Rest of week cancelled due to weather

Week 4

2/5 (T)

https://bitbucket.org/Guy_vandegrift/qbwiki/wiki/Home

Today we will try to develop test questions.

We need access to Python

1. Available on most campus computers (including our little lab laptops)
2. See also https://www.python.org/downloads/ is you want to download one on your laptop

Next we need to get Python files to improve

Start here:
https://bitbucket.org/Guy_vandegrift/qbwiki/wiki/Home

1. From the aforementioned wiki Click Source to get to:
2. Source Look in OSUP-1-5-unfinished to get chapter 5 questions. We begin with problem 33 at:
3. up1-5-33 Use the 3 dots and open raw to get to:
4. a python file you can save

Latex

If you have Windows and are willing to waste a lot of time download Miktex at: https://miktex.org/. But it is far simpler to upload the question only (after deleting the \ifkey footnote):

1. https://latexbase.com seems to work, at least for now.
2. I have no experience with https://www.overleaf.com/user/subscription/plans

W: Mit labs and meeting

2/8 Fri: Learned one wikiquiz

• Wright_State_University_Lake_Campus/2019-1/Matlab#Multiplication

Lecture:

• Did both sections do this?
• Any questions about the test?

Week 7

Differentials and energy conservation

• read
• don't read

Note dot product:

$F_{x}dx=mv_{x}dv_{x}={\tfrac {m}{2}}dv_{x}^{2}=d\left({\tfrac {1}{2}}mv_{x}^{2}\right)$

$F_{y}dy=mv_{x}dy_{y}={\tfrac {m}{2}}dv_{y}^{2}=d\left({\tfrac {1}{2}}mv_{y}^{2}\right)$

Add these equations together:

$F_{x}dx+F_{y}dy={\tfrac {m}{2}}d\left(v_{x}^{2}+v_{y}^{2}\right)$

In vector notation:

${\vec {F}}\cdot d{\vec {r}}={\tfrac {m}{2}}d({\vec {v}}\cdot {\vec {v}})=d\left({\tfrac {1}{2}}mv^{2}\right)$

In your fluid class you will deal with more complexity. But for a short distance, the velocity profile is uniform. After that, ${\vec {v}}$ must be replaced by $A^{-1}\int {\vec {v}}\cdot d{\vec {A}}$
