Homework Help: Normal Stress Help

  1. Sep 25, 2012 #1
    1. The problem statement, all variables and given/known data
    A 12cm X 12 cm square plate of AISI 1010 steel (E=200 GPa) us subjected to normal tensile forces of 15 kN and 20 kN on the top and right edges as shown in figure P22. The thickness of the plate is 5mm, and the left and bottom edges of the plate are fixed. Find the normal strain and deformation of the plate in the horizontal and vertical directions.

    2. Relevant equations
    Normal Stress = P/A

    3. The attempt at a solution

    I am not asking for help for the entire problem just help finding the normal stress for one.
    I am assuming P is Pascals, so I believe that P is the same Newtons? 15kN = 15000N = 15000P
    Is that part correct?
    Then I would just divide that by the area 144 cm.
