I hang out on reddit subs for things like mechanical engineering, CAD, FEA, electronics and PCB design. It's not uncommon for people to be asking for help with their software (solidworks, fusion, abaqus, kicad, altium, etc) and posting

I bought christmas mini LED string lights last year from home depot, specifically labeled for outdoor use. Took them out this holiday season, and over half of the strings didn't work anymore. They have replaceable "bulbs", bu

I use Trello with Kanban style columns: to-do (sort of my backlog), pending (waiting on someone else or other external factor), in progress and done. I try to keep to cards in some order of priority.

Someone needs to haul big hunks of steel into the machine, clamo them down tight (and straight), and haul the part out when it's done. Also install tooling, swear when a tap or drill inevitably breaks and gets stuck in a very expensive

It's extremely common to use bitfields though. As mentioned by the article, it is recommended by ARM's CMSIS and thus found in vendor libraries of all cortex MCUs I have seen. arm-none-eabi-gcc changing its behavior for bitfields

Powerquery is a much more powerful alternative to pivot tables in modern excel. For one thing, you can chain queries, SQL style. IE, you can use the table that is the result of a query as input to another query.

Mechanical engineer in Canada here, I took a research assistant job in academia (after a few years in industry) to get similar benefits. 35h hours weeks, 5 weeks vacation, lots of flexibility for kid sickness (has been a godsend for the pas

That's a PhD (in engineering). Non-phd doctorates I'm aware of would be MD, Psy. D, JD.

Yes, our lecturer referred to it ass the bible, as he had actually taken Heywood's clas on ICEs MIT! It's definitely a huge brick though, can be intimidating. I think he picked the Ferguson book because it's more approachable

Shigley's Mechanical Engineering Design and Machinery's Handbook are two classic texts on the design of various mechanical components. For ICEs we used Ferguson and Kirkpatrick when I took a graduate level ICE class. It's con

Generally this process would be called linearization. You can create a complex, nonlinear, numerical model of the full system in as much detail as you want (eg implemented in a block sim like Simulink, or MBD software like ADAMS, or just A

The book we used in undergrad (mech eng) was "Manufacturing Processes for Engineering Materials" by Kalpakjian and Schmid. Not convinced it's the best, as I didn't really enjoy the class, but that was mostly due to a poo

Buying stuff is not a universal recipe for happiness. Neither is retirement, obviously, but you are correct that being financially independent gives you the freedom do do what you want. Whether that is time off between jobs, working on inde

I used to want to retire early and ASAP, firmly in the "lean fire" category. Then I found a job which pays significantly under market but that I actually enjoy doing. My priorities have changed a lot. Unfortunately said job is hig

Anecdotally, I've been using loctite C5A (copper anti-seize) on lug nuts for years without an issue. I also torque them to the manufacturer spec with a torque wrench twice a year (when I switch summer/winter tires).

Unless I'm misunderstanding the diagram, it does not look like fatigue at all but rather yielding from shear loading. The definition of fatigue is a small crack (in fact microscopic in the beginning) that grows through the application

When I worked on railway vehicles (bogies for passengers vehicles, more accurately), Nord locks (or equivalent clones) were standard on all structural joints. Especially on a prototype I'd recommend them. Prototypes are really expensiv

Adding on to that, tensioning bolts using torque is convenient and inexpensive but not very accurate at all. Some data reproduced in Shigley's Mechanical Engineering Design showed a +/- 30% variation in tension for properly torque

From my experience, laser cutting shops (we're talking about steel plate cutting right?) are annoyed with everything except DXF.

I'd recommend it. The syntax should make you feel at home if know python, though the type system (and std lib) does make it feel like a very different language once you use actually use it. One advantage over C++ is that you don't

For what it's worth, I'm not a (professionnal) programmer, and I can usually solve 80% of the AoC problems intuitively. That's OK for me. For the other 20% where I don't even know where to start, I look up a solution on

Matlab is awful at being a general-purpose language, anything that isn't wrangling matrices. Strings, paths, networking, etc are all really painful compared to Python or Julia.
