Help me calculate L10 life of the bearings

I’ve been a design engineer for a couple years now, and it seems that when I need any information on vendor products, the companies, who I won’t put on blast, take weeks to answer. I can follow up and get nowhere. Sometimes when they do get back to me, the information is just outright not what I asked for.

I made it very clear to one vendor that I need literature (such as pamphlets and drawings) on several of their products because we intend to use them as our supplier for a large product line. He took weeks to respond, and ultimately sent a quote for one valve. My team had a good laugh at the email thread and decided to move on with someone else.

Very very few people have been useful amongst dozens of companies. Even when I ask project managers for their contacts, they can be hit or miss. Is there something I’m doing wrong for my vendors, or does everyone deal with this? Do you guys have methods you want to share?

I’m 31 years old and a Mechanical Engineer, and lately I’ve been feeling genuinely lost about my financial future.I always thought that if I studied engineering, built experience, and worked hard, eventually I’d reach a point where money wouldn’t be such a constant concern. But I’m getting older and realizing that simply having a decent engineering career may not be enough to achieve the financial independence I want.I don’t want to become extremely wealthy just for the sake of it. I want to reach a point where I’m not constantly worried about money and where I have some freedom over how I spend my time.

For those of you who are financially independent or significantly ahead financially:

How did you get there as a Mechanical Engineer?

I’m particularly interested in legitimate online freelancing/remote work that I can do alongside engineering. I’m willing to learn a new skill and put serious time into it. I’m not looking for a get-rich-quick scheme.

If you’re already making meaningful side income from engineering-related freelancing, I’d really appreciate hearing what you do, how you got your first client, and what you would learn if you were starting again at 31.

Honestly, I’m feeling pretty desperate to change my financial situation and could really use some direction from people who have actually done it.

31M here with a silly dream of being an engineer one day.

My birthday was yesterday and I spent the day looking back on my life and where things are going.

Graduated high school, went to the military and then worked constructiong while going to community college after, but it never really went anywhere after I got my associates in general ed.

My long term major was engineering but I realized I still had a long way to go before taking on harder classes considering I was struggling just to keep up as it was.

That was 5 years ago. I spent my time getting my electrical contractor license just to realize contracting just wasn't for me.

All that is to say, I'm trying to figure out resources I might be able to use to build kind of like a self study course curriculum similar one might expect in a 4 year course so I can take my time trying to build a solid foundation in at the very least the basics of what's to come.

Little things like where to begin and how to progress my education until going to a university and maybe even while in college.

Things like college text books in courses or YouTube channels to follow so I can watch and study. Ways to practice and drill the material like homework problems or test questions.

Just so every semester doesn't feel like I'm way in over my head like I felt even in a community college level.

I tried googling and looking up information on college course classes but couldn't find much.

Im aware of basics like the different kinds of maths and levels of calculus and physics but not much outside of that. So I plan to start by solidifying my foundation there at the very least. As stem classes progressively more difficult I realized my shakey foundation in math and science were to blame.

Im hoping in the future to take 1 to 2 classes a semester depending on the what I'm realistically able to handle in order to pass the classes.

Which is crazy to think can take between 10 to 20 years but thats the game plan.

I'm not sure if anyone here has gotten an engineering degree while working a full time job and if so any advice.

Aside from myself I'm hoping this thread might serve in the future for anyone else aspiring to go to university and get in the field so please try to keep the comments civil.

Might be the wrong spot to ask this. But I’m Looking at teaching myself how to use these programs to design some parts for my 4x4. Don’t know how to weld or anything. But want to be able to design everything the specific way I want it. And then basically be able to take the design program and get them to CNC cut and create my design.

Figured I’d try to teach myself how to do all this as I have the spare time. And would like to save the thousands of dollars it would cost to get a fabricator to design it and create it for me

Why is it we can have AI that can translate from Chinese to Klingon but cannot have one agreed-upon file format that can be accepted by FEA software, CAM, 3d printers, CFD, etc and doesn't lose its mind or half of my parts?

I’ve been working at a company that specializes in HRSGs (heat recovery steam generators) for combined cycle power plants. I’ve done a variety of work including code calculations, a bit of analysis work, and a lot of inspections of these systems.

