TECHNICAL NOTES

Conversation-specific knowledge extracted from the better shelf bracket design discussion.

EXTRACTED KNOWLEDGE / HOW-TO FROM CONVERSATION

QUESTION / CONTEXT: Which is a better design for a simple shelf bracket

  1. The load pushes down on the shelf.
  2. That creates a bending moment at the corner where the bracket meets the wall.
  3. The vertical piece above the shelf ends up being pulled and bent rather than compressed.
  4. Most of the stress concentrates in the inside corner.
  5. Higher bending stress
  6. More chance of the bracket flexing or the weld/fastener failing
  7. The downward load transfers into the vertical brace underneath.
  8. That brace carries the load mainly in compression, which steel handles very well.
