Homework Statement



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

Homework 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 ashley, welcome to pf

can't see the pic yet, they usually take a while to claar, what have you tried?
 
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!
 

Thread 'Initial conditions for orbits around a wormhole'

Hi, I had an exam and I completely messed up a problem. Especially one part which was necessary for the rest of the problem. Basically, I have a wormhole metric: $$(ds)^2 = -(dt)^2 + (dr)^2 + (r^2 + b^2)( (d\theta)^2 + sin^2 \theta (d\phi)^2 )$$ Where ##b=1## with an orbit only in the equatorial plane. We also know from the question that the orbit must satisfy this relationship: $$\varepsilon = \frac{1}{2} (\frac{dr}{d\tau})^2 + V_{eff}(r)$$ Ultimately, I was tasked to find the initial...

Thread 'Help to convert units of a simple formula'

The value of H equals ## 10^{3}## in natural units, According to : https://en.wikipedia.org/wiki/Natural_units, ## t \sim 10^{-21} sec = 10^{21} Hz ##, and since ## \text{GeV} \sim 10^{24} \text{Hz } ##, ## GeV \sim 10^{24} \times 10^{-21} = 10^3 ## in natural units. So is this conversion correct? Also in the above formula, can I convert H to that natural units , since it’s a constant, while keeping k in Hz ?