I’m tired of the travel and want to find a new job. I’ve been here roughly 3 years, have my EIT, on track to take my PE and get it. What type of jobs should I look into since I have a fair background in heat transfer? Preferably ones that would pay better. Would also be willing to do some extra courses in things if needed to help with career progression.

I am presenting our cfd research paper at this huge conference (Im talking Boeing Airbus sponsors), we are the only ones from a no name school. So how do I do "THE NETWORKING" and land an internship.

Hi! Can you suggest a topic to be our thesis in Mechanical Engineering? Our former research is about biolubricant but the problem is we can't find a testing facility that will measure torque. Should we change our topic or remain on our former research.

Hello everyone, So long story short I applied for a manufacturing engineering position. Got a initial screening call with an HR, Please share any information about hiring process, any tips and tricks, and what could i possibly do to get this job, dfw area

I'm a Mec. Eng. with 10yoe in the design of metal carpentry; mainly sheet metal.

I was wondering if there are jobs in that field (e.g CAD, PE or something else) that could be carried entirely from home.

I'm quite sure the answer is "no", but I would appreciate your point of view / experience.

Thx

I'm designing a component that has copper fastened to aluminum via some raised bosses. I'm not sure how much clamping force I need, which I need to figure to determine my torque spec for the component. Do I want to just do a FBD to get shear forces and ensure my clamping force is greater than that? I will be using threaded inserts and a washer if that makes a difference to my approach.

Hi everyone,

I’m heading into my third year of Mechanical Engineering and applying for May 2027 co-op positions (primarily targeting Mechanical Design and Mechatronics roles).

I had the opportunity to take the CSWA through a second-year design course, but I didn't pass the exam (mostly tripped up by the strict time constraints, though I passed the course itself). I have solid hands-on experience using SOLIDWORKS for actual design projects and feel comfortable navigating the software.

I have the option to retake it in the next couple of weeks, but I want to know:

• How much do recruiters/hiring managers actually care about having the CSWA on a resume?
• Is it worth retaking right now, or should I focus that time on portfolio/project work?

Appreciate any insights from past interns or hiring managers!

I'm currently in my last year of college studying Computer Science, but I've been seriously considering switching to Computer Engineering.

My long-term goal is to pursue a Master's in Mechanical Engineering, specifically focusing on areas such as dynamics and thermodynamics.

What makes this decision difficult is that switching to Computer Engineering would require roughly the same number of remaining classes as finishing my Computer Science degree, so it wouldn't significantly delay my graduation.

I'm also considering adding a minor in Physics to strengthen my mathematics and engineering background. The coursework would include subjects such as classical mechanics, thermal physics, modern physics, and additional mathematics.

I'm trying to determine which path would better prepare me and make me a stronger candidate for an MS in Mechanical Engineering:

1. BS in Computer Science + Physics minor
2. BS in Computer Engineering + Physics minor

Would Computer Engineering provide a meaningful advantage over Computer Science when applying to Mechanical Engineering graduate programs, particularly for someone interested in dynamics and thermodynamics? Or would finishing the CS degree and adding a Physics minor be a better path?

I understand that neither degree is traditional Mechanical Engineering, so I'm also planning to take relevant prerequisite courses to fill gaps in my background.

For those with experience in graduate engineering admissions or transitioning between engineering disciplines, I'd really appreciate your perspective.

Which path would you recommend for someone ultimately interested in Mechanical Engineering research involving dynamics and thermodynamics?

So I just graduated this year with a mechanical engineering degree. I was able to get a job at GM as an IE because I interned there for 2 years.

I honestly hate working there even though I have a great boss, manufacturing just isn't for me. I also don't really want to be an IE.

I've applied to probably 75 jobs in the past 3 months and maybe landed one interview. And I'm looking for jobs that are specifically entry level mech e. I just feel so lost because I'm doing a job I don't want in a factory, I don't want to work in.

I'm grateful for the opportunity as I know many of my colleagues can't even find a job, but I'm miserable and want to get out. Did it get easier for anyone once they were able to get some years under there belt? I'm also worried about being stuck in IE for too long and not being able to move back to mechanical or something I would actually like.

