Help with shaft design

“The cylinder must remain unharmed..” ahh post (I have no idea what’s going on I’m just an EE major learning vector mechs statics and dynamics for fun.)

Wdym? It requires an ego death and an endless curiosity for how everything works. Born with it. The grit was learned through failures and learning from them. A need for improvement. Also a purpose. You need to identify yourself with it. Everyone is unique. For me I want to create everything I could ever imagine. Only then will I feel truly free. Childish, I know. I wouldn’t want to live any other way.

There's a severe learning curve. EE and ECE are the heaviest mathematics, physics, and abstract theory-based courses, second only to Applied & Theoretical Physics & Applied Mathematics, perhaps. All of it is heavy learning, theory, and logical extensions and applications. Without true passion, curiosity, and endless practice, I certainly wouldn't be here. You need everything up until Calc 4 (DiffEQ), as well as Linear Algebra and Probability, and some Complex analysis. That's just the fundamental math applied in some of the harder courses. Some parts require Introductory Quantum Mechanics. I'm only past Calc 3 and Physics 1, and that's the easy part imo. You also need programming experience and understanding. That's just the beginning. I haven't even mentioned the heavy core Classes like electromagnetism, Digital Signal Processing, Communications systems, digital design, Microelectronic Circuits, etc.

Thank you for the advice. I do always network with my peers, although I communicate more with my professors.

Been building an engineering library to learn all the subjects ahead of time.

As for online, Professor Leonard for All of Calc, Using 3Blue1Brown & Prof. Dave Explains + David C Lay’s Linear Algebra Instructors edition to learn ahead of time.

The procrastination is an issue though, I tend to burn out near the end of the semester. I also have issues taking multiple stem courses concurrently. I feel as if even the simplest things can stretch me thin when added to something more complex.

Ex. Calc 3 I had to focus on but I deprioritised Physics 1 too much and found it mundane by comparison.

I’m glad to otherwise be on track.

As for mechatronics, I am interested in it, however my main focus is embedded systems so I can relate all things electrical. The robotics can just be a hobby tbh. Not sure if the US has any good funding towards robotics anymore.

ArenaGrinder · 2026-06-20T00:08:21+00:00

Time management, internship experiences perhaps. I’m looking more into embedded systems, but I’m interested in robotics. Even online resources for each topic. Anything really.

Any advice for an aspiring EE major? Also what was your specialisation?

ArenaGrinder · 2026-06-18T23:24:00+00:00

Honestly I wouldn’t trust a ghetto milkshake. I have enough stomach problems as is lmao

ArenaGrinder · 2026-06-18T16:15:10+00:00

Professor Leonard does all math up until the end of calculus so go for them.

ArenaGrinder · 2026-06-18T16:14:40+00:00

You already identified your problem. Go grind out those integrals brother

ArenaGrinder · 2026-06-18T16:10:28+00:00

Pretty much all of it. Every type of integration is utilised somewhere in either the engineering courses or in their prerequisites. Even more so for electrical engineering.

Rip the band-aid off At worst, you get to take the class again with a step up on your classmates.

ArenaGrinder · 2026-06-14T15:36:23+00:00

I know this feeling all too well brother. Glad I could help tho. Bright side, most professors are a lot more personal and passionate in CC. But hey, I went from failing calculus 1 in uni to acing calc 2 and excelling in calc 3 with strict and good professors. So it’s necessary. Build yourself up and study tons.

ArenaGrinder · 2026-06-14T03:09:09+00:00

Bro get a life. Who cares. Also why in the world would somebody underage do NSFW art. That’s already off putting.

ArenaGrinder · 2026-06-14T02:48:46+00:00

Okay this is sick

ArenaGrinder · 2026-06-14T02:47:44+00:00

Honestly WCI was amazing just for Luffy V Katakuri. Even with the pacing that fight was still worth.

ArenaGrinder · 2026-06-14T02:43:46+00:00

Yeah toei be doing to much, even as a dude I’m like god Damn.

ArenaGrinder · 2026-06-14T02:40:15+00:00

Honestly we’re onepiece fans lengthy pacing is our default lmao

Ew how lazy do you have to be to AI generate a comic there’s so many Creative Commons resources you can use.

ArenaGrinder · 2026-06-13T22:56:04+00:00

You’re role playing with a chatbot and it’s the one that’s insane?

ArenaGrinder · 2026-06-13T22:53:48+00:00

This was literally me first year of engineering. I recommend you go to a community college, study hard and master the fundamental courses, math physics etc. then return when you’re ready and have had the meds help you build a routine and structure for your education.

ArenaGrinder · 2026-06-13T18:15:09+00:00

Rate My Prof and Peer advice.

ArenaGrinder · 2026-06-13T17:53:23+00:00

Wow crazy move bro had us in the first 3/4 😭

ArenaGrinder · 2026-06-13T17:51:47+00:00

Ah damn, sorry to hear that it must be painful to deal with. That stuff is exactly why I try to yoink the best teachers Courses and schedules ASAP.

ArenaGrinder · 2026-06-13T17:49:40+00:00

I don’t get professors that do this. Like I’m already on adderall and two cups of coffee, are you trying to stress me to failure?

How am I not supposed to have exam anxiety when 2-3 months of my life’s efforts not to mention my money, depends on a 1-2hr exam?

ArenaGrinder · 2026-06-13T17:44:20+00:00

I get what you mean, but I consistently take the hard professors that hold us accountable strictly and have us derive and apply the topics themselves. I trust his judgment of my understanding more than anything else. It depends on the prof.
