Trying to make a DRW of a metric gear. Does anyone know the equivalent document for gear drawing standards Y14.7.1 in ISO?

Bayer MaterialScience used to have a trove of design guides for injection molding in addition to other resources. Does anyone happen to have them archived and are willing to share?

Seeking advice on a workstation for handling complex CAD designs and FEA simulations. Any recommendations within a budget of £2500? What key laptop specs should I prioritize for these tasks? Thanks in advance!

I have an interview coming up next week that's going to be for a position on mechanical + business. It requires knowing mechanical engineering fundamentals. I did my bachelors and masters in mechanical but been a few years since I graduated and have been mostly in business related roles. Any tips/recommendations on the best way to brush up on meche concepts? I checked out MERM but it's over 1400 pages, seems like overkill studying that in a week?

I'll be starting grad school in about 4 months and looking for tips to prepare. I'll be doing a M.S. Thesis with my focus/research on robotics and controls.

First, what general tips do you have for grad school? And generally what subjects would you recommend to brush up on?

Second, what specifically would you study to help prep for these classes?... My first semester I'll be taking a course on Classical Control Systems which will cover frequency, time, and sampled data domains. And a course on Robotics 1: Mechanics, which covers mechanics of robots, comprising kinematics, dynamics, and trajectories.

I am a Senior Equipment Maintenance Engineer looking to transition into Mechanical Engineering roles. I am open to Engineering Technician roles and eventually move up to Mechanical Engineering roles. I have a B.S in mechanical engineering. I am currently looking for roles in SoCal.

I have applied to a lot of roles, but I cannot get to the interview stage. I am thinking my resume is not communicating my skills effectively. What can I do to transition into Mechanical Engineering roles? Any advice would be appreciated.

Help! It's OJT season na, and I still don't have company na papasukan, emailed LOTS of them pero wala nagrereply, if meron man, hindi pasok sa requirements ng school which is sobrang maarte ung school namin.

Any tips and recommendations po sana huhu😭

Hi, I am looking for freelance opportunities in CAD. I am proficient in PTC Creo and Soldiworks. Any help with finding the opportunity is appreciated.

I am an mechatronics engineering student and would like to ask your opinion on a list of materials that is common and cheap and useful for most applications that is a must know in the field of machine design

I'm graduating soon from RIT with an MET degree, and I've been told two things: 1. that I'm capable of getting an ME position, that is an engineering labeled position rather than technician, and 2. by a friend was told that accepting a technician position prevents you from getting regular ME jobs down the line as places will consider you only hands on labor and not to do calculation and FMEA type work for design reviews and such.

I really eventually want to work in a place that is like the latter where I'm using the bulk of my knowledge at my job, instead of just being a drafter. Will accepting this type of position handicap me?

Does anyone have experience with this?

I do a lot of concept drafting and much prefer using ink and white out vs pen and eraser.

I'm looking for a drafting compass that uses ink.

Any recommendations?

I'm about to complete my first year in mechanical engineering (with a specialization in manufacturing). What important softwares should I start learning? (Keeping in mind future job requirements and industry trends.) Also, which of those should I start with first?

(PS: I have learnt the basics of Solidworks/Matlab/Python/Java)

Personally I think nuclear is the future. SMR's are cool because of the scalability and the ability to fabricate major components of the nuclear steam supply system (NSSS) in a factory environment and then transport them to the site it allows for a less centralized grid. Gas is great too but still a fossil fuel. We simply can't just keep burning coal and oil to power and heat industry.

Thoughts?

Hi all,

I'm looking to source some very small drive wheels like these:

https://www.meridianlab.com/products/ml6-stock-sizesdrive-rollers/

I need a rubber outer diameter of 8mm and a width of 4-5mm. Ideally the bore would be a metal press fit. Mccmaster have some bits but they are too big, same with Misumi. I only want to buy around 10 ideally in Europe. Does anyone know where I could get something like this? 3D printing could also be an option I need the rubber part to have good friction. Thanks!

