I play heavily CPU bounded games like Cities Skylines which should in theory benefit from the 9950's additional cores, but I'm wondering if this is true due to the V-cache allocation. Would I see near identical performance to a 9800x3D even in such CPU heavy and multi-core capable games?
I'm in process with two teams for software engineering right now, one of them scheduled my on-site panel today and I'm waiting for the other team as well. I know Apple only gives one offer from one team, and based on other threads, some people got to choose while others were "given" a team to continue with. How does this process look? Do the recruiters coordinate after my panel so that they offer the choice together? Assuming I pass both ofc (if I fail one or both its not too difficult of a problem 😂).
I was studying up on some (beginner) GD&T and came across this example:
I think I'm realizing I didn't fully understand FCFs... As I understood, the datums assigned to the FCF is the datums which are "touching"/"secured" during measurement. In this example, how would the position of the holes (assigned to datum B) be located while only touching the top face (assigned as datum A)? To purposefully exaggerate the idea, wouldn't the CMM just nudge our part since there is nothing constraining XY movement? I've seen other places describe datums within FCFs as what your basic dimensions draw "out" from (in reference to), which also makes sense to me (I honestly can't tell which version is right or if they are both right), but that still doesn't make sense to me in perspective of this example: how does the plane perpendicular to my hole control its position? I can understand it can control angle/perpendicularity but not the XY location...
The part I'm designing is technically a leaf spring but without sharing photos I think compliant mechanisms puts a better idea on the complexity of said spring (multiple bends, multiple "contact" points). I'll obviously be running some physical tests too but I am being asked to produce simulations to ensure the behavior will be the same in SUS as the 3D printed plastics. Looking for two things out of this: 1. Prove the behavior/exact motion of this mechanism 2. Stress analysis. At this I was thinking of just running a normal static FEA and reading the deflection but the motion is very likely not going to be linear and so it doesn't give me a great plot to show the path. It's really my first time designing springs from scratch so any starting points are welcome
I'm a college student studying ME and I feel the one big thing I don't really have a grasp on is impact loads. I understand the textbook/classroom level energy equations for impacts but I don't see how they would be applicable outside of testing or FEA.
For example, if I have a phone that needs to survive an X height drop or a robotic arm which needs to survive being hit by hammer, what is the "beam-bending-equation-equivalent" to do early calculations to prove its effectiveness prior to complex simulations?
My old ModMic 5 is finally starting to kick the bucket so I'm looking to upgrade along with my headphones. Not really interested in standalone/boom mics and would prefer a headphone attachment over a lavalier mic. Are there any new/good competitors on the scene over like the past decade?
I have another abstract and theoretical question for the subreddit. Imagine that I have a classic total runout example (2 diameters of cylindrical pins attached on the circular face to each other). Lets assume that I can provide position or the outdated concentricity if using cylindricity for sake of argument.
Now for the meat of the question. The runout callout would call the smaller cylinder in reference to Datum A, the larger cylinder. Correct me if I am wrong, but the FCF references the datum feature (being the real tangible feature) right? Since Datum A's surface also has to be controlled by some form of cylindricity, couldn't this error stack? Can this theoretically produce a looser tolerance than using cylindricity since cylindricity uses theoretically perfect surfaces as the bounding box?
