To cover all aspects effectively, I will perform multiple searches simultaneously: one for the general keyword, one for MHH Auto context, one for SFD calculation methods, one for free resources, one for VAG SFD in automotive diagnostics, and one for possible Excel templates. search results show that the keyword has two main interpretations: structural engineering (Shear Force Diagram) and automotive diagnostics (VAG SFD protection). The user's keyword includes "VAG" and "MHH Auto," which points strongly to the automotive context. The results include several MHH Auto forum threads. To fully understand the user's needs, I need to open multiple relevant results simultaneously.
