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: $$\tau=VQ/It$$ 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!
