Engine-out procedures and eccentric forces on engine pylons

You should see what those pylons do in heavy turbulence!
The only stress is on the pilot who looks at them. :-)

I've seen engine nacelles swaying merrily to and fro (along the wing
axis) in turbulence but I didn't know if twisting forces applied to
the pylons would be so easily tolerated.

I.m wondering if the engineering on wings has changed a bit. I worked for
an airline carrier in the early 60's and we took deliver of the first
boeing 727 built. the company provied us with a very similar video. Its
showed a 727 straped into a cradel and the wings were bent up similar to
what this utube shows..
Difference:
i watched the wings pushed up to where both tips touched each other many
many many times
there was not a failur and i do not remeber exactly how many times but it
was in the dozens. I wonder what the difference is that this wing breaks
after only one raise

Nope, essentially the same up to the point where they're sticking
Carbon fiber spars in, but the certification standards are the same.

A wing pylon will happily accept a consideraable load in just about
any flight attitude, what it won't accept is s sudden high G load such
as extreme turbulence or an abrupt engine stoppage might cause.
you won't break a wing off too easily, though.
