EXTRACTED KNOWLEDGE / HOW-TOFROM CONVERSATION
QUESTION / CONTEXTWhich is a better design for a simple shelf bracket
IMPORTANT GUIDANCE
- The load pushes down on the shelf.
- That creates a bending moment at the corner where the bracket meets the wall.
- The vertical piece above the shelf ends up being pulled and bent rather than compressed.
- Most of the stress concentrates in the inside corner.
- Higher bending stress
- More chance of the bracket flexing or the weld/fastener failing
- The downward load transfers into the vertical brace underneath.
- That brace carries the load mainly in compression, which steel handles very well.
