Post-grading feedback Lab 2

Procedure:

- It was possible to see that location 1 gravel and location 2 mud have unsaturated and saturated 'sub-layers'

- Total Stress = [Unit weight of material in layer] * [Material Layer Thickness]

- Effective Stress = [Total Stress] - [Specific Weight of Water] * [Saturated Material Layer Thickness]

Chart:

- Profile - should be a continuous line or curve

 - Profile - do not use Trendline (Layout Analysis tab); this feature is not intended for our type of Labs. Use Chart types from Design Type tab.

- When you produce datapoints for your chart please use and leave Excel formulas so we can see how you obtained them

- Axis title and labels should be on the same side if possible

Format:

 - When preparing a table for a chart please keep it formatted, e.g, borders, headings, column names etc. Points will be deducted in the "Format and clear organization of the entire document and its parts" line

- Equations as ∑ _(i=1)^n  γ_i Z_i = γ_1 Z_1 + γ_2 Z_2 + γ_3 Z_3….+ γ_n Z_n  are not in any accepted notations and are not intelligible. Notations as σ(v) = Y(1)Z(1) + Y(2)Z(2) +Y(3)Z(3) are slightly better but still, have ambiguity, and may not be understood properly by a person distant from this specific lab and lecture[k1] .

- Reminder to use named cells

Memo:

- Keep Memo language formal, avoid "like", "kind", "us engineers",

- Grammar - write Memo in a text processor and Copy-Paste into Excel. Excel does not have the spell check capability!

- If you decide to report key equations in Memo please report factors used. E.g., F = ma, where F is force, m is mass and a is acceleration

Units:

- When establish a new data column please indicate units

- When you apply multiplication or division operator there's a good chance your units will change! Example: Unit Weight [lb/ft³] * Layer Height [ft] = Stress [lb / ft²]

Calculations:

- Don't round intermediate results

General feedback:

- - Please read the Lab instructions and the lecture materials before the Lab, come prepared!

-- Don't wait to submit  until 09:50 when many other students may overload the server and you may not be able to submit successfully

-- Charts have a random place on a chart Quest[k2] 

-- Reporting units, please avoid extraneous symbols, e.g., (psf_)

- Please check if your new suggestions repeat previous - don't re-submit. "Give us meaningful suggestions for improving this lab or CAEE-201". Many suggestions essentially say "Make the labs simpler"
