Chareyre proposed the following answer:
Hi Wang,
I tested 1).
You can find an example of a problem with bending-twisting moments in examples/test/chained-cylinder/chained-cylinder-spring.py. This example is not using spheres but it makes no difference for the Ip functor and the contact law.

Thank you for opening this discussion. It suggests there is a need for
an example script of the triaxial type with cohesive contacts and
moments.

As for how to model rolling resistance, it is by introducing bending
moments. Rolling and bending are two names for more or less the same
thing in my opinion.
