AS Level Physics coursework help!

  1. Feb 2, 2010 #1
    1. The problem statement, all variables and given/known data

    The coursework i'm doing is about the efficiency of elevators. It's simple enough, but I have to outline some points in my coursework summary and there's nothing relevant to them on the internet.


    2. Relevant equations

    N/A

    3. The attempt at a solution

    One of the questions is "Outline the problems that need to be overcome when installing elevators in very tall skyscrapers"

    There's no resources i can refer to in books or on the internet. I'm really not sure what they're looking for.

    Problems with tall elevators:

    -cable weight becomes a problem
    -cable elasticity becomes a problem
    -acceleration vs speed
    -wind (pressure difference between ground and top floor will make a lot of it if not sealed)
    -too many buttons for me
