And to finish that brief tangent topic, that bridge has very pertinent history on why they don't want big ships near it! (A smaller bridge, city and port so the economic effects weren't nearly as widespread, but still a big deal for the locals at the time.)

MJCronin (Mechanical) How can I turn on ability to do a reply here in eng-tips ?
Looks like the priorities/objectives have been altered. They are currently using a cutting torch to clear the bridge away from the cargo ship, so smaller ships that can still use the shallower part of the channel, can resume operations.

This website is something like 30 years old and probably hasn't been updated. This is not Reddit. There is no reply feature.

Use the 'Quotes' tool in the toolbar that looks like a person with a cartoon quote bubble above the head.

Thanks for your input. I guess it's the ability to Quote another's post that I can't find. I've been off this site for over a year, and that quote option disappeared.

Can I quote you in an article?

In the interest of journalistic integrity of your organization, no you may not. I'm a no name on the internet. Why would you quote me? If you want to use that idea, go for it.

As for replying...the quotes call attention to what was said for the sake of context, but it's not a reply in the modern sense of internet discourse. A 'reply' uses an @ tag or sub-thread to tie the reply directly to the original statement and/or call attention to the person who made the comment by an email or a notification on the page (so they don't have to scroll through the entire thread). This forum has nothing like that to my knowledge.

thanks again John R. Baker,

Torch cutting the beams continues, north of the ship location. In the past I noticed they have used robotic cutting torches, with their base resting on a barge, and operated by remote workers in a lift bucket. This could be useful when the cutting is at the ship location.

In the interest of journalistic integrity of your organization, no you may not.

It seems like a reasonable request, and if it is non-sensical given the anonymity, it still reflects well on the requestor for being courteous where none is required.

Going to take action if the quote is published anyway?

 

[phamENG]

I do appreciate that they asked. But the fact that they would want to quote a random person whose credentials cannot be verified does not reflect that well.

Would I take action? Really? Why would anyone waste the time or resources to do that? I told them to use the idea - that's all it is.

A reminder that Elmo is not an engineer, has never designed or built a bridge, hasn’t invented anything and uses his apartheid wealth to buy up other peoples work and pass it off as his own.

I just want to push back on this a bit. Elon Musk has been at the helm of - and in the weeds making design decisions at - premiere engineering organizations that are moving the state of the art forward across several industries.

How is he not an engineer?

 

[3DDave]

He is a monied entrepreneur. Engineers perform calculations to make predictions of future performance. Entrepreneurs pay engineers and make demands for future performance. Rare is the combination of an individual successful at both. Making demands is a separate decision process from engineering.

I doubt that Musk can install a battery into a TV remote the right way around, much less contribute to designing a phased array antenna to interoperate with a satellite constellation.

I will push back a bit as well. It is one thing to point out EM's uninformed takes (this bridge for example or his cave submarine or even the highly improbable view that we will ever live on Mars). But he has a degree in physics and is also a programmer and a gamer so being all those things myself I can say that your ad hominen is just wrong and says more about your own bias. I mean I really wonder about your motivations and associations given that you are obviously experienced.

EM will be awarded an honorary degree in engineering if he hasn't already been for his direction of SpaceX, Tesla, and Starlink which not only persist today but dominate because of his personal involvement in day to day operations, vision, and probably design direction as well.

 

[3DDave]

Musk has a bachelor's degree in physics and economics, not engineering.

He does attract an interesting crowd, but the management of SpaceX is famous for taking measures to keep him away from the engineers.

 

[KevinK2]

How about your source?

A friend's cousin is an engineer working at SpaceX for Musk, and he has nothing but praise for his visionary boss whom he is frequently conversing with. To assume he knows nothing technical is just assumption.

Having been a board certified professional mechanical enginnering consultant for 35 year, this video clearly shows that no engineeering degree is necessary for this man. The hows & whys of the improvements of the Raptor thrust engines, stages 1-3, per his vision for improvement:

But his populating Mars vision/effort is a bust, imho.

My grandpa was a college dropout that worked as a QA engineer at Aerojet on the Minuteman 3 project. It's not so common today but in the past one could become an engineer without an engineering degree.

You still can and many do. Plenty of states would issue him (*Elon) a PE license if he bothered to apply.

 

[TugboatEng]

He did apply... He was a QA engineer for Aerojet's solid fuel rocket program. He got recruited out of college by Bechtel before he graduated.
