Have anyone figured out a way or developed an app that blocks apps from knowing you screenshotted ?

Because now every app has that dumb popup that says "you want to share blah blah blah" that pops up and im tired of it. I just screenshoted it if i want to share i know where it is.

Here it is, i use a lot of books when it comes to engineering for my own projects ( i use a lot of the physics concepts with good results ) i know usually when my results are coreect because i know what to expect. I use excel and a bit of matlab.

But i know i'm not fully efficient because sometimes i domt understand the relationships in the equatoons and all.

What is a good and fun way to up my math level, i have no idea where to start.

Recentely i've delved into cam profile design, i have a bit of a hard time with the complex geometry, and polynomials etc that looks scary 🤣

What software do i need to do a dynamic analysis of respnance and vibratory phenomemon of a valve spring/actuation system ?

I have ANSYS, can it handle it, or do i need something like ABAQUS or MSc Adams ?

Thanks

Any tips for applying PVA ?

I wax my mould first, and then buff it and add PVA on top usually, is it overkill ? ( epoxy CF / on a PU painted mould )

If i try with a brush, it will not wet the surface, and clump together at some random places.

I tried with a rag or sponge, it does the same.

So in the end i do it with a spray gun, in a very fine mist it works, but surface finish isnt very nice its grainy.

What can i do ?

Perhaps i can do a fine mist, let it dry then spray it thick and wet on top of the 1st fine mist, maybe it will make a nice glossy layer this way ???

How can i deal with importing a big STL file into CATIA , or convert it to surface prior to import ?

It is a car body scan , and a model off a Forza game, so quite big and i seem to be ram or graphics card limited as it crashes on SW, maybe its not as heavy for CATiA ?? .

Phone charging slow ( 9hrs ) and not wanting to take fast charge since yesterday.

Is the connector broken or something is up with the software ?

Also the charger displays error when i plug it upside down if that makes any sense.
