Iam a graduate in mechanical engineering. And I was working in manufacturing field for 3 years. Now I feel like to move and work in other sections in mechanical engineering related field . Please guide me,what should I do next ? Which course should I need to learn ? I would like to work in designing field
Hello everyone! I recently graduated in industrial engineering in France, and I’m very interested in roles focused on the industrialization of new products. I’ve realized that this type of work often requires deeper technical skills than those covered in my program.
After some interviews, I found that a mechanical engineering background might be more suitable for the kind of positions I’m aiming for. I already have some basic technical knowledge, but I’m eager to deepen my understanding.
If anyone here could share more about the courses taught in this field—or even share course materials—I would really appreciate it! Thank you!
I've modelled many models in fusion 360 and solidworks (cylinder assembly, shell tube heat exchanger, etc). Should I be using them in my resume to prove my proficiency for an interview?
This is a newbie question for a more or less DIY application, how effective would the orange ball spring plungers be when contacting the panel at a 30° angle? The blue panel slides down into the inverted triangle frame with vertical lips on the front and back to prevent movement, will my plungers be effective at keeping the panel in place at 30°, and if not, what non-vertical angle can they operate?
Any help is truly appreciated
Hello! I've looked through this sub and a few others and haven't found many answers so I figured I'd ask: would pursuing a ME AS online be a good idea?
I myself am a hands on learner and am nervous about the idea but pictures and videos also are helpful so Im thinking I could manage! The only reason Im considering it is Im a mom and I work full time. Ive always toyed with the idea of being an engineer bc I love knowing how things work and daydreaming how to make them better. As a kid I was obsessed taking things apart and putting them back together. Ive been recently wanting an actual career and not my current draining 9-5. After my research so far I think mechanical engineering would be really good for me but my schedule prevents me from in person classes. If I convinced my brother to give up his portion of the GI Bill from our dad (hes going to enlist most likely anyways) that would open up the opportunity to have the income from that and switch to a part time job but Id still prefer online if doable.
Sorry for the lengthy rant lol just covering all the bases! Appreciate your thoughts and advice!
Hi. I'm trying to create a small steam engine. I created the basic design in OnShape - Steam Engine Assembly. It is mostly a copy of the one created in this video. My main concerns right now are the following:
Thanks!
Hello all! I am starting a progression fantasy story about an engineer transported to a fantasy medieval world. I need your help! What sorts of things should he build, repair, and make? I also want him to kill monsters with home-alone-style traps. Let me know!!
I have a BSME from an ABET accredited university. From what I've read about the Washington Accord that means my degree should be fully recognized in New Zealand and make me eligible for Tier 1 immigration status.
Is this correct?
How can I tailor my CV/resume to appeal to NZ employers?
3.a. I'm pretty quick at converting units, but I'm not in the habit of thinking in metric. Will coming from a non-metric country create any barriers for me?
3.b. Most of my work experience is in the water jet industry. Is there a preference for bar or MPa when discussing pressure?
I became a stay at home parent at the start of the pandemic. I have kept my CAD (solidworks) and FEA (solidworks simulation) skills current with 3D printing projects. Is there a preferred way to discuss this on my CV/resume?
Are there any businesses or agencies that provide guidance/assistance for potential immigrants in technical fields?
Thanks for your assistance!
Hi, I’m currently in my 3rd year of Mechanical Engineering. I’m studying in Mexico because it’s much cheaper and my family and I couldn’t even afford a state school in CA. My school is ABET accredited, so my plan is to work in the USA eventually when I graduate (I’m a US citizen), but i’m not sure if it’s relevant that my school has the ABET accreditation or not. I’ve heard it’s a really good accreditation but I’m not sure how important it is when trying to apply for my first job in the US. I’ve done 1 internship in the US, and i’m currently doing another internship in Mexico.
25M in NY with a bachelor in ME and currently working as a production engineer with 3 YOE in the aerospace industry. I think it cool and all but tbh I’m looking to switch to another industry and would like some recommendations that might be easy to transfer to from aerospace. Thank you for any suggestions
Hello , i am struggling to find the reactionary forces on 2 motor mounts. So i have a motor that is held by two mounts, one on the left and the right. The motor rotates a sprocket which turns another gear which spins the wheel. the problem i am encountering is that i am unable to correctly find the reactionary forces on each of the mounts. The motor is a Emrax 228 medium voltage liquid cooled motor which has a peak torque of 240Nm, the motor weighs 13.5 kg, each of the mounts weighs 0.98kg. The sprocket spun by the motor has 11 teeth, and the gear attached to the wheel is 40 teeth. the chain is a 520 chain. I calculated that the force on the chain is 7.3 kN but i have no clue where to go from here. below is a quick diagram of what forces i must calculate
I am looking to find relevant formulas to calculate the force i need to apply to push an insert into a bore with a known diameter difference. I asked chat gpt but the numbers there seemed way to high. The bore is made of brass and the insert is sst 316
Hi i am a fresher student, want to know which mechanical video is help for interview preparation?
