Problem: I am analyzing the structural integrity of this V-shaped bookshelf to prevent collapse under heavy loads. From a mechanical perspective, identify the specific component that must act as the primary load-bearing 'anchor' for the entire system. Furthermore, assuming I am a beginner who must avoid external brackets and complex joinery, which specific internal connection method—designed to transfer weight directly into that anchor—provides the highest strength-to-difficulty ratio?
Answer: The central vertical spine (or back panel); dado or groove joints.
