Discussion Overview
The discussion centers around determining the maximum weight that a 1" thick steel plate (A36) with a 1.125" hole can support when a 1" grade 8 bolt is subjected to a downward force, specifically in the context of a weldment. Participants explore the relevant calculations and considerations for plate thickness and bolt size under significant load.
Discussion Character
- Homework-related
- Technical explanation
- Debate/contested
Main Points Raised
- One participant inquires about the application and requests a sketch or CAD drawing to better understand the setup.
- Another participant mentions a force of 30,000 lbs pulling straight down on the bolt and questions the consequences of a potential failure of the bolt or plate.
- A participant clarifies that the actual load will be about 22,500 lbs and seeks information on the force that a 1" plate could hold, considering the possibility of using thicker plates if necessary.
- Concerns are raised about relying on internet discussions for critical design decisions, suggesting the need for professional engineering input.
- One participant expresses frustration over perceived lack of assistance and emphasizes their prior understanding of physics and material strengths.
- Another participant mentions standard formulas and tables for bolt requirements in structural applications, but notes that the original question pertains specifically to the shear strength of a single bolt through a plate.
- There is a disagreement regarding whether the discussion pertains to tensile strength or plate shear, with participants asserting differing views on the relevant mechanics.
- The discussion is ultimately locked due to its classification as a "Dangerous Discussion," advising consultation with a local engineer for safety and compliance issues.
Areas of Agreement / Disagreement
Participants express differing views on the appropriate calculations and considerations for the load-bearing capacity of the plate and bolt. There is no consensus on the best approach to determine the shear strength or the necessity of professional engineering guidance.
Contextual Notes
The discussion highlights the limitations of relying on online forums for critical engineering design questions, particularly given the significant load involved and the potential safety implications.
