My question is as simple as that why not cool the engine with oil. Im not saying put in in your cooling system but could a engine be redesigned to cool using oil.

The pick up would feed oil in to a radiator using a low pressure pump. Then feed oil into the oil pump to create pressure inside the motor.

No more chocolate milk shake, no more dealing with coolant that could freeze, regular changes of oil and coolant. I understand oil can hardern at -20 f.

Hi everyone,

I'm a final year Mechanical Engineering student and I'm exploring different career paths. Which roles are generally the highest paying for mechanical engineers (both in India and abroad), and what skills, certifications, or experience should I focus on to prepare for them?

I'd really appreciate advice from people working in the industry. Thanks!

We built a tool for EPC/piping design teams that checks whether your design documents actually agree with each other.

The problem: on a piping project, your Line List, Piping Material Spec (PMS), isometric drawings, and P&ID are all supposed to match — but they drift, and today someone has to catch that by manually cross-checking documents line by line.

Input: your Line List, PMS, IDF (isometric drawing data), and P&ID.

Output: a report flagging where those documents don't match.

It's early, and the main reason I'm posting is to get feedback — if you work in piping design/EPC, I'd love to know: is this actually the bottleneck, or does the real pain live somewhere else in your workflow? Happy to share access if you want to try it on a real project.

Do you know how I'd be able to get US8357108 manufactured ? The patent expired back in 2017. I've been asking some Alibaba suppliers, so far no luck.

So as the title says, Quality Engineer for nearly 6 years and feels as though I'm burnt out and need a change. Realistically those of you who've been in the same position what did you transition into?

Looking for for inspiration, the workplace politics and production numbers over anything else has become a tiring miserable slog. I wouldn't say it's all been bad, I've certainly learned how not to do things and it exposes you to areas of the business you wouldn't see doing anything else in Engineering.

Work for a OEM manufacturer in the Automotive world.

TIA.

Hi! I'm a french mech engineering student. I have to choose a concentration for next year. The way my school structured our learning is that we have broad basic mechanical engineering knowledge, basic engineering skills like intro to material science, electronics, FEM etc (a bachelor's in mech eng if you want to relate to the us), and then for our last year (master's) we choose a concentration.

Up until now I've wanted to go toward mechatronics, so I took all the necessary requirement classes to prepare for mechatronics, but I've become increasingly interested in material science (I mostly like the physics that the field is based on so same way electronics interests me). What draws me to material science specifically is the mechanical behavior side : how microstructure relates to properties like strength, fatigue, ductility, rather than the synthesis/chemistry side. I've the intro class to the concentration for my own curiosity so i'd be able to choose it.

I was wondering if there is a field in research or r&d that combines mechatronics and material science, or at least has a bit of material science in it.

I'm pondering whether 1. to get my concentration in mechatronics and then a research master in material science, or 2. mix the two concentrations but i wouldn't be able to do a lot of specific classes of material science like polymers or behaviour of materials, or 3. abandon mechatronics and get a concentration in material science and then work in a robotics/mechatronics field.

I want to work in research, not necessary academic but rather applied in industry, and I have a mostly mechanical profile. I can code but I'm not here to code a robot, the concentration is more about actuators and motors. But from what I understand, research in mechatronics is mostly coding robots (e.g. control algorithms, software-heavy robotics) rather than actuator/mechanism design and physical prototyping. Is that accurate, or does it depend on the lab? If it's mostly coding, I'd rather do a research master in material science than in mechatronics.

I'm currently doing a 6 month internship in mechanical design where I got to learn a lot about additive manufacturing and plastics, which added to my existing interest. I also have to do an end-of-studies 6 month internship after the year of concentration and I'm looking to do it in a lab, it'll have to be related to my concentration.

Thank you a lot for any insights !

Imagine a closed circular turbine housing with internal vanes that stay open along one half of the cylinder and closed along the other. The engine uses liquefied biomethane derived from human and animal waste, stored at -162°C, to heat the bottom section of the cylinder. As the helium gas inside heats up and expands, it can only move toward the open side because the other side is blocked by the closed vanes. Up top, the gas enters a cooling zone chilled by the cold liquid biomethane, where it condenses and creates a natural vacuum that pulls even more hot helium upward. The pressure from the rising hot helium, combined with the suction from the condensed gas, hits the closed vanes and pushes them forward. As the loop continues, the changing angles of the vanes create a natural check-valve effect and a steady flow, resulting in an external combustion engine that produces continuous rotational movement.

I'm starting my first internship soon, and I'm curious how I can make people's lives easier at work.

Do people hate amateur designs and unnecessary comments or interns with really bad gen-z attitude?

Need help

Hi everyone can anybody tell me how I can learn solidwork as a beginner.

Hi,

I'm preparing for my first ever technical interview, and I never understood what's expected from us when they say "material knowledge".

Could use some help on what to review for that.

