Research Project Instructions (48330) Please read the following instructions to prepare your slides for the project that you have selected for 48330. This assessment task is to encourage you to do some research and learn basic research methodologies. You may consider this task as some sort fun research work and try to enjoy the research part. Do not worry much about the mark but do your best as this is to help you to boost your marks up and have a superior experience of Soil Behaviour at UTS.

Select a topic from the U.S. Geological Survey website. Develop a research proposal for your selected topic.

Problem-5. A rectangular plate submerged in water is 5 m by 4 m, the 5-m side being horizontal and the4-m side being vertical. Determine the magnitude of the force on one side of the plate and the depth to its center of pressure if the top edge is (a) at the water surface; (b) 1.0 m below the water surface; (c)100 m below the water surface.

What phase is the moon in in each of these pictures? Name it (e.g. waxing gibbous) and provide a description (e.g. more than half illuminated, lit from the right hand side, shadow on the left)

Problem-3. A rectangular plate 5 ft by 4 ft is at an angle of 30° with the horizontal, and the 5-ft side is horizontal. Find the magnitude of the force on one side of the plate and the depth of its center of pressure when the top edge is (a) at the water surface, (b) 1.0 ft below the water surface.

Well, we know the phase of the moon (first quarter) and the time (3 am) so we should be able to determine the moon's location in the sky for this observer. We'll need to draw our diagrams...Diagram (A) tells me where the moon is based on its phase. Diagram (B) tells me where the observer is, based on the time. What does diagram (C) say? 5. What do you think? Was the moon visible at that time? Is the witness reliable?

1.Your description should include:Provide a description of the physiographic and geologic setting of your hometown. (10 pts) The city, county, and state as well as the Latitude and Longitude of the location that you considered. ) (15 pts) The physiographic section and district of your location and a brief description of this section/district (15 pts) The geologic formation(s) that are present at your location and the published description of the formation(s). (10 pts) Supporting maps showing the physiography and geology of the area with your location marked on them. Show you some online tools for accessing geologic and physiographic data and maps introduce general types of soil how they look feel and behave •learn about the real world incomings of key soil properties

Problem-8. Repeat Problem-7 where the tank is open at the top and contains water to a depth of h = 10ft.

Problem-7. The hemispherical body shown in the Figure (r 2 ft) projects into a tank. Find the horizontal and vertical forces acting on the hemispherical projections for the following cases: (a) the tank is full of water with the free surface 5 ft above A;(b) the tank contains CCI4 (s = 1.59) to the level of A overlain with water having its free surface 5 ft above A; (c) the tank is closed and contains only gas at a pressure of6 psi; (d) the tank is closed and contains water to the level of A overlain with gas at a pressure of 2 psi. Assume the gas weighs 0.075 lb/ft3.

Problem-6. A rectangular area is 5 m by 6 m, with the 5 m side horizontal. It is placed with its centroid 4m below a water surface and rotated about horizontal axis in the plane area and through its centroid.Find the magnitude of the force on one side and the distance between the center of pressure and the centroid of the plane when the angle with horizontal, 0 = 90°, 60°, 30°, and 0°.

8. It's 3 pm and the moon is in last quarter phase. Where should you look to see it? Straight up,high/low on the western horizon, high/low on the eastern horizon?

Problem-2. Find the magnitude and depth of the point of application of the force on the circular gate shown in the Figure, if h 5 ft and D = 4 ft diameter.

9. Its midnight and the moon is just rising on the Eastern horizon. What phase is it in?

Problem-4. The gate MN in the Figure rotates about an axis through N. If a= 3.3 ft, b = 1.3 ft, d = 2 ft, and the width perpendicular to the plane of the figure is 3.0 ft, what torque applied to the shaft through N is required to hold the gate closed?

Problem-1. A plane surface is circular with a diameter of 2 m. If it is vertical and the top edge is 0.5 m below the water surface, find the magnitude of the force on one side and the depth to the center of pressure.

(4.16) In one core run of 1500 mm selectedfrom cores obtained during drilling for a bridgefoundation in hard limestone, the followingcore recovery information was obtained: Determine (a) the percent core recovery, and(b) the RQD. Based on this RQD, what is the rock quality?

Calculate the specific surface of a cube(a) 10 mm, (b) 1 mm, (c) 1 µm, and (d) 1 nm on a side. Calculate the specific surface in terms of both areas and m²/kg. Assume for the latter case that ps = 2.65 Mg/m³.

The following data were obtained froma liquid-limit test on a silty clay. Two plastic-limit determinations had water contents of 23.1% and 23.6%. Determine the LL, PI, the flow index, and the toughness index. The flow index is the slope of the water content versus log of number of blows in the liquid-limit test, and the toughness index is the Pl divided by the flow index.

(2.69) Laboratory testing was performed on two soil samples (A and B) and the data is summarized in the table. Determine the USCS classification for samples A and B. Use log interpolation as necessary. Particle size analysis and Atterberg limits wereperformed for Soils C and D. Results are givenin the following table. Classify Soils C and D according to theAASHTO system. [2 pts.]
