BUG: Member.Beam is used as static method, but not defined as static

[ZTThomasOberthanner]

Describe the bug
in member.py the method Member.Beam is defined as an instance method with self as first argument
def Beam(self,

but in test_member.py Member.Beam is used like a static/class method of the Member Class
Member.Beam(0, 1, 1, 2, MemberSectionDistributionType.SECTION_DISTRIBUTION_TYPE_UNIFORM, MemberRotationSpecificationType.COORDINATE_SYSTEM_ROTATION_VIA_ANGLE, [0.2618], 1, 1)
with 0 as an additional parameter for self and not as an instance method

Expected behavior
Member.Beam should be defined as a static method without self as first argument

@staticmethod
def Beam(no: int = 1,

As all the arguments to this method have default values, using kwargs is a great thing to produce readable code like this:

Member.Beam(
            no=1,
            start_node_no=1,
            end_node_no=2,
            start_section_no=1,
        )

this raises an error because self is not defined.

btw:
rotation_parameters = [0], is again an example for a mutable default argument

This is just an example for this design pattern that is used on many locations

Hi @ZTThomasOberthanner,
thank you for the input. We missed it in the beginning for some reason and forget to fix it later. Good job! I will handle it.

As for dangerous defaults (mutable arguments), it is dangerous only if the argument is changed. In our application, the value is only passed to the client, so it's really not a problem. We agreed that it is useful for less experienced users to understand the correct form of the parameter instead of creating long descriptions.
This still doesn't mean that we stop enhancing the methods along the way and removing some of the default mutable arguments to enhance the experience.
