Elevator falls when I am inside

  1. Sep 22, 2005 #1
    My schools building has 6 stories, I usually have to go up to 6th storey to meet my teacher.
    That buildign elevator is old and it sounds terrible when it moves up or down.
    I don't want to use stairs because I will be very tired.
    I am 180 cm tall, my weight is 80kgs.
    What should I do if the elevator of my school falls when I am inside ?
    How badly does my legs bone get broken ? I am a bit worried.
    Thank you.........

    Hello, thank you
    that is really good suggestions

    But I am thinking, if the elevator is down with v [m/s], ratio for bone broken with a given retarded force f is alpha, knowing that v increase more and more till it and I hit the ground, also knowing that I am with the height and weight as said above, can you help me calculate f that will go againts both of my legs? Thank you

    Oh, I see:

    "Please help fool the teacher into thinking I know this so I won't have to actually learn anything."

    I'm afraid you're not going to get a whole lot of help with that here- we don't dislike you that much.

    Hmm, go rent the mythbusters episode where they dropped an elevator. Actually, if you're really worried about this, probably better not.

    You do know that elevators have safety brakes, right?

    is this a homework question?

    or do you just want to know your chance of survival just for the heck of it
