    Need help with physics problem.

    Hello guys, im kinda stuck with this physics problem because i've forgotten a lot since i last needed to do this but i have to do it now so i would appreciate some help. Sorry for the blurry images, had to use my phone to take the photos. What i need to do is find the forces and the moments but im not quite sure how to do it.

    Here i need to find Fah and Fbh, F2h and F3h are known. Also the moments in points A,2,3 and B.

    Same here, need Fav and Fbv, F1v, F2v, F3v and F4v are known. Also the moments in points A,2,3 and B.

    This is basically what i need to calculate, FA, FB and the total moment in all points. h is for horizontal, v - vertical.

    I can't read cyrillic. Fs are forces in this example, yes?

    In fact, I'm in the dark on a lot of this... L is liters?

    So something is floating and you're trying to find a buoyant force?

    Please translate the entire thing for those of us who don't understand the language.

    Yes, F is the force and L is the length , D is the diameter, the text is not important, mainly says that u need to find the forces and moments through a lot of bullshit text.

    And no its not a body in water, it's this shaft

    I'll be very honest with you. I'm a Physics major but I've never done a problem like that with that diagram, and since I can't really read the text I don't get a good understanding. If this was in English, I'd tell you to take pictures of your notes and I'd try to help by reading the notes then doing the problem, but that is not the case.

    If it's a matter of math, I'll do that for you no problem.

    Eh let me look it over some more.

    Ye it's the math, i dunno if to get Fah it's Fah=-F2h or -F2h-F3h, and to get the moment in point B it's -F1v+F2v+F3v+F4v etc... That's what im confused about since i havent done things like this in 2 years
