    1. The problem statement, all variables and given/known data

    [​IMG]

    3. The attempt at a solution

    (i) Is the weight balanced on both sides in a situation like this, in which case it would be:

    Or are the weights not equal and infact im meant to work it out with dimensions in terms of letters, for example A-C?

    ------------------------------------------------------------------------------

    (ii) Could anyone tell me where i can learn about these support structures, i brought a mechanics book but it doesnt cover and after looking on the internet i cant find any good sources of information to teach me.

    Hi Spadez! :smile:

    No, they're not equal.

    Hint: take a moment.

    Ok, so i take moments but i have to use the distance with respect to the letters, im not given any distances. Can i still do it like that?

    hmm … assuming the triangles are all the same, just say "let AC = CE = EG = 1 unit" … the units will cancel in the end :smile:
