Is there any mechanical engineers? What you would wish to know when you were starting learning? What skills and topics you consider the most useful in mechanical engineering?

What is the fastest way to learn mechanical engineering in the nowadays when 3d printers are avaliable to be able to design and make custom clocks, engines, generators?

Just build a replacement nuclear power plant and reuse the water. Right?

I can't stand the SpaceMouse Pro. They ruined it! Why would they swap the nice tactile buttons for stupid gummy membrane buttons? And why coat the whole thing in nasty soft touch coating that is going to turn to goo? We peaked with the previous generation of space balls.

Since I've been working from home though, it has gotten quite annoying to unplug my SpaceExplorer and take it back and forth to the office. It would be so nice to have one of those fancy new wireless ones. But that's not happening, since they ruined it.

So, I added USB-C to mine, instead. Now, I'll just have a cable at the office, and a cable at home and just take the unit itself back and forth. I can even leave a USB-C to USB-C cord in my case, in case I need to use it with my laptop away from my docks! If anyone is interested, I can share the STL for the little breakout board mounting piece I made.

A University of Virginia professor believes he has discovered how to create a freeze-ray device, inspired by the Batman villain, Mr. Freeze. Rather than being a weapon, this device is intended to cool down electronics within spacecraft and high-altitude jets.

A tiny, hard-working bacterium -- which weighs one-trillionth of a gram -- may soon have a large influence on processing rare earth elements in an eco-friendly way.

"Traditional thermochemical methods for separating lanthanides are environmentally horrible," said Buz Barstow, assistant professor of biological and environmental engineering at Cornell, the corresponding author. "It's difficult to refine these elements. That's why we send rare earth elements offshore -- generally to China -- to process them."

Not sure how useful it is yet, but it sounds like with some AI and proper cameras you could use it to completely repair certain components. Theres something similar to this using electrochemical plating to repair microfractures throughout a component - only downside is that it takes like weeks to do it properly (I'll see if I can dig up the paper later)

Looking for some ideas for friends and coworkers. If anyone can think of anything cool, I'd love to see it.

The proposed fuel is not SAF, it's a combination of magnesium and hydrogen mixed with hydrocarbon fuel. It's estimated to give 8% more range over other existing aviation fuels.

Engineering memes was a favorite on a similar site that I used to use, wondering if this community would want some too

Tesla is facing issues with the bare metal construction of the Cybertruck, which Elon Musk warned was as tricky to do as making Lego bricks

Why is it so difficult to find a good source for this information? I can find half a dozen research papers but no real good centralized source for these things.

Hello everyone!

I'm looking for suggestions in how we can grow and develop this community. We have a chance to develop something interesting and the impetus of this change will rely upon all of us to make it happen. Are there any ideas that you'd like to see implemented here? Community events? Challenges? Support?

I'd love to see this place flourish, and anything that I can do to draw interest would be fantastic.

Thanks for your suggestions!

I understand that this could be rather controversial, but I feel like AI is coming whether we wanted to or not. I know some companies have already started taking steps towards AI and automation in general, others are avoiding it until it becomes more robust.

How have you or your company integrated AI into your workflow so far?

Do you believe that you've benefited from the use of AI at your workplace, or do you feel like it's introducing more problems than it's solving?

The coolest page on the net I know of for mechanisms. What's your favourite in here?

The goal was to time how long it took you to generate the model on your first attempt. It relied on user honesty as you don't really win anything, but atleast you could see how you stacked up against other CAD users.

You can confirm if you have the right design by checking the Volume of your component after you feel that you've "completed" the design.

I've done this one before. It's very fun.

If your interesting in trying it out, post your time below. I'm curious to see how you guys do. I'll post my time on Monday.
