Homework Help: Normal stress problem

  1. Nov 7, 2009 #1
    1. The problem statement, all variables and given/known data

    An offset link supports a load of 30 kN as shown in figure 6. Determine its required width w if the total (combined) normal stress is not to exceed 73 MPa?

    The cross section of the link is rectangular and has thickness of 40 mm

    2. Relevant equations

    stress= N/A

    I have tried many different ways to solve this problem but end up hitting a wall! any help would be greatly appreciated :)

    Hi lanedance,

    I have tried using the shearforce formula: [tex]\tau=VQ/It[/tex] but am unable to get any where...

    without being able to see the pic... why are you finding shear stress? when you want to find normal stress (Force/Area)

    wow how dumb do i look :P i have tried solving the question in every way i could think of but i am doing something wrong. I have used the normal shear formula but again to no avail.
    Thanks for the help!
