Stress in bracket distributed eccentric load

Click For Summary

Discussion Overview

The discussion revolves around analyzing stress in a bracket designed to support an eccentric load. Participants are exploring the appropriate free body diagram (FBD) to use for calculating bending moments and axial loads at a specific point of interest in the bracket's design.

Discussion Character

  • Homework-related
  • Technical explanation

Main Points Raised

  • One participant has designed a bracket and is seeking assistance in determining the correct FBD to analyze the stress at a specific point under an eccentric load.
  • Another participant suggests that a clearer and more detailed 3D sketch of the bracket would aid in understanding the problem better.
  • A participant shares a sketch that illustrates how the bracket straps to a tube, which is the component that experiences impact.
  • One participant mentions having run a finite element analysis (FEA) for exploratory purposes, though details on the results are not provided.

Areas of Agreement / Disagreement

The discussion does not indicate any consensus among participants regarding the correct FBD to use or the specifics of the stress analysis, as various suggestions and clarifications are being made without resolution.

Contextual Notes

Participants have not provided specific assumptions or definitions that may affect the analysis, and the discussion lacks detailed mathematical steps or results from the FEA mentioned.

Homework Statement


I have designed a bracket and am interested in stress at a certain point. I have figured out the load needed to support. The area of interest carries an eccentric load so bending moment and axial load need to be figured out. Not sure which FBD is correct to use.

Sketch the bracket more clearly and in 3D so that we can understand the problem better .
 
This shows how it straps the tube. The tube is what gets hit.

Ran an FEA for fun.
