Hello All,(adsbygoogle = window.adsbygoogle || []).push({});

I'm currently designing a lifting shackle to aid the recovery of a ROV, my problem is that I'd like to do some hand calculations to find the stresses in the shackle but I'm really not sure as to where to start.

I know how to calculate the stresses in the fixing holes but it's the point where either a hook or another shackle will be used.

I've looked all over the net and in Roark's but to no evail.

Please see the attached image.

Regards

Will