Good day,
Problem: I have problem I do a lot of 3D prints and want to try to use some TPU however I have heard the fumes are not very nice.
Solution: I have decided to make a homemade air purifier for three reasons one the problem above, second I have seven cats, third I like making things.
My resources: https://discord.gg/5cyuxmxbqP - Yes its discord I didn't have a more convenient tool.
Info:
I am still new too this type of thing I am a current EE student at uni, but I am pretty mechanically strong. I have a few question and in general would like any advice anyone would like to offer. I have included my resources for anyone to look at and or use if they are doing something similar. Also this will be in my room and I am trying to keep it relatively small I want to mount it near the top of my wall.
My Understanding:
At the current moment I am looking at doing a centrifugal fan or a mixed flow design. I am looking at either an ac motor or a dc motor. I am still undecided, I want to use a HEPA filter and some kind of prefilter. I believe I want as much static pressure as possible.
Questions:
Would I want a filter on the intake and the outtake, or two on the intake, or other?
How would I cool the motors in a centrifugal design?
how would I cool the motors in a mixed flow design?
How do I keep noise down to a minimum?
Do I really need a high speed motor?
I've seen some types of inline centrifugal fans how do they compare to regular centrifugal fans?
Should I still consider axil fans??
If anyone has any ideas parts?
Lastly I am new to reddit and have never made a post before so I am sorry If I make any mistakes with reddit lingo.

I have not seen this type of spring(?) Outside of those collapsable batons. This was a cheap tool that came with some steel cable I purchased on Amazon, is this a cost saving measure? What are the pros/cons of this type of component?
Hi y'all, I am fresh out of college and after 289 applications and 12 interviews I have gotten 3 job offers in the last 4 hours. I would love any input that you all have for in picking the position. below is a little summary of each.
offer from a military supplier as a liaison engineer overlooking the production of tanks and combat vehicles. More manufacturing engineering, highest pay, best on resume in terms of ownership over different processes, but it is in a fly over state with nothing around and the company demands a good amount of overtime.
verbal offer from naval supplier as a mechanical engineer to work on nuclear sun transmission technology. Best location, most likely less pay than 1, but much slower and will not provide the best resume experience
verbal offer from automotive as a design engineer to work on body design for a large automobile. Location is very rural but a day trip from family and friends, just about same pay as 2, very busy but I'd never take work home or work overtime (asked someone who previously worked in the position)
I am incredibly lucky to get the offers and wish any fresh grad the best of luck applying because shear number of applications seems to be the way to go.
I would love to hear what anyone thinks about what position I should prefer or what might look best for future careers, i am not looking to stay for more than 4ish years currently. I am just lost because I expected the process to be a single offer where I would just end up somewhere. I am also moving with a significant other so having things to do would be a little bit of a bonus.

As the title suggests, I am wondering what classes should I take in my physics bs in undergrad that are the prerequisite for a masters in mechanical engineering.
I’ve looked on line for prerequisite courses for such program but no website has that information available, at least to my knowledge.
Point is it would just be easier if someone could elaborate on their experience so that I don’t have to go through more trouble finding what I want.
What specific classes are a masters in mechanical engineering program looking for as prerequisite courses.
Up to my knowledge its fluid mechanics, material mechanics and thermodynamics
Are design classes also necessary?
I'm transitioning to this new field and I would be so grateful to know any books, videos, courses and any personnel experiences you have in HVAC and piping of yachts. Thank-you so much.
How do I go about designing mounting for a ship made of composite material. I can't drill into. Please help and share experiences or ideas or resources. Thank-you kind engineers. 🙏
I want to be an engineer, I haven't had any education since high-school and I was terrible at math but fell in love with the problem solving and general knowledge in the industry I'm currently working in. I need an insane amount of refreshing in math but I have no idea where to start, any guidance or help of any kind would be appreciated.
Hi everyone. I have some questions,
-What classes did you take your first/second year of M.E?
-What did you wish you learned when you had plenty of time?
-How did you plan your schedule and graduation?
Thanks!
I am a mechanical engineering student, and I am taking a Design of Machine Elements course this semester. We are required to complete a project and present it at the end of the term. Our instructor has asked us to find a unique mechanism, machine, or system and perform stress and fatigue analysis on it. Can you give me some idea about this.
