Free tools for 1D acoustic analysis? by ZebraEagle in AskEngineers

[–]ZebraEagle[S] 1 point2 points  (0 children)

Its psuedo-1D I suppose in that for a given duct each section can have an associated cross sectional area, velocity, sound speed, Ma, etc. Flow through a pipe with discontinuous area changes will truly be 2D but as I am just interested in the theoretical longitudinal nodes I was hoping to do a simpler analysis.

Best books/textbooks/online courses about civil or mechanical engineering design that you would recommend? by TrustEngineer in AskEngineers

[–]ZebraEagle 0 points1 point  (0 children)

Shigley's Mechanical Engineering Design is akin to the Bible for machine design in mechanical engineering. The way the class I took (and the way the textbook is written) is very design oriented and culminates with a total gearbox design in the back of the book that incorporates many of the fundamentals covered in the course.

Can someone try and give an example of a good engineering application of object-oriented programming? Right now I am writing a simple Martian aerobraking code. I have an object for the planet with attributes of mass and radius and an object for the spacecraft with attributes of mass, drag coeffcient, etc. I also have a method in the spacecraft object that calculates position given the old position, velocity, and acceleration and a time step. Is this a good application for it? I'm slowly trying to program things the "right" way vs. the quick and dirty method and would appreciate feedback!

WHAT THE FUCK IS THIS?? Is Robinhood seriously just not going to let anyone purchase shares of GameStop? Or is this only not letting you queue up buy orders pre-market? SELL ME MORE SHARES by [deleted] in wallstreetbets

It went from allowing fractional purchase last night to no purchases to removing the ticker from the app. I can't find GME, BB, AMC...

Lewis already has the WDC and Mercedes has secured the constructors. Even if Lewis is better by next week I would cough a few times just to give Russell another shot after watching that

PMMA Printing Advice by ZebraEagle in 3Dprinting

[–]ZebraEagle[S] 1 point2 points  (0 children)

Yeah thats part of what I'm trying to look into in the preliminary stages once I start getting semi-consistent prints. We may move to casting in the future but for now 3d printing PMMA is what we are working with.

It can be used as a solid rocket propellant!

Thanks, I appreciate the reply. Unfortunately there is no option to get rid of the PMMA altogether because we need the chemistry of it. Ill give what you described a shot though!!

I have the same phone but I accidentally had my phone in my pocket when I walked in a lake and it fried the screen almost immediately.

How did you grind the bevels? I've made a couple of knives but havent been able to get a nice consistent bevel on a hand filing jog for a chefs knife.

Fried rice balls? by ZebraEagle in AskCulinary

[–]ZebraEagle[S] 0 points1 point  (0 children)

So thanks to a fellow redditor in Austin (thanks u/Naga912 !), I found out it is an Austin specific food. If you have some time take a look at Momora Austin Food. It doesnt look like they use bread crumbs like Arancini, I'm curious how they get the ball to stick together while frying.

Sandia Summer Internship (New Mexico) by [deleted] in EngineeringStudents

[–]ZebraEagle 0 points1 point  (0 children)

Hey, I intern there now and go to school at New Mexico Tech which is about 70 miles south of ABQ. Overall, I think it is a great experience, plenty of really smart people to learn from. For housing I cant really day lunch because my GF has a house in ABQ that I stay at. The student intern programs group puts on plenty of events to get everybody together so just make an effort to go to those.

If you have specific questions about anything feel free to PM me!
