Homework Help: Statics Allowable load problem.

  1. May 2, 2012 #1
    1. The problem statement, all variables and given/known data
    Determine allowable load on steel tube

    L= 14 in
    A= 11 in ^2
    Es= 30 x10^6
    θ=24,000 psi
    δ= .008

    2. Relevant equations

    3. The attempt at a solution

    .008=P(14 in)/(30 x 10^6)(11 in)^2

    P=188571.4 lb

    24,000 psi=P/11 in^2


    My teach is telling me that the answer is P=2181.8 lbs i dont understand how or what i did wrong

    I dont understand either if the load is axial tensile. Is it?
