Angles in a chair o plane

  1. Jun 8, 2012 #1
    1. The problem statement, all variables and given/known data
    The chair o plan seats are supported by chains hung from a circular structure. What angle to the vertical will be formed by the chain of a chair-o-plane seat is occupied by a 45 kg child if the tension is 550 N... I was able to solve this one.. THe question I need a help in is this: A nearby chair is occupied by a 90kg man. Explain why the angle formed by the chain will be the same as for the child... Mathematically, i feel this question is in apropiate.. If we say T cos theta is (mg) so by altering m , the angle changes too .. Isn't it.. if not, I need the correct answer..


    2. Relevant equations



    3. The attempt at a solution

    I think you will find that you had to use 2 equations to find the angle θ.
    Vertical component of tension = TCosθ = mg
    and horizontal component TSinθ = mv^2/r
    Put these together (to get Tanθ)..... see what happens?
