JWST is already launched and in space. The only cancellation threat was in 2011 during the Obama administration.
Musk did suggest de-orbiting the USA though that is not his call to make.
Can you give an example of some pretty advanced space technology that is being terminated? Less phallic appearing rockets to appease the gender neutral crowd?
I guess the question here is, are you using 8.8 because it's commercially available or because you need the high strength?
In the USA to buy small quantities of fasteners (from a hardware store for example) its cheaper to buy grade 5 due to the higher demand vs grade 2.
What about the bushings? Shafts and bushings need to be selected as a pair. Nitronic steels make really nice bushings for poorly lubricated joints.
As an end user I don't see much difference in pin prices between 1020 steel (why are we even talking about 1020? 1040 doesn't cost more) or 17-4...
Are you testing for pressure drop over time or pressure drop from flow? Pressure drop over time indicates leakage which helium is commonly used to test for. Is this your case? If so, nitrogen is not a substitute.
Musk is a manager, not an inventor. We get it.
Consider Eugene W Kettering, son of a famous inventor. He worked as an engineering manager for various General Motors divisions and is probably one of most influential managers in history. He didn't invent the 2-cycle diesel engine but in the...
I think you've missed the point that the USA is funding many foreign projects. For example, DOGE is looking into $400M that the USA is sending to Australia universities.
No. The ships are faster than the tugs and when speeds exceed 6 knots the tug is using most of its power to traverse through the water and has little left to do any maneuvering of the ship. Certain designs of tugs with large skegs can exert very high braking forces at higher speeds but these...
How many of these projects were funded by the US government? Here is another collapsing. It seems that there has been a massive collapse of the global green energy initiatives once DOGE started looking under the covers...
Ford used the left hand thread on one side of their trucks and vans for quite some time. I think this is a good example of an engineer making a bad decision, getting it elevated to production, and the inertia of such a large organization making the bad decision impossible to fix.
Tankers already require escorts when loaded. A single tug is used. The tug only expected to act as brakes or a rudder. The key is the speed limit. Tugs aren't effective above 6 knots. If we impose escort conditions on container ships they won't have so much energy, either.
Plenty of ships hit bridges without any terrorism. The Bay Bridge has already been hardened against collision after 9/11 but ships are 2-3x the size today vs 2001 and it's simply becoming impossible to protect bridges from so much energy.
A real solution is to require ships over a certain size...
If the compressor turns clockwise, the reaction is counterclockwise, hence the left hand thread causes the compressor to tighten itself onto the shaft.
Left hand thread can be beneficial for connections that rotate in one direction around a single bolt or nut.
No, the shrinkage gap would be too thin to push epoxy through reliably. Use epoxies that are 100% solids to minimize shrinkage. You're also relying on a secondary bond between the epoxy layers that may not be as strong as the epoxy to steel bond.
As an off-road motorcycle rider, one of my favorite advices was, if in doubt throttle out. Whatever bad situation you're in, a handful of throttle and some acceleration is likely the best solution. This applies to all situations where your front wheel isn't already elevated.
Maybe that's the...
8.8 is a high strength faster, common stainless fasteners will not be a drop in replacement. A2-70 is common but does not achieve newr the strength of an 8.8 fastener. A2-80 or A4-80 are better but are still not the same strength. Proprietary fasteners such as Bumax 88 do get you into the same...
Maybe the danger is that if the joint separates during an operation you're going to lose the stock.
As for some off your questions, even if it isn't perfectly true, a little radial run out isn't going to have much effect on a flexible shaft that is primarily positioning axially.
Most lathes...
