Guys, I need these questions to be done by the method of infinite elements. I can send two codes in Scilab for conference if necessary.
Question 1 ) Consider the structure composed of three linear bars as shown in Fig. 3.5. Given away:
Determine:
1. the overall stiffness matrix of the structure.
2. the displacements at nodes 2, 3 and 4.
3. the reaction at node 1.
4. the voltage on each bar
Question 2) Consider the second structure composed, determine:
1. the global stiffness matrix of the structure.
2. the displacements at nodes 2 and 3.
3. reactions at nodes 1 and 3.
4. the voltages in each element.

I already Done part A of this problem(I provided my answer below please find it)

I already Done part A of this problem(I provided my answer below please find it) but need help with B, C and D. To work on this task, you need a copy of the Design Manual for Roads and Bridges (DMRB) – (Table 8/4), and specification of the commercial compaction plants used for the compaction job. I PROVIDED COPY OF THESE DOCUMENTS BELOW, PLEASE FIND THEM.
A road is to be constructed using the following design specification:
-Type 1 (unbound mixture) capping layer of 365mm thickness is to be laid.
-Total length: 1500m and Width: 7.2m.
It is required to select the best compaction plant options. To do so, please complete
the following tasks:
A. Using the recommendation provided by the Design Manual for Roads and Bridges (DMRB) – (Table 8/4), select all potential options for laying the 365mm capping layer using vibratory rollers.
In the selection of each option, specify the type of roller (i.e. Compaction Plant), Mass per metre width of the roll (as provided in the table), number of compacted layers and their thicknesses, and the total number of passes required. [it is best to organise your answer in a table].
B. For each option (considered above), choose a suitable commercial roller (taken from the brochure supplied*).
[*You may alternatively search the net for other brochures of commercially available compaction rollers suitable for this job].
C. Assuming the typical average rollers speed = 2.5 km/hours, how long (in hours) the compaction job would take to be completed for each roller option. If the compaction job should be completed in no more than 3 days, select the options that can achieve this target.. [assume typical working hours per day is 8 hours, + 2 hours overtime if necessary].
D. Comment on the results and briefly discuss the factors that might influence the appraisal of your best options. And suggest (with discussion) 2 standard methods that could be used in this project for compaction quality control

I have done a road design for the below assignment (brief attaced). And want to write a short report about DRAWING PRODUCTION AND ALIGNEMNT And ROAD ALIGNMENT for my design. The design is a link road between Acorn Way and Locko Road, Chaddesden Derby, UK.
I need short explanation report with any calculations needed.
below is a link for the road design I have done on AutocadCivil 3d(UKIE version)

3. Water at 20°C flows through a vertical sand column of length 80 cm and diamet

3. Water at 20°C flows through a vertical sand column of length 80 cm and diameter 6 cm. The median grain size of the sand d = 0.25 mm, the hydraulic conductivity K = 5.0 m/d and the porosity is 0.30. The head at the upper end of the column is 90 cm, and at the lower end it is 50 cm
Calculate and plot (on one graph) the hydraulic head (h), the elevation head (z) and the pressure head (ψ) along the column length x; set x = 0 cm at the upper end of the column and x = 80 cm at the lower end. Use units of cm for head)
Calculate the intrinsic permeability of the soil (in m2).
Is Darcy’s law applicable? Why or why not?
Calculate total water pressure (in units of psi) in the middle of the column at x = 40 cm.
If the effective porosity is 0.20, what is its travel time through the column?

1. a. Calculate the horizontal groundwater flow velocity in the sand portion of the SGZ (in ft/d). Assume an effective porosity of 0.25 for the SGZ unit.
b.Calculate the vertical groundwater flow velocity across the aquitard in the vicinity of the site (in ft/d). Assume an effective porosity of 0.40 for the aquitard.
c.What is the flow of water (in gal/d) traveling through a 400 ft wide cross section of the SGZ (sand and gravel)?
2. A groundwater basin with a surface area of 125 km2 has the following average annual measurements:
Precipitation (60.6 cm)
Evapotranspiration (46.3 cm)
Overland flow (3.4 cm)
Baseflow (10.6 cm)
There is no streamflow into the groundwater basin, and no groundwater flow either into or out of the basin.
a) Prepare a water budget for the groundwater basin, listing inputs such as recharge on one side and outputs on the other side. Report the inputs and outputs in units of billion gal/yr and acre-ft/yr.
b) Do the inputs balance the outputs?
c) If we included pumping wells at a total extraction rate of 20 MGD (million gallons per day), would this have a large effect on the water balance? Which component of the water balance do you think would be most affected?

Only answer sections: background and motivation (at least 1 pg of text), project objectives/scope of work (at least 2 pg of text), and project challenges (at least 1 pg of text).

Submit a project proposal for a PEDESTRIAN BRIDGE from the SoFi Stadium Parking lot to the ‘Intuit Dome’ (LA Clippers basketball Arena set to be done in 2024). Since the Intuit Dome isn’t building expansive parking lot, most people will have to park on SoFi stadium lot and cross Century Blvd to access stadium.
See the “Project Proposal Template” file attached for format. ONLY answer sections: Background and Motivation (at least 1 pg of text), Project Objectives/Scope of Work (at least 2 pg of text), and Project Challenges (at least 1 pg of text). Provide figures, templates, and photographs where applicable (doesn’t count toward page text minimum).
See attached photo to see location of pedestrian bridge, the red circle marks the location where the Intuit Dome is currently being built & the two red lines across Century Blvd marks where our proposed pedestrian bridge will be built.
Please list references.
