Fix Pushover Analysis Example

[jonbiemond]

Pass plastic_beam in via a default argument to avoid a NameError when called in another module during analysis.

Lambda functions only have access to the scope of the environment they are called in. Any additional variables from where they are defined must be explicitly passed in.

Resolves #325

Thanks for the contribution. I can see why this approach is useful in your case, and I don’t think there’s anything wrong with it technically.

For this example, though, I’d like to keep the code as simple and approachable as possible. Most new users won’t be calling the example from another module, so adding the explicit frame=frame argument introduces an extra concept that may create more confusion than clarity.

Because this seems specific to your workflow rather than something broadly needed by most users, I’m hesitant to incorporate it into the general example problem. I appreciate you pointing it out, though.

Hi @JWock82, sorry for not explaining correctly. The example does not work as is, unless pasted directly into a library file and ran from there.
