Homework Help: Center of gravity calculate force on tail

  1. Dec 26, 2008 #1
    1. The problem statement, all variables and given/known data

    The fore and aft distance between the two main wheels and the single tail wheel of an aircraft is 8m. The unloaded weight of the aircraft is 20kN and its centre of gravity is 0.5m behind the main wheels. Calculate the force on the tail wheel and on each main wheel.

    2. Relevant equations



    3. The attempt at a solution

    i get
    Tail Wheel = 8.45 kN Main Wheel = 1.55 kN

    I just wanted to check i had it correct becaues i am not sure.

    Thanks

    Welcome to PF!

    Hi Richardos! Welcome to PF! :wink:
    How does it not add to 20? And how is the tail wheel taking so much weight? :confused:

    Show us what you've tried, and then we'll know how to help. :smile:
