspection equipment to investigate the malfunctioning behaviour. The results of your experiment were as follows:

Table 1: Tensile Testing Results (Load Extension)

1. Given that the length of the sample is 90 mm and the diameter of it is 7 mm.
   1. Draw the stress stain diagram.
   2. Find the yield stress (in KN/mm²).
   3. Find the ultimate tensile stress (in KN/mm²).
   4. At a point on the proportional section, calculate the modulus of Elasticity (Young’s modulus).

Hint: when calculating the Elasticity, use the stress strain numbers, not the force numbers

Write a report for experimental soil mechanics? Define briefly the experiments.

Describe horizontal design of highways (horizontal curve, superelevation etc).

1. Discuss examples of the ethical considerations engineers must think about in public sector projects.

2. Discuss some differences between breakeven and payback analysis. How does this differ from other types of analysis

3. What are some methods for handling indirect cost estimation?

Please answer this engineer related question with detail. Please answer all three questions. Thank You

You need to develop a preliminary estimate for a 5” thick, Heavy Industrial, Reinforced Concrete Slab on Grade. What are the costs/SF for material, installation, and total for this slab on grade construction? What is the total cost if the slab on grade is 80,000 SF?

Q1:Compare the methods of slope stability analysis and write in your own words how the methods are different from one another.

Question 4 a) "SuDS are designed to mirnic the natural rnovement of water and slow down the process of the water getting into the watercourse. They can channel the flow of water above ground and reduce the burden on the piped sewerage system- The Pitt Review 2007. This extraction from the Pitt Review surnmarised the application of Sustainable Drainage Systerns of which there are rnany designs. Briefly explain each of the different types of SuDS noted below. i. Green Roofs ii. Balancing Ponds iii. Infiltration trenches iv. Swales v. Permeable pavements (10) b) The floods for a particular river conform to an Extreme Value Type I (i.e. Gumbel) distribution. If the 100-year flood has a magnitude of 260 ri,/s and the 10-year flood has a rnagnitude of 170 rnsVs. what is the probability of having a flood as great as or greater than 240 rn-, and what is the return period of that event. c) Give 3 examples of Human flood causes (12) (3)

RAIL AND CARBON EMISSIONS FREE WORLD

1)Improvements to enhance the carbon-free rails? 

2) Factors affecting the carbon-free emissions

• Design of the system that affects the emission rate

• Health issues due to emissions?

In the past few decades, a fourth industrial revolution has emerged, known as I.R.4.0. I.R.4.0 optimizes the computerization of I.R.3.0, where computers are connected and communicate with one another to ultimately make decisions without human involvement using autonomous systems fuelled by data and machine learning. A combination of cyber-physical systems, the Internet of Things (IoT), access to real-time data, the introduction of cyber-physical systems, and the Internet of Systems make I.R.4.0 possible and the smart factory becomes a reality. I.R.4.0 connects physical with digital and allows for better collaboration and access across departments, partners, vendors, products, and people. As a result of the support of smart machines that keep getting smarter as they get access to more data, the factories will become more efficient, productive, and less wasteful. I.R.4.0 empowers business owners to better control and understand every aspect of their operation and allows them to leverage instant data to boost productivity, improve processes, and drive growth.
I.R.4.0 had been adopted successfully in various industries especially in the manufacturing industry. However, it is rarely adopted in the water industry to date. As a new generation of civil engineers, it is important to know and understand where to adopt IR.4.0 in Civil Engineering especially in the water industry. Besides, it is also important to know the impact and challenges faced in the water industry, and how does I.R.4.0 helps to solve the problems that we are facing in the water industry nowadays.

This is a question on the “Application of I.R.4.0 in Water Industry”.

Write about,

1) Impact, advantage, and disadvantage of adopting I.R. 4.0 in the water industry
2) How does I.R.4.0 help to solve the problems in the water industry

How to size an I section under shear bending? Stress calculation should be done at which points, why? Which of the parameters that affect stress are more critical? What changes when the section is L, rectangular, or U? What additional inspections should be made for a safe design or what principles should be used for the check? How to choose the section or point to be checked? Explain with formulas, figures, and equations.
