1. A 3.5 m clear span singly reinforced cantilever beam has a rectangular section of b=300mm and D=500
mm is reinforced with 2 bars of 32 mm diameter and 1 bar of 25mm diameter in the tension zone. The
live load taken by the beam is 19 kN/m. Check if the beam is safe to carry the above load . Use M25
and Fe500.

produce a drawing to show a cross section of track including rails, sleepers and substructure.
• on the drawing identity the requirements for ballast depth and show how the axel loading is distributed throughout the infrastructure.
• interpret the engineering standards applied by the infrastructure controller, and produce a table showing examples of  
different design requirements applicable for line speeds and gross axle tonnage.
• explain the gauging requirements of the track including the interface with OLE and /or DC conductor in terms of rail geometry.
• explain the common failure modes associated with track geometry defects.

A 600 mm diameter pipe carrying 0.9 m3/s of oil (RD 0.85) has a 90o bend in the horizontal plane. The loss of head due to the bend is 1 metre of oil and the pressure at the start of the bend is 300kPa. Calculate the magnitude and angle of the resultant force exerted by the oil on the bend.

Could a sluice gate be used as a flow measuring device?

Comment on the performance of the gate as a flow measuring device under both conditions (drowned and free)

Sustainable construction has been high on the agenda of the industry for a number of years. You have been asked to give your view on:

i. Is modern construction sustainable? You must present more than one side to a discussion of this question, finally coming to a conclusion that you support with arguments and with reference to case studies. Your case studies may range in scale and purpose.

ii. How have modern materials improved the sustainability of construction in recent years? You must include in your discussion an explanation of how this has been achieved and how successful this achievement is within the context of global sustainable development.

Which ASTM (type 1-5) cement is most appropriate for the following construction applications? What types of mineral and/or chemical admixtures could be used for each application? Give reasons for your choices: Construction of a transfer plate with a thickness of 2 metres.

Please develop at least five design notes to be provided in the construction drawing for cast-in-place reinforced concrete piles without permanent casing

a.PM2.5 is a criteria pollutant that can have immense impact to our health and visibility. It is defined using the aerodynamic diameter. But how is this diameter being defined, i.e. what is the definition of aerodynamic diameter?

b. Why is PM2.5 defined using aerodynamic diameter?

c. What is the physical meaning of relaxation time of an atmospheric particle? And explain how the relaxation time is associated with the size of the particles.

d. Impactor and cyclone are commonly used size-selection devices to separate PM2.5 particles from the particle-laden air. Describe with sketches by hands to illustrate how the separation is achieved with the impactor. Please define relaxation time and explain how the particles separated with an impactor using the relaxation time concept. Be reminded to label the sketches clearly.

Assume you are conducting a parking study in your University. You need to explain the processes/tasks that you will undertake to complete this study. You need to explain how you will do different tasks and how you will present the collected data.

A vertical summit curve has its highest point of the curve at a distance 48 m from the P.V.T. The back tangent has a grade of +6% and a forward grade of -4%. The curve passes thru point A on the curve at station 25+140. The elevation of the grade intersection is 100 m at station 25+160.

1. Compute the length of the curve.
2. Compute the stationing of P.V.T.
3. Compute the elevation of point A on the curve.

1. Explain the reasons why disputes and/or conflicts arise and ways of avoiding them on construction projects?

2. What are the benefits of Alternative Dispute Resolution you can suggest to your Client with clear examples?

3. What are the advantages and disadvantages of negotiation you found when choosing negotiation as an alternative despite the resolution method?
