Why do some electricity pylons collapse in extreme temperatures ?

  1. Nov 19, 2013 #1
    1. The problem statement, all variables and given/known data

    Using physics knowlege, why do some electricity pylons collapse in extreme temperatures.

    2. Relevant equations



    3. The attempt at a solution
    Don't know the physics formulas or equations that could be used. High winds would force the pylons to collapse as the structure hasn't been made to withstand highwinds of extreme speeds. Also snow could fall on them turning to ice making them heavy and then collapsing. Not sure how to explain this in physics terms. answer is for 3 marks in SQA National 5 Physics (Scotland)

    Thank you so much

    Is this a question from a current SQA National 5 Physics test?

    Electric pylons and extreme weather

    It is from the sqa specimen paper on the sqa website, but the answer states its open ended with no more hints.

    Okay. Just checking.

    Think about what materials make up pylons and what they are connected to. How do temperature changes affect those materials?
