Question 1
(a) What are minerals? Sketch different types of mineral crystal forms and list different types of rock forming minerals. Describe with examples the importance of mineral identification in engineering applications.
(b) Differentiate three types of rocks with examples. Also, summarize their properties for engineering applications.
(c) Describe briefly the process of mechanical and chemical weathering of rocks. Draw a typical soil profile and discuss the factors controlling soil profile development.
(d) Define ‘folds', ‘faults', ‘dip' and ‘strike' and explain each of them with neat sketches. What are synclines and anticlines? Discuss the first and second rules of anticlines.
Question 2
Critically analyse "Subsurface Exploration and Geotechnical Investigation Report" (attached) with respect to the ideas learned in Week#11. The analysis should contain sections such as overview of the report, aspects included in the report and aspects missing in the report. You should also include a section covering what would you do differently if you were assigned to complete the investigation and prepare report? Total analysis should not exceed 3 A4 pages.
Provide a comparative analysis of the types of safeguards would you suggest for the company's information system.
A horizontal curve on a single-lane highway has its PC at station 124 + 10 and its PI at station 131 + 40. The curve has a superelvation of 0.06 ft/ft and is designed for 70 mi/h. What is the station of the PT?
Briefly explain how each of the following influences the tensile or yield strength of a semicrystalline polymer and why: (a) Molecular weight (b) Degree of crystallinity (c) Deformation by drawing (d) Annealing of an undeformed material
Laboratory analysis methodology to be used. Give details on the standard methods, instrument and detection limits. Standard methods for heavy metals analysis exist
A 1600 ft long sag verical curve (equal tangent) has a pvc at station 1200+00 and elevation o 1500 ft. the initial grade is -3.5% and the final grade is 6.5%. determine the elevation and stationing of the low point, pvi and pvt.
Working a problem where there are two one-story buildings of different heights next to each other. Earthquake imparts a base motion z(t) that is a cosine function. I'm given a shape function for a column of height L when deriving the EOM for each ..
what is the final dissolved oxygen concentration (in mg/L) in the waste lagoon after all of the ammonium (NH4 + ) is converted to nitrate? Recall that 4.57 mg of O 2 is need per mg of ammonium (as N) oxidized during nitirification. After all of the..
How do you find the force ratio equation to determine the maximum total load that can be applied to a truss? Given a force of a member how do you find the force ratio?
Metallurgical balance in mineral processing, Assume 2000 short tons of ore were mined, 200 tones were rejected as waste and the tonnage accepted for metallurgical treatment
Write the unit of measurement and unit of payment of following items. 1) Earthwork in excavation in foundation. 2) Framwork. 3) Steelwork in trusses. 4) Damp proof course D.P.C. 5) Cement.
the maximum degree of curvature can be at most 6.0 and the superelevation can be at most +6.0%. Design the ramp for the highest horizontal curve design speed given the constraints.
The dye appears 14 days later in an observation well 75 ft away from the injection point. Compute the seepage velocity and estimate the hydraulic gradient in the aquifer if the porosity of the soil is 42%.