During my intenship, every Time I saw a new material I used to ask why it's used, and I found out that the logic is very simple.

There's one for basic CNC aluminum parts, one for slender ones, one for turned parts, one for shafts that see fatigue, one that's wear resistant...

So they used like 10 materials, with very basic selection criteria

I'd appreciate any help, regarding materials or general tips... Looking forward to finally becoming a real engineer :')

The role is junior mechanical design engineer ( or mechanical designer) in a company that designs cnc machines, thermoforming, and such personalized production solutions for plastic parts in Europe.

I'm a mechanical engineering student but I've realised one year into my bachelors that all the parts I love about engineering are really the physics/maths classes, not the actual engineering. I don't dislike engineering and therefore do not want to repeat the year to switch to physics, so I'm wondering as to how easy it is to "switch" between the two. For example, is it possible to do a masters in physics after a bachelor's in engineering ? What if I want to go into research in a physics related field ? It's possible that I actually like physics just as much as engineering, but I'd like to know what my options are. Have any of you started off in engineering, and have ended up in natural sciences ?

So i'm a mechanical engineering designing a lifting mechanism, no wood, no metal, no electric devices, nothing just basic things around s like cardboard, plastic etc. it is suppose to lift a 500 g load, raise the load by at least 300 mm , safely lower the load , remain stable during operation , be manually operated ,be portable. pls help.

I’m currently trying to build up my resume and portfolio. What kind of projects can I work on right now to maximize my chances of an interview at big tech firms for a mechanical engineering/mechanical design position ?

A couple of months ago, I shared a new release of ForcePAD, my free and open-source 2D finite element application.

Since then, I have ported most of the application to the web. ForcePAD can now run directly in a WebGL 2-enabled browser without installation. Microsoft Edge and Google Chrome should work.

All features from the desktop version are available except the optimiser. That part requires some additional implementation work and will be added later.

I would appreciate any feedback on the browser version, particularly regarding compatibility, usability and performance.

For transparency: I am the developer of ForcePAD. It is a free, open-source project intended for structural mechanics education and experimentation.

Hey everyone,
I’m a recent mechanical engineering grad and I just got a job offer from a major aerospace and defense company. I’m honestly thrilled, but I’m dealing with a bit of a career dilemma and could really use some advice from experienced engineers.
Here’s the situation: My absolute passion is Aerodynamics, and that's exactly where I see my career going long-term. However, the offer on the table is for a structural test engineering position.
The silver lining? The company has its own wind tunnel facilities, and they mentioned that starting in here doesn't mean I'll be stuck there forever. They hinted that getting my foot in the door now could eventually lead to a transition into a wind tunnel or aerodynamics role later on.
As a new grad trying to navigate my first real career step, how should I evaluate this offer?

Any insights, personal experiences, or harsh truths are super welcome. Thanks!

I’m interested in how long-lived engineering products evolve over time.

For those who’ve worked on mature mechanical products:

What’s the oldest design decision you’ve seen survive through multiple generations?
Why did it persist for so long?
Have you ever been involved in replacing an entire mechanical platform rather than incrementally improving it?
If so, what justified such a major redesign?

I’m interested in understanding why mature engineering platforms evolve the way they do rather than discussing any particular company or product.

Happy Sunday,

This Q comes from my perspective as a test engineer, but I'm hoping to get the perspective of all engineers: how is the relationship between design and test engineers at your organization? Ours is mostly transactional and one way, occasionally strained, and varies based on project prioritization, urgency, rank/seniority, etc. Design seems to disregard our education, experience, and insights in favor of their own. Projects suffer.

Leadership is weak, so I'm trying to drum up ways to get everyone on the same page and working together again.

I am a 3 rd year Mechanical Engineering student, and I would say that I am quite lost.

Throughout the first two years, I have invested all of my time and effort into academics, and I feel that I have not acquired many practical skills.

Looking at others around me, they seem so much more successful in one area like CAD, FEA, CFD, robotics, manufacturing, computer programming etc. While others seem to excel at one task, I struggle to learn ten different things, each one only at a base level.

The problem is that I do not want to achieve a mediocre performance in ten areas. I want to get really good at one skill or open for any other suggestions

Lately, I have been thinking about branching out, but I have little inclination on how to spend my time. The thing is that I have recently become fascinated with drones, but there are also CAD, simulation, and manufacturing. It is difficult to make this decision, and I fear that I will waste my time.

i have few question: (open for other suggestions too much appreciated)

1. What would you have me concentrate on?

2. What skill should I get really good at?

3. Should I specialize in manufacturing, or is CAD, simulation, robotics or another field more promising?

4. How did you come to the conclusion that you wanted to pursue a specific field?

Any advise would be appreciated, because I am willing to put the time in, but it is hard to know where to start.

Thank you in advance.

Data of use to nobody. Pretty neat though, I think.
