I have heard that digital Calipers are a must. If I want to make some cute little robot projects on the side for my portfolio, or things like a laser gun game that I can play on my tv screen, what are some tools and materials I definitely need to get? (already have a bambu p1s fdm printer)

Hi everyone! I have an upcoming live design challenge interview for an Apple Product Design Engineer role on the Data Center team. The recruiter mentioned that someone from the Mac PD team will conduct the interview.

For anyone who has gone through this round, what kind of design problems should I expect, and what would you recommend practicing beforehand?

Any advice or insights would be greatly appreciated. Thanks!

Hey guys, does anyone have experience with the second round space X interview for mechanicals, particularly the Test Engineer role? Any advice or insight into potential technical questions or what to expect is really really appreciated, thank you

People keep asking me to do masters or mtech , I spent so much in my mechanical bachlors and am still not placed , feels like money wasted how's mechanical carrier with and without masters experience? Does it really make a difference?

Is anyone out there for guidance and help share experience throughout my university time?

Recently, I joined as an entry level Engineer in a big power equipment manufacturing company. Work is related to fuel systems design for boilers which includes designing/modelling piping drawings in boiler floor for fuel oil and gas, procuring fuel systems components includes but not limited to strainers, butterfly valves, oil pumps, ignitors etc. No one is there to guide me properly but expecting me to work. I don't know what to do because I'm just new and everything is confusing to me like what to check and what are the key things i should consider before procuring or making specification for components, what things to consider for piping, forecast etc. I'm having ADHD and it makes my learning worse because i can't concentrate on a single thing and trying to learn more standards or docs simultaneously which leads to nowhere. Give some doable tips to work thiough this. I don't want any chatgpt answers and I want some from the people who had worked or have been working in similar roles.

anyone working in bearings or power transmission here? im trying to map out the industry platforms people actually check, not generic directories that happen to list bearings. Bearingnet comes up constantly, but surely theres other networks where distributors trade stock, find obsolete parts or connect with manufacturers. alibaba obviously has loads of bearing factories and thats useful on sourcing side, but im more interested in industry networking and inventory exchange here. does anything else have enough active companies to be worth paying attention to? maybe regional platforms in europe or asia? id rather have one smaller network where members actually respond than ten directories full of company pages nobody touched since 2018.

Hello guys, I just graduated as mechanical engineer from nepal and planning to go abroad, and till that time i want to do some job and explore here.

On which field should i go or take experience

I am so confused about which area should i explore and try.

please drop you feedback

Hi guys I'm a final year mechanical student who got placed in va tech wabag for 5 lpa, i didn't mean to get placed but I have good knowledge of pumps and also cleared gate in 5th sem which made the interviewer recruit me . But the problem is I'm more into heavy engineering like designing pressure vessels and stuff I tried to get into l and t, but unfortunately Our college has one time offer policy and I wasn't able to attend L and T or other companies. Can someone really help me get a job in heavy engineering industry like pressure vessel and heat exchanger design. As of now I'm doing ASME courses and I'm from tier 1 college in tamilnadu. Any salary around 40k is enough. Please do help me and if anyone can get me an interview I'd forever be in ur your debt. Thank you

printed housing for a handheld test instrument passed every functional check, so we sent the model out for prototype injection molding quotes. the feedback list is longer than the part. draft on every wall, wall thickness going from 1.2 to 3 mm in spots, 2 bosses that need coring out, and a snap that apparently cant be molded without a side action. which of these did you push back on and which did you just accept?

Hello Engineers,

Looking to connect with fellow Mechanical/Structural Engineers in Toronto.

Just want to do some networking and have contacts that would help each other. 💯✔️

Hey everyone,

Quick design question for the piping / pressure vessel engineers here working with ASME B31.3.

When doing quick sanity checks on required pipe wall thickness (t_{req}) for high-pressure lines, I’ve noticed a lot of variation in how different engineering teams handle c (corrosion/erosion allowance) and T_{mill} (mill tolerance, usually 12.5%) during early design stages.

Specifically:
1. Do you usually factor in the 12.5% mill undertolerance directly into the nominal thickness selection right away, or do you run the exact calculated t_m value through a standardized lookup routine first?

1. For temperature-dependent S (allowable stress) values, how often do you rely on quick digital lookup sheets vs manually cross-referencing Table A-1 in the code book when double-checking vendor design packages?

I've been scripting a lightweight internal lookup utility to automate these repetitive B31.3 / B16.5 checks for field/site reviews, but I want to make sure the calculation flow and output breakdown reflect standard industry practices.

Curious to hear how your teams streamline these code verification routines or if there are specific edge cases that usually cause headache in field checks.

(Happy to share the test script/tool privately via DM if anyone wants to look at the math logic, but mainly looking for design workflow thoughts here.)

Thanks!

Hey guys, I graduated with bachelors of mechanical engineering and the salaries im looking at currently at the market is subpar and wanted to know if anyone here did a masters in mechanical engineering and were able to secure a good position by doing so ?

We supply industrial equipment that has exhaust gas temperatures around 1400F. The duct handling this air has an internal water jacket, water flowing over a weir along the internal wall, that starts the cooling process and is used for scrubbing further down.

We have had issues with the water supply being insufficient or just turned off and the duct being held at excessive temperatures resulting in buckling, but at times welds failing. When this happens, my clients typically know what happened right away. But in the case of failed welds it inevitably results in some sort of investigation to show they turned the water down or off.

I was thinking of applying either decals or a temperature indicating paint to the duct when new so we could easily identify what temperatures the duct was exposed to. This would save me and my clients time by quickly identifying the duct was overheated.

