Homework Help: Can't find normal and tension force please help

  1. May 23, 2004 #1
    i have two problems here where i have to find individual forces.

    problem 1: i can't find the normal force. how would i do it?

    Code (Text):
    <img src=[PLAIN]http://img1.photobucket.com/albums/0903/badboyben03/p01.png>
    [/PLAIN] [Broken]
    i tried 2123.328N *(2825.008-701.68) and also tried 701.68N but neither of them worked.

    problem 2: i can't find the tension force

    Code (Text):
    <img src=[PLAIN]http://img1.photobucket.com/albums/0903/badboyben03/p03.png>
    [/PLAIN] [Broken]
    i tried 32.438N and 132.948 *(165.386-32.438) but also neither of them worked.

    please help me. thanks.

    Problem 1.
    The normal force must produce the required centripetal acceleration.
    This is also the case with problem 3.

    Problem 1: Remember that in Newton's 2nd law, Fnet is a vector sum that reduces to (in this problem):
    Fnet = Fnorm-Fgrav
    Plug in your values appropriately to solve for the normal force on the pilot.

    Problem 2: Same exact idea. You need to consider the directions of each force in order to add them together.
