Complex stress situation

I am working on my bachelor thesis, and have a question regarding tension and stress distribution. My professors have shared opinions on this.

Please see picture of components:

The yellow edges submerged into the grooves can withsthand 63,5 tons each. (2 grooves = 127 tons)
The blue and yellow edge can withsthand 125 tons.
Tension snap of the yellow component will occur at 114 tons.
Shearing of the yellow component > 130 tons.
Threads, green, silver and red component > 200 tons.

Given that the dark green part is withheld, and you pull the silver part, how much force can it hold?

Will it go to failure at 63,5 tons, or will both grooves have to be deformed at 127 tons?

What's your opinion on the rating of this component - 63,5 tons, 114 tons, or 125 tons?
