Homework Help: Find the force of compression help please!

  1. Mar 14, 2012 #1
    Find the force of tension in the chain. Determine the force of compression in the support bar. Be sure to include a free body diagram as part of your solution.

    Now the only information given is a mass=20.4 kg and the angle 22 degrees.

    If anyone could help me with this question, it would be greatly appreciated! THANK YOU SO MUCH in advance!


    This is what I attempted to do to find a solution:
    Fgravity= mg=20.4*9.8=200N

    Then to find the tension I did the following:
    Tcos(90-22degrees)-200N=0
    0.375*T=200N
    T=534N------> this would be our vertical component

    Resolving horizontally gives:
    x-Tcos(22)=0
    x=534N*0.927
    x=495N

    I did not work through your math, but it looks OK. So what is the problem? It looks like you have found your answer.

    I just wasn't feeling very confident with how I got it, I guess I was just looking for a someone to back me up on it haha thanks!
