Axial Deformation

  1. Oct 31, 2008 #1
    1. The problem statement, all variables and given/known data

    Without the 20 Kg block there is a gap of 1.5mm between B and E. The AISI 430 annealed stainless steel cable only deforms elastically. Neglect the weight of the cable and the bar. Diameter of the wire = 2 mm

    a) Find the placement of the block to reduce the gap to zero.
    b) If the weight is removed, what rise in temperature would cause the wire to sag the same amount?

    Find the attached figure for this question.

    2. Relevant equations

    I had found the area to be just 3.14 of the stel cable and then i subbed it in:

    F = [tex]\delta[/tex]*EA/L to find the force to be 3769.9 N, i duno if that is right. Then I am stuck what to do nex to find the placement of the bock to reduce the gap to zero and (b).

    3. The attempt at a solution

    Want Further help in determining the above.
