    I am a little (lot) rusty on my statics. In the case of a B&R type rig with reverse diagonals, how does one go about calculating shroud loads, or more precisely, what sort of FBD do you come up with?

    With a standard rig, it's fairly straight forward, but the B&R rig has me stumped at the moment.

    Method of Joints seems to have too many reactions at some nodes to solve.
    Method of Sections, I'm not sure where to make the cut since IIRC, you can only cut through 3 members. The boundary reactions are easy to resolve.

    As mentioned, I am quite rusty in all this stuff, so some guidance would be much appreciated.

    The method of sections can cut through more than 3 members. However, you may have to use moments to solve it.
