    the salt water does make it corrode faster, but the answer couldn't be an electrolytic reaction, for the minority that actually knew what stress corrosion cracking was (not me), salt water just makes it much easier for this to happen.

    its b, not a, the brass was cold rolled, and that will cause the corrosion, not the salt water.

    How'd everyone go?

    i got 1008 W, its sq route of 20squared + 9squared to find displacement, then displacement times force, 1150N then divide by25 seconds to get power, i got 2.5mA and 43.23mm extension, hopefully thats right :S

    How'd everyone go?

    if you look up stress corrosion cracking, it pretty much explains that it has to be b, not a, too bad i chose a as well, electrolytic wouldnt work, since thats explained as something to do with an external voltage supply or something like that. 9/10 :(
