. A simply supported reinforced concrete beam needs to be designed with the following details: Size of Beam: 350 mm x 450 mm. Effective length of Beam: 8 m. Dead Load excluding self-weight of Beam: 30.5 kN/m Reinforcement: 25 mm bars and 8 mm stirrups Effective cover to compression reinforcement: 30 mm

i. Design the beam and find out the number of bars required.

ii. Design the beam for shear.

iii. Draw the detailing of beam.

Live load = 3KN/m square.
The missing values should be assume.

A tangent section of highway has a -1.0% grade and ends at station 0+145 and
elevation 26 m. It must be connected to another section of highway that has a -1.0% grade and that
begins at station 1 + 350 and elevation 40 m. The connecting alignment should consist of a sag
curve, constant grade section, and crest curve, and be designed for a speed of 80 km/h. What is the
lowest grade possible for the constant grade section that will complete the alignment?

Form a table to summarize all the coaxial cable connectors by drawing its structure and by
specifying its features.

What is the meaning torsion of structure when it is at first mode ? please explain detailedly.

Consider a rectangular channel with a variable width b and horizontal channel bottom, a) Obtain the equation of water surface profile (dy/dx) as function of Froude number and channel width change (db/dx) in a channel transition assuming that over a short distance x, the energy losses can be neglected. b) Using the equation you have obtained, draw the water surface profile if flow is subcritical and if there is an enlargement in channel cross section b in downstream section (2) and show your results on the graph of specific energy curve (E versus y curve).

Q2 d) An advantage of timber is that members can be easily connected together, outline the considerations that should be taken into account when designing and fabricating connections between timber members.

1. Write an introduction about the thermal and mechanical properties of stainless steel and how it is suited to the construction industry

2. Write an introduction about the fire testing in stainless steel

3. identify problems situated to stainless steel e.g. cost etc

4. Write up a scope based on this topic

Explain the slurry-phase treatment, including the pretreatment, desorption, mixer deign, soil particle and specific surface.

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?
