    There are several ideas floating about but take a look at the unofficial mark scheme on this thread
    Do you agree with the unofficial mark scheme response, its the best I could come up with but I can find nothing on the Internet.

    I simply stated that concrete contained strong bonds, then explained crack propagation. Is stress still concentrated at the tip of the crack if it is being compressed rather than stretched/bent?

    As far as I think, the crack should not appear under compression, as the bonds aren't being pulled apart. Might be wrong though

    Sorry! didnt see that.. have you had your exam yet? if so how'd it go?

    if not then I dunno if youve done loads of exam papers you should be fine!
    they pretty much just put the same questions in every year with a couple of different situations..

    if you get stuck have a proper look through your formula booklet and check that there is definitly not a formula to help you ( theres usually one that helps in there...) thats all the advice i can give really have a good sleep too
