IME critical fasteners are either spec'ed as one-time use or having a max service-life based on a battery of accelerated durability tests including salt spray/bath/etc.
Visual inspection by itself isnt enough for accepting batches of new fasteners at a manufacturing plant, hopefully you're not...
Not at all. Trucks with a factory PTO have had PTO limiters since the 70s. The issue isnt lack of technology, its that they're commonly bypassed or not installed by upfitters and owners bc its not illegal to do so. Growing up on the farm, we never bypassed them on dumps to prevent damaging...
Typically excavators are overwidth, not height until you get up into the monster mining machines that require removing tracks and booms to haul separately. In some areas they'll have a single escort but not a pole car, and typically just flags and an oversized banner. Judging from the rail...
Its called outlaw trucking, bragged about by idiots until they get arrested. In the pic it doesnt appear that the boom is folded in and down as required for hauling. Its not uncommon for drivers moving equipment short distances to not fold them up completely or even chain them down, which I...
Not sure what the logic behind your analysis is, but you're redesigning a critical joint so should be completing both a BJA and working with a fastener supplier/lab for joint testing. Your inserts and fasteners need to be sized appropriately to balance clamp and bearing loads, and fastener...
Many gear trains have an idler gear on an adjustable/offset pivot, similar to an automotive belt tensioner or multispeed bicycle chain tensioner. Instead of applying constant spring tension, techs manually rotate the pivot to set mesh depth and tighten a few bolts to lock the mechanism...
False. Again, in the US:
1.If you're contracted for a specific project then IP ownership defaults to the customer. This has been upheld for everything from traditional engineering projects to software to literature.
2. If you're on a regular long-term/time-based contract then IP ownership...
Two of my previous employers owned AL printers. We used them as a cheaper alternative to buying prototype castings. The print quality was excellent so it may not have always been necessary, but I always treated them as a raw casting and had precision surfaces machined after the raw part was...
The OP's concerned about potential liability bc of potentially owning the plans/IP. The quoted post explains why they likely have little liability and earlier posts explained why they likely don't own IP.
There are certainly exceptions but suggesting basic IP and liability concepts are...
If you're chasing corporate clients, the best way "in" IME is simply to (voice) call the public contact number for local sites, ask for the purchasing dept, then ask for the appropriate commodity manager. They might not have work for you today, but a major part of their job is to identify...
I've 3d printed AL engine parts for automotive prototypes that were subject to high stresses on-track and offroad, everything from plumbing fittings and brackets to pulleys and never had a failure. I wouldnt trust them to the public for 300k miles but internally for a few thousand is no problem.
In the US we follow strict liability, whoever sells to the public owns the liability. Those companies can sue subs/suppliers but are generally limited to a refund of the original $$$ spent rather than damages. This forces companies to give due-diligence to hiring quality subs/suppliers rather...
Sure. Rollover slings/attachments normally hang from a spreader bar, which hang from the crane.

If that is the totality of your engineering QC process then you'd be guilty of gross negligence in most countries, as well as violating the ethical standards of engineering societies. Insurance policies generally dont cover errors and omissions caused by negligence, nor do customers knowingly...
Gaskets often have the same issue with over-compression. You need the correct amount of both pad compression and thread stretch. Increase surface area of the stack on the pad and/or decrease thread size. Its a standard BJA but the tolerance stack analysis becomes more critical with additional...
I haven't hired them directly, but many customers of a previous employer hired Jacobs to do the site/installation design (rather than us) for our O&G equipment, which included shorter (<50') lattice and guyed structures. I've worked with them around the world and they always seemed competent...
IP law doesnt consider industry, nor does it care if you're a professional or member of the public. It gives equal protection to homeowners' sketches and engineers' CAD, and with modern technology there often isnt much difference.
Regarding liability, regulators and courts do give members of...
That's true for those with regular, long-term employment. However, folks contracted/hired/commissioned for a specific project are "hired to invent" and retain no IP rights unless granted by the customer. Our legal system also doesnt recognize IP claims that violate another's rights, and...
