Work out a tensile load

  1. Aug 5, 2010 #1
    Question:

    A beam is givn with an axial strain of 500x10^-6 and a Young's modulus of 200GNm^-2. work out the magnitude of the tenslie load.

    Rlelvnt equasions:

    σ = YM x Axial strain

    My workng:

    So far I have worked out the stress of the beam to be:
    36000000Nm^2
    36MNm^2

    But from here I dont know how to get the tensile load. Is there a formula I can use?

    Picture of beam attached.

    Thnx

    Use dimensional analysis

    The same way you did it in the other thread.


    [tex]stress=\frac{Force}{Area}[/tex]

    The tensile load is the force in the above formula.