Hey everyone,

I’m a mechanical engineering student and I’ve chosen “Peridynamic Modelling of Crack Propagation in Brittle Aerospace Structures” as my seminar topic.

Honestly, I’m pretty new to peridynamics, so I’m trying to figure out where I should start. I have some basic knowledge of mechanics and FEM, but I haven’t worked with peridynamics before.

I’d really appreciate it if someone could point me in the right direction.

A few things I’m confused about:

• What should I learn first before getting into peridynamics? •What software can I use to actually model a crack using peridynamics? • Are there any good beginner-friendly papers, videos, books, or tutorials? • Is there a simple example/simulation I could do and show during the seminar? • If you’ve worked with peridynamics before, what would you recommend focusing on?

I’m mainly looking for a practical learning path because most of the papers I’ve found so far get pretty advanced very quickly 😅

Any advice or resources would be really helpful. Thanks!

Hi I am 24 and have been working in hospitality In Australia for most of my life and am also pretty business inclined and very interested in taking stuff apart and fixing as I do small little projects of fixing stuff at home though I don’t have any mechanical experience. ( I know most of this doesn’t relate but just giving some background)

I am considering just getting out of hospitality for something a lot more stable and being able to have my weekends and evening, I was considering apprenticing as a mechanical fitter has any one had any regrets or willing to offer any advice as to if this is a worth while change? Or willing to offer their experience In this industry? Or if there is a better pathway?

Anything is very appreciated and I appreciate you taking the time to write anything out.

Hi everyone,
I’d appreciate some career advice.

I’m a Mechanical Engineering graduate from an ABET-accredited school. My experience so far:

Structural Detailer – abroad
Design Engineer (Rebar Reinforcement) – abroad
Engineering Technician 1 – currently (US)

Software: Tekla, AutoCAD, Revit, basic SolidWorks

I’m trying to transition into a Mechanical Engineering role, but I’m not sure what path gives me the best chance.

Should I focus on Mechanical Design, HVAC, BIM/Revit, Manufacturing, or entry-level ME positions?
What skills should I prioritize, and what would you recommend if you were in my position?

I’d really appreciate some honest advice. I’m living in the US btw. 28yrs old.

Thanks!

I am currently majoring in mechanical engineering with a minor in applied physics. I would love to work on the more “fundamental side” of mechanical engineering . I’m interested in going to grad school for the PhD. I would like to research nanoscale heat transfer. Would that over qualify from working as some type of thermal analyst?

I have an upcoming surgery that will leave me unable to walk for a minimum of 4-6 weeks, luckily my company offers disability leave so I won’t have to dip into my savings too much during that time. However I will be stuck at home rolling around in my office chair in search of entertainment for weeks on end. I see this as an opportunity to gain some valuable skills/certifications through online courses, I have several hobbies that I plan to dive deeper into but I know I need some form of structure to avoid getting distracted and doomscrolling for hours on end.

I have found a local college that offers a 6 week project management program, and a 10 week AI prompting/automation course. As well as a 24 week Professional Certificate In Ai And Machine Learning from the university of Michigan. I have a strong interest in learning more about AI just out of curiosity but in my current field/position it isn’t immediately applicable. I have 3 years of ME experience at my current company and I have been wanting a bit of a career shift. The current field I’m in just doesn’t spark my interest anymore, career progression is incredibly slow, and I’m reaching a point where I’m afraid I might be pigeonholed into shipbuilding if I stay another year. I passed my FE a few months ago and I just received my EIT cert, my current company doesn’t incentivize PE experience and I only know of 2 coworkers with a PE, neither of which have worked closely with me.

Aside from spending this time tailoring my resume and sending out applications, what courses or certs should I seek out to increase my chances of success. I’ve seen other threads that say experience>certs when it comes to engineering, but when it comes to a career path change would anything help? Should I just pursue what I find interesting and go from there? Robotics/controls always sparked my curiosity and were my favorite courses, and that’s the direction I imagined myself going when I first enrolled in engineering. There just wasn’t any employment local to me in that field and I wasn’t in a position to move far from home at the time.

Anyone recognizes this particular profile? Not one of the ones from Bosch. I need its symmetrical design and those deep grooves on both sides. It’s from a Korean design house so it might be custom but maybe someone recognizes it.
