Deformation Caused By Tightening A Nut

  1. Sep 18, 2011 #1
    1. The problem statement, all variables and given/known data


    2. Relevant equations
    [itex]\delta[/itex] = PL/AE

    3. The attempt at a solution
    As you can see I know that [itex]F_{cd}[/itex] is related to [itex]F_{be}[/itex]
    and a second relationship can be found by the geometry of the deformations.
    I end up with [itex]F_{cd}[/itex] = [itex]11.9^{kN}[/itex] but the answer is supposed to be
    9.73 kN.

    I am unsure when it comes to finding the deformation in CD. I'm not sure if the deformation is expressed correctly. My reasoning is: tightening the bolt causes a 'positive' deformation and a 'negative' deformation comes from compressing the bolt.
