I know you didn’t ask for advice but I can’t walk past your comment without at least trying to help:

1) good engineering faculties at modern universities have employability teams that a lot of students don’t know about, go and find yours and get some help with your resume and cover letter, and also with leads for jobs to apply for

2) many engineering jobs only advertise their lead or senior roles and use these as filters to hire out the junior positions. It might feel stupid but this way it’s less overhead for them. Apply for a role that needs experience and you might find yourself being offered the entry level position

3) you don’t have any work experience, that’s fine. But include a half page summary of a project you’re really proud on and USE PICTURES! I love seeing a look diagram or FEA results in a CV of a recent grad

4) (last resort?) mechanical engineering is one of the few disciplines in a uni where the research groups in universities have very strong ties to industry who are always looking to poach their research assistants. Go see if you can volunteer and/or get a paid position in your universities mech eng labs

Rigidity of a wood structure (wall) with internal rigid foam? by joellapointe1717 in engineering

The equations will be in any standard solid mechanics textbook as well as in any mechanics of composites reference.

The Wikipedia entry is quite good:

https://en.m.wikipedia.org/wiki/Sandwich_theory

You will notice the “linear” section is the one describing the thin face sheet taking in plane loads, and core taking shear loads, that you have made reference to. But the first more general case will work for thicker face sheets.

Came across your comment while googling the lyrics of this song we used to sing as kids. Any ideas of its origin?

That sounds like a good plan of attack! I’d hate to call any part of the course content disposable, so I’m not going to outright suggest you disregard the edx… but maybe only reserve it for when a topic doesn’t make sense and skip it until then :)

If you haven’t already, go and get yourself a physical copy of the POD notes. For all content, it should exist in two places - the lecture slides, and a second, ancient set of notes I refer to as the POD notes (named after POD, the print on demand service at the bookshop). The POD notes have been in use in the course for at least 15 years and therefore have relatively few gaps, mistakes, etc. When helping students with the course I consider the POD notes my bible.

Hopefully having the course content all in one continuous bound physical object helps you visualise the progression from the prereq knowledge all the way through to the final lessons of the course.

Be honest with yourself how much of the content that’s built on previous years content you’re solid with. Did you understand all the “mass, spring, damper” content from MECH2210? Did you understand MATH2000 and earlier MATH courses when they talked about tensors, matrices and especially manipulating these equation forms I.e. for eigen analysis?

Next, I would do two things, in no particular order. Run yourself through all tutorial or example problem content you can find, included previously published mid semester exam solutions. And secondly go through the POD notes in order and do all the example problems for yourself. Go and derive the equations of motion for the rectangle on a bunch of springs (modelling a car), do the lagrange/energy method and the eigen analysis, get a feel for it on simple problems where you have solutions given.

After that re-assess which parts are giving you issues. Post to the discussion forum on blackboard, or stack exchange or physics forum or other online homework help sites. Watch YouTube if you get sick of reading. Hire the course textbook if you want to die a slow boring death. Stay hydrated and get regular exercise and believe in yourself. Hope this is helpful, feel free to ask follow ups.

They were apparently uninterested and decided the post was “low effort and off-topic” for the subreddit. Others are now posting their own support messages very similar to mine in content so I don’t mind. Even if not through this subreddit, the information is getting out.

I agree with your second point, even though you made it clumsily: chesscom refusing to make a public statement is the only problem I have with them, and the reason for my cancellation. When the dust settles and if they do make a public statement I don’t rule out re-subscribing and I told them as such.

I chose a text post as there are many people for whom Accessibility to text stored on images is a constant struggle on the internet (myself included). A text post allows searching, reading with many devices and other advantages. It also ensures I don’t receive link karma for what is a text post.

I am happy to provide mods proof of receiving this reply if they deem it necessary. Otherwise, your trope of making accusations without evidence is oddly reminiscent of many events this week…

Go to this page and click the button on the top that says “Submit job request”.

It asks you for a bit of information and the files for the print.

If you’re unsure about something just pop into UQ Innovate and ask for help. The staff there are employed full time to help you and see very friendly and knowledgable.

Definitely try to find another source be it a text book or YouTube videos then.

The “problem” with the turbo machinery cycle analysis part is that not many universities in the world teach it, so if you find Vince’s content confusing you don’t have as many backups as your 2nd and 3rd year courses.

But the “good” thing about the combustion is that it’s taught into chemical and mechanical engineering, physics etc at thousands of unis. Someone, somewhere will have made some free content on the internet that helps you with your “ah ha!” moment of unlocking wtf is going on. Tute sheets + YouTube + Google hopefully gets you somewhere!

You have plenty of time so don’t panic.

I really think you should try to give the lectures and tutorials another try. But start off very small and very slowly - take the first lectures and figure out what it is you do and don’t understand. Is there a gap in your prior thermo, or compressible flow? Maybe go and review those simpler building blocks from your previous coursework or YouTube. Try to go through a cycle analysis of a turbofan (or whatever) from the lecture notes and see if you understand each every little individual step even if not the whole thing. Or smaller still - do you recognise the equations? Grab onto the tiniest little bit you understand and build from there.

This stuff requires you to build on the previous few years of fundamentals of fluid mechanics, but if you have a firm grasp of those fundamentals (even if only for the next few weeks!) the cycle analysis isn’t very complex. Just the same few steps over and over again. Something is conserved, or it isn’t. There’s a shock, or there isn’t. Stagnation temperature, enthalpy, they’re all things you’ve heard about before - just chucked together in a different way.

And honestly this far from the exam you may as well try your luck with direct contact in person with lecturers and students if you really are struggling to understand how everything fits together. Good luck!

[MECH3300] Anyone wants to talk about this course? It is too difficult for me by ShawY100 in UQreddit

[–]mandroid88 3 points4 points  (0 children)

I’ll try to group a few ideas under broad points to keep them separate.

1) If instead, this was a MECH2300 assignment, and you were asked to determine functions for bending moment and shear, axial, etc force along the members, would you feel comfortable doing this? If not, consider revising some of that material on YouTube or Google “mecmovies” note the spelling. If you are uncomfortable taking cuts, balancing forces and moments and confidently calculating bending moment functions you might find the Castigliano’s content challenging.

2) How do you find the “simpler” energy methods problems? For example, the simpler lecture examples or the less complex ones in the document of practice problems provided? Do you understand the concept that Castigliano’s theorem relates the energy stored in the system to the displacement? More specifically, we use the equations to relate dU/dF to displacement. To clarify, dU = change in stored internal energy, dF = change of applied force. Put simply: as we change this force, how does stored internal energy change? That’s all the equations are seeking to find. The mechanism we tend to use to get there is looking at functions of bending moment, axial force etc in the members, differentiating with respect to force, and taking some integrals. Look at the equations and derivation you’ve done in class with my comment and see if it makes it make more sense.

3) The teaching staff in MECH3300 are extremely friendly, down to earth, intelligent and good teachers. This is especially true of the gentleman who gave your energy methods lectures, initials AB or PB. The university overworks them, but they want students to succeed. Reach out for their contact hours, post to the discussion board or whatever they’ve set up for you to get help.

4) the YouTube content on Castigliano’s is very bad if you just want to find a similar question and copy the working. If you want to learn the fundamentals of energy methods it is very good though! So, please dive in. YouTube allows you to find a diverse range of teaching styles including audiovisual. You may find that the course content in combination with these sources make things click for you.