Does anyone have experience using such decals or paints in an industrial application?

I was thinking something like Tempilaq Advanced Liquid Temperature Indicator (gets me up to 1500F if I would like) or MMC 5952K239.

I am more curious on how they hold up over time in harsh environments.

I’m in my senior year of mechanical engineering at UT Arlington. I expect to graduate in August 2027, although depending on how classes line up, perhaps December 2027.

I’m particularly interested in robotics, Mecatronics, electrical, aerospace, and overall, very technical work.

I have a 3.3 GPA and 1 engineering internship from 2 years ago (Summer 2024) but that was with TxDOT, so it was in the public sector.

I have about two semesters of undergraduate research from 2.5 years ago.

For projects and extracurriculars:
—I’m currently building my own L1 rocket through my schools rocketry club.
—I’m currently working on two class projects involving optimization, CFD and thermal analysis.
—I have a personal project that I’m currently working on which is a robotic arm I’m building from scratch.

Next semester I’ll be taking senior design and a mecatronics class which involve more projects.
I have quite a bit of experience with CAD and CAE.

My main concern is that I’ve mostly focused on academics for the past 2 years and not gaining industry experience or getting involved with organizations.

That said, how realistic is it for me to shoot for those specific industries? What should I prioritize the next 10 months/year to make myself competitive for those industries? Has anyone had a similar experience?

Hello everyone, I joined the group recently and, to be honest, I wanted to share with you a fear that’s been on my mind for the last three months. I’m currently in my second semester of mechanical engineering. To begin with, I chose this degree course because maths and physics were the subjects that interested me most at school and the ones I was best at, and the idea of inventing things using that knowledge really appealed to me – essentially, bringing something to life with my knowledge, like the YouTuber Mark Rober. however, throughout my short time on this journey, I’ve realised there are things I like and others that scare me. One of these – and the biggest one – is the complexity of the degree; I’ll be faced with some really tough challenges, and just thinking about that terrifies me, and also the thought of dealing with machines – especially heavy, highly complex machinery, such as industrial machinery or, I don’t know, a rocket or an aeroplane. The thought that at some point I’ll have to build such complex things all by myself terrifies me because of just how complicated it is. I’ve often thought about switching to industrial engineering, and I know it might sound funny, but it’s because there are far more girls on that course and it’s easier, not so much because it appeals to me – in general, across many degree programmes – because at this point I feel I’ve lost my focus. Any advice, or has anyone else been through the same thing?

Translated with DeepL.com (free version)

I want to start a career in engineering after school but I don’t have any hobbies that relate to it. I crochet and play the piano and that’s about it. I like the idea of being an engineer because I’ve always enjoyed maths and I like the idea of taking things apart and figuring out how they work.

what can I do that I can add to my CV and will be useful in interviews to show my interest in wanting to become an engineer

Hi everyone!

I'm currently pursuing a BSc in Mechanical Engineering in Bangladesh, and I'm trying to figure out which career path I should focus on before graduation.

Mechanical Engineering seems to offer opportunities in many different fields, but I'm not sure which ones are worth prioritizing as a student.

I'd love to hear from people who are studying Mechanical Engineering or already working in the industry.

A few things I'd like to know:

- Career options: Which fields can Mechanical Engineering graduates enter besides traditional design and manufacturing roles?

- In-demand skills: Which technical skills and software are actually useful for fresh graduates? (AutoCAD, SolidWorks, Excel, programming, etc.)

- Industries: What are the opportunities in manufacturing, HVAC, power and energy, maintenance, quality control, and renewable energy?

- Job preparation: What should a student focus on before graduation to become job-ready?

- Bangladesh vs. abroad: How do career opportunities differ for fresh graduates in Bangladesh and other countries?

I'm particularly interested in practical, industry-oriented careers rather than limiting myself to one specialization too early.

If you've studied Mechanical Engineering, hired fresh graduates, or worked in any of these fields, I'd really appreciate hearing about your experience.

What would you recommend to someone who wants to build a strong career in Mechanical Engineering starting from the student stage?

Thanks in advance!

I have a BS in Computer Engineering and I'm interested in moving into Mechanical Engineering, particularly thermal/fluids, propulsion, and aerospace/defense.

Would it make more sense to:

• Get a second BS in Mechanical Engineering, or
• Go straight into an MS in Mechanical Engineering and take whatever undergraduate ME prerequisites I'm missing?

Would BS CE + MS ME be viewed negatively by employers, or would the MS be enough? And would a second BS provide a significant advantage?

A Critical Installation Mistake with Conical Spring Mechanical Seals

Conical spring mechanical seals are widely used in pumps and industrial equipment. However, a small installation mistake can lead to serious operational problems.

What is the function of the conical spring?

The smallest inner diameter of the conical spring is designed to be smaller than the shaft diameter. This allows the spring to grip the shaft and transmit torque to the rotating seal assembly.

The critical installation mistake

Sometimes, inexperienced installers use pliers to expand the spring's inner diameter because the spring is difficult to fit onto the shaft.

This is a serious mistake.

When the spring is expanded, it can lose its grip on the shaft. As a result, torque transmission may be compromised, allowing the rotating seal assembly to slip on the shaft.

What can happen?

• Loss of proper torque transmission
• Slippage of the rotating assembly on the shaft
• Damage to the sealing faces
• Leakage and premature seal failure

How can this be prevented?

1. Never expand the spring with pliers.
2. Use a suitable lubricant only if recommended by the manufacturer.
3. Install the spring by rotating it onto the shaft in the appropriate direction, following the manufacturer's installation instructions.

A small installation mistake can cause a major mechanical seal failure.
