Postcard Professor
США
Добавлен 3 ноя 2011
Postcard Professor aims to take complex ideas and boil them down to the size of a postcard. Typically, this means a video clip with about 10-12 minutes of explanation and writing. The end product can be used as a reference sheet for homework problems.
I'm a professor at Abilene Christian University, and a strong believer that examples and lectures are more useful in video format, so that students can pause, think, rewind, and watch again. I'm making these for the classes I'm teaching, but I hope that they'll be useful to engineers around the world.

Otto Cycle Analysis (constant specific heats)
Analyze the Otto cycle, which is common in internal combustion engines. After simplification of the ICE cycle to four processes, the processes are analyzed using constant specific heats, which means that gamma is constant throughout the use of the adiabatic/isentropic relations.

Basic CoolProp Tutorial (Python Thermodynamics)
Просмотров 9 тыс.Год назад
Use CoolProp, a library of functions that allows you to determine properties of various gases and liquids with ease. This video demonstrates the basic use of the PropsSI command, then uses the same command to plot constant temperature lines on a pressure-specific volume chart.

Ideal Gas Law and Compressibility
Просмотров 543Год назад
Under most normal circumstances, the ideal gas law is an excellent tool for determining the properties of a gas. However, we tend to look at odd situations in Thermodynamics. For that reason, we need to look at situations where the ideal gas law may not apply.

Bilinear Quad Element - Shape Functions
Просмотров 5 тыс.Год назад
Determine the shape functions and derivatives for the bilinear quadrilateral element. Builds off of the Galerkin Method for 2D Solids and Stiffness Matrix for 2D Solids videos. Warning: using the approximate solution may lead to numerical instability. You should always use numerical integration with at least four points (it's really not that bad).
Element Stresses for 2D Solids
Просмотров 770Год назад
Determine the elements stresses, specifically the von Mises stress, for a 2D element. The process described can be used for any element, though discussion of maximum stress on elements with quadratic or cubic strains is not discussed.
Constant Strain Triangle - Example
Просмотров 1,8 тыс.Год назад
Find the stiffness matrix for a single CST element. Follows videos covering the Galerkin Method derivation (ruclips.net/video/7bPY3kQDxJI/видео.html), the stiffness matrix derivation for a 2D solid (ruclips.net/video/v-dcwocLvaY/видео.html), and the isoparametric shape function for a CST (ruclips.net/video/zf9ucVTlGeQ/видео.html).
Constant Strain Triangle - Shape Functions
Просмотров 1,6 тыс.Год назад
Determine the shape functions and their derivatives for the Constant Strain Triangle. This is a continuation of the Galerkin Method for 2D Elements (ruclips.net/video/7bPY3kQDxJI/видео.html) and the Stiffness Matrix for 2D Elements (ruclips.net/video/v-dcwocLvaY/видео.html) videos.
Stiffness Matrix for a 2D Solid
Просмотров 1,7 тыс.Год назад
Starting from the results of the Galerkin Method, determine a form for the Stiffness Matrix for a 2D solid. Note that we have stayed general with our shape functions, meaning that our result will work for any element we come up with.

Thankyou
Does it calculate molecular viscosity and thermal conductivity as well?
Perfect for learning
Thank you so very much for the exposure and detailed explanation
Thank 😊
very nice my friend :)
Bro that what I do when selecting equivalent pump from the existing which isn't in good condition anymore on site
With mH and mC data in kg/h I'm able to get same results for Q. Thanks for the video.
sag ol kardeş
Thanks ❤
Thanks ❤
Good work
Thank ❤❤❤❤
for the beam element, shouldn't the derivative of phi have (12*x)/L^3 for V_1 and same for V_2? this would change the values when evaluating the derivate at x=L
🇮🇳🇮🇳🇮🇳🇮🇳
Thank you sir, Clear and simple.
Your videos are just special
EXCELLENT VERY VERY GOOD
how does iteration work for this?
FYI, you didn’t help simplifying it even a single bit
Thank you!
how did you transform from celsius to kelvin temperature?
Wow
Thanx....it is really simple explanation
Got it!
he upgraded the ring
you know it well,thank you.
Thank You Sir
Appreciated it a lot 🙏
is it just me, or he get the wrong power from the hot side wrong? .1kg/s * 4.18 kj/kg*k * 15K = 6.27 kW, not 10.5 kW
95-70=25
how you calculate the ho and hi ??
best explanation
Please explain if possible, the middle support (PIN) should have a resultant moment, isn't it? Because intuitively, P is pushing down, the PIN won't settle and the wall won't let move up either. So, there should be a bending effect on the PIN.
Yes, it was informative. Thank you!!!!!!!
good writing
actually we were here for you going to solve m1 and m2 re arrangment.
Who here memorized the specific heat of water?
What a great explanation. Regards!
Thank you so much ❤
The only person who explained well this topic
Nice video sir, thank you very much.
you make the whole deviation of specific heat so clear, tysm!
Excellent. What is A0, A1 AND A2 IN MOMENT EQUATION
Thanks brother
finally!!! this saved my life
Please the value of P is rather 0.1667 and not 0.22
Bro u are my savior
Thanks 🙏
Sir why Fx1 the value is more larger than the actual force?
thanx
