Question 1

Bicycle frame was made with metal for many years manufactured. In the recent years, carbon fibre reinforced polymer is applied due to its responsiveness to fast roads and race conditions.
(a) Suggest TWO types of metal commonly used to make bicycle frame.

2. (b) List THREE advantages and THREE disadvantages of using carbon fiber reinforced polymer on bicycle frame over metal.

3. (c) Make a list to compare carbon fiber reinforced polymer with ONE types of metal in Part (a), which includes the following factors:

   1. (i) Correction resistance

   2. (ii) Strength

   3. (iii) Weight

   4. (iv) Cost

   5. (v) Manufacture

Describe the essential features of Consolidated-Undrained, Unconfined-Undrained, and Unconfined-Compression tests. Feel free to use sketches.

9. What is the importance of controlling the F/M ratio in suspended mixed activated sludge systems? What are the implications of a low or high F/M ratio to the settling properties of the biological floc? Please, elaborate your answer.

10. Why does sludge have to be stabilized before disposal? Describe the role of anaerobic bacteria on the degradation of sludge in anaerobic digesters - what is the purpose of each bacteria group in the destruction of solids/organic matter? What is the effect of pH change in the process of anaerobic digestion? Also, please describe the difference between sludge gravity thickening and air dissolved thickening process. (Please, elaborate).

Describe how a consolidated – drained triaxial test is conducted. Feel free to use a sketch to aid your explanation. What quantifies are measured during testing?

Use the annual flood data (annual maximum series) in the table below to perform a flood frequency analysis using the U.S. Water Resources Council Guidelines. The map skew for this location is - 0.2

Fill out the following table

Qu 1:
(a) Suppose that instead of always selecting the first activity to finish, we select the last activity to start that is compatible with all previously selected activities. In the case, the activities are assumed to be sorted in increasing order of start time.
Modify the Greedy_Activity_Selector algorithm to work with this approach to find a subset of maximum number of mutually compatible activities.

(b) Use the following list of activities to show how your algorithm in (a) above will work to find a
maximum set of mutually compatible activities.

Note: Show your result graphically, highlighting the selected activities with a
different color.

A vertical tangent at 4.7% intersects a tangent at -3.9% at a PVI station of 310+11.23 with an elevation of 903.00 ft. Using a vertical curve of length 493 ft., find the elevation of each full station along the curve. What is the station of the turning point on the curve? {If your calculations result in more than 6 stakes on the curve, evaluate only the first 6}.

Determine the maximum live load that a column W14x193 could support if the dead load is ten times the live load. Use A-36 with K=1 and L=22 ft.

2. You visit a track location on a high fill that is suspected of being unstable and possibly developing a slip failure. What are some of the outward signs you would look for to indicate if it may be currently unstable, or may have been so in the past? What indication or indications would lead you to believe that the slip is not recent but has been occurring over a long time?

A new 5 km long pipeline connects two reservoirs. The water surface elevation in the upper reservoir is 1100 m and in the lower reservoir is 835 m. The pipeline is 400 mm nominal diameter commercial steel with a sharp-edged inlet and includes the following flanged fittings.

10 - gate valves

19 - standard radius 90° elbows

37 – standard radius 45° elbows

8 – straight (line flow) tees

What is the maximum water flow rate between the reservoirs in m³/s?

What are the advantages and disadvantages of the flexible pavements?

Criminal Civil Research

Purpose: To search the internet for case information and then be able to compare and contrast between civil and criminal law cases.

Outcome: You will be able to apply research rules and techniques using web-based legal research.

Look up James Arthur Ray - Arizona motivational speaker -on the internet and briefly state why/how he had both criminal and civil trials

demonstrate critical thinking skills to prioritize, anticipate, and analyze problems, and then to evaluate and implement solutions.

Select the Lightest weight W-section of A992 steel to serve as a column 30 feet long and to carry an axial live compressive load of 160 kips. The member is pinned at the top and bottom. The member's self weight is estimated at 2000 lbs. It is supported at mid-height in its weak direction. Options: 1.W8x40 2.W10x39 3.W12x45 4.W14x48 5.W14x53 6.W10x45

b. Vegetated filter strip

c. Underground detention basin

d. Catch basin insert

e. None of the listed technologies will address both water quality and quantity issues.