Not sure if this is the place to ask this. I'm not in the mechanical engineering field, but taking a fire fighter exam that has a mechanical aptitude section. This was on a practice quiz. Reddit seems to be the place to find people who know stuff.

Is the reason that it's not one belt due to a belt not being able to slide on top of another belt (at wheel A)? Though, if it's two belts, it seems like they would then have to be narrow enough to run side by side (on wheel A)?

Trying to train myself on how to think about these various topics. The prep courses seem to be written by unvalidated courses and non-experts with people pointing out errors in the comments.

My boyfriend is graduating with his masters in mechanical engineering and I’m not sure what to get him. Something personal but still useful. He did his research project on an underwater wind turbine if that tells you anything. He’s into legos and 3D printing but he also loves to cook and go camping. I was thinking maybe a nice portfolio or mechanical pencil? I’m not sure though, any help is appreciated!

Can anybody share their experience working for airbus. What’s the average total comp for entry level engineers to have met or communicated with?

I’m currently in High School now and I’ve always liked how things work, specifically on cars like the drivelines, engines, suspension. My doubt comes from my scores on the ACT being a 24 composite with 24 science, 28 reading being my highest but math being a 17. It’s weird because I like math, I have a want to learn and it doesn’t seem boring (most of the time). It’s just the fact that even though I can succeed in a classroom with my combined GPA being a 3.95, I struggle with the end-of-year tests for math like the ACT. Ive been seriously looking at committing to Northern Arizona University and/or Arizona State University since I’ve heard good things about their ME programs. However the scores are super concerning since I can’t afford to commit to the degree if i genuinely don’t have a chance in completing it.

Hey guys,

I 23M, graduated with a BS in mechanical engineering last year. I landed my first job in the renewable energy sector and took it without looking back, specifically as a PV design engineer. It's been a year now, and I spend most of my time doing layouts using AutoCAD, which isn't exactly in line with my mechanical engineering background. Now, with some savings and experience under my belt, I'm considering switching to a job in the mechanical industry. However, it's been tough finding opportunities without direct experience in that field. How challenging do you think it would be to break into the mechanical industry without prior experience?

On another note, I'm also wondering whether it would be worth it to stick with the solar industry, given its growth trajectory. I'm open to staying in PV if the pay is good in the long run, I'm aiming to make at least $100k mark over the next 1-3 years. Which industry would be the best to look into if I wanted make a switch from solar?

Any thoughts or advice would be greatly appreciated!

I (26M) am currently a Mechanical Design Engineer (1yr of experience) at a small aerospace company but always wanted to learn/work in the automotive industry.

Background: Graduated with a B.S. in Mechanical Engineering/ B.S. in General Science.

Recently I came to the conclusion that I kind of dislike my job. The work is fairly easy, my coworkers (excluding management) are nice, but I hate just sitting at my desk and staring at a computer all day. I love building/tinkering with and working with cars, always have. Aircrafts are okay but don’t drive my passion and motivation like automobiles do. I’ve been thinking of making the switch after getting 2-3 years of experience being that I’m a somewhat recent grad but rn even 2 years seems like a stretch now. (If it sounds like I’m complaining for no reason I understand)

If I switch from Aerospace to Automotive, will the experience hinder my ability to get a job at an automotive company? What are some things that I should take in consideration given that the industries are completely different?

My son is only two but he’s hit all his milestones very early and is essentially almost at the same level as my 4 year old in every area (except emotions). He seems to gravitate towards working things like fans (oh boy does he fucking love fans), electricity (turning the lights on and off and astonished by the dimmer), playing with the washing machine and dryer and figuring out how to make it spin, and airplanes/sirens, not to mention he can navigate the iPad better than his 4 year old sister, but that may be every child nowadays?

I feel like I’d be doing him a disservice if I didn’t expose him to a kid friendly mechanical engineering app/toy/project/game. Anyone have some suggestions?

