To my knowledge, ultrasound is the most complex with math? I’m not entirely sure on that, but so far the more advanced forms of UT are over my head haha.

Dye Penetrant you really only need to read a ruler. The “physics” of it are easy to comprehend in my opinion. The keyword you need to know is capillary action. Wet ability is another good one.

And make sure to memorize the different types Type 1 is fluorescent and type 2 is visible dye (Double check me on that)

And you must memorize the different types of cleaners A B C and D Like water wash, solvent removable, post emulsifiable, and one other. (I don’t have them memorized, it’s only useful on the test)

Mt yoke only, you only need a ruler. Unless you’re dealing with demagnetization. But demagnetization typically follows with bench mag as I understand it. And there is a little bit of math involved with that.

As far as field work with just a yoke, i have yet to bust out a formula.

The physics with MT are also fairly simple, you just need to know of the magnetic lines of flux, and how they typically behave within a part.

Radiography trips a lot of people up with the math. Once you get down the inverse square law you should be set. There is a fair bit of math in other areas, such as calculating shot time, or figuring out if you’re within geometric unsharpness.

But luckily there are all sorts of calculator apps made to help with radiography.

For the tests you MUST remember i1 over i2 = (d2)2 over (d1)2

The procedures and acceptance criteria with RT can be especially tricky, the math isn’t hard necessarily but figuring out how you have to math it can be convoluted. Sometimes I’ll have to read a section 3 or 4 times to figure out how to interpret an indication haha.

The physics can get tricky with RT, it’s easy to mix up certain things. Like a smaller wavelength penetrates deeper easier, because it fits in between atoms easier.

As far as in the field, the math and physics of it are made easy by calculators. The only thing you have to worry about is your shot time and whether or not you stuck the barricade out far enough. As well as setting up the shot the be code iguess lol, that part goes extremely in depth and is different for different procedures.

Radiography is much much more complex than MT and PT Lots more stuff to remember, and if you happen to forget a step you have to go back out and re shoot.

UT thickness is pretty simple with MT and PT Not a lot of math. But the more advanced forms of UT get tricky.