Graduated with a finance degree which I never used because I decided to be a pro-athlete. After injuries forcing me to choose a different career path, no financial firm wanted to hire me. So I decided to learn additive manufacturing on my own, which came easy to me, and I eventually built my own 3d printer, learning tons along the way (specific to 3d printers) . Now I am in a manager position at a company for additive but I feel like I hit a plateau due to my gaps in engineering knowledge...

Could anyone in the community be kind enough to share a path on what to study on my own in particular order and resources where I can find reputable guides/lectures? Reputable certifications worth chasing too if any. I am 100% committed to the additive industry and this feeling of stagnation has been a splinter driving my anxiety. Thank you

I have this sheet metal part that is welded to an angle as sketched. It is a circumferential fillet weld. How do I calculate the stresses in the weld?

I have given the force, the angle of force and the weld thickness. The stresses are made up of shear stresses an tensile stresses of course. So I think I need to determine these and then calculate equivalent tension using the maximum distortion energy criterion.

It is difficult to calculate the individual shear stresses and tensile stresses in this case isn't it? Or am I overcomplicating things? Would you just divide force by overall weld area and be done?

Hoping some folks here have a bit more design experience than I do with gas strut lift systems.

Basic question is will this work? This is the roof for a camper shell, upwards motion will be started by hand then strut assisted.

https://imgur.com/a/qEu1vrD

Load being lifted is 200# and I was hoping to use 4x 80-100lb gas struts to lift the load (the two pictured and two more at the far end in the same orientation). Is there a better place to locate the strut attachment points to allow this sort of movement? Is there any benefit in a 20" strut vs a shorter or longer strut?

I have been fortunate to have opportunities in ME where I have grown and learned at a very rapid pace. I became a Sr. Mechanical Design Engineer at 26, an Engineering Manager by 28, and finally a Director/Sr. Manager of Engineering by 31. This progression was possible by moving between companies and again I understand that I am very fortunate in my career to have had this. I was able to take advantage of specific opportunities by taking a lower title role and then proving my worth once in the door.

However, I have recently left my job at a startup (Director/Sr. Manager title) and now am afraid that going back down to Sr. ME, or any individual contributor role for that matter, is going to look poorly on my resume and be a red flag for recruiters. Am I overthinking this or have I reached the point of no return and need to continue inline or forward in title?

I'm finishing my sophomore year of Mechanical Engineering. I am thinking about transferring into Ocean Engineering. But it would be to a different school. So my consideration is to either go to A&M for Ocean engineering or continue my Mechanical engineering at my much smaller but still ABET accredited school. I have an internship lined up with an oilfield service company and will likely work in the oil field when I graduate school. So l am wondering if what l consider to be a lesser degree from a bigger school will be better than a stronger degree from a smaller school.

I'm a 4th year mechanical engineering student.

I want to buy a new laptop, I used to have to have a MacBook but it doesn't work anymore, initially I thought about buying the new MacBook but after I saw that the application iam using this year, solid works and CFD analysis(starccm+ or ansys) which I can't download on Mac unless I download I version of windows using bootcamps or parallels.

so I thought about switching and buying a window laptop instead and was recommended to buy the xps 15 or hp victus 15.

what do you think should I get a new Mac and download windows or get a windows laptop instead, take into consideration that I already have a full apple setup(iPhone iPad ...).

if you think I should a windows pc, which do you recommend or what specs?

thank you.

Pretty much the title. Adruino projects are great for playing with a microcontroller, doing some wiring, and making something functional and fun. Is there an ME equivalent?

I was thinking about the problem of designing a holder that would be able to consistently apply pressure across the surface for preventing itself from falling by slipping.
My quesiton is, how do you design such that when you tighten the screw the pressure is distributed evenly across the entire surface, instead of it decreasing as it gets farther and farther away from the screw?
My answer by intuition was to slope the surface, aka making it closer in the top part and farther in the bottom part such that when the screw gets tightened the pressure should be somewhat evenly distributed, although I would think that it wouldn't be very easy to know how much to slope the surface to achieve an even distribution of the force.
