Shear force and Bending moment of a Cantilever Rod

Click For Summary

Discussion Overview

The discussion revolves around calculating the shear forces at points A and B, as well as the bending moment at point C of a cantilever rod subjected to a load. The context includes technical reasoning related to mechanics and structural analysis.

Discussion Character

  • Technical explanation
  • Homework-related

Main Points Raised

  • The original poster describes a cantilever rod at a 45-degree angle with a specified load force and distances from the load to points A and B.
  • Some participants suggest that the original poster must provide relevant equations and show their work for verification.
  • One participant states that it may not be possible to find the shear forces at points A and B directly, but suggests that the shear force between A and B can be determined, prompting a question about which definition of shear force to use.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the ability to find the shear forces at points A and B, indicating that multiple views on the definitions and calculations of shear force exist.

Contextual Notes

The discussion lacks specific equations and detailed calculations, which may limit the ability to resolve the problem fully. The definitions of shear force mentioned are not specified, leaving room for interpretation.

1. I have a rod as pictured in the attachment. The rod is at a 45 degree angle.
The load force is 115.118lbf
The force is y-direction is 97.954lbf

The Force at A is 5 inches from Force in the y-direction.
The force at B is 10.5 inches from the Force in the y-direction

I need to find the shear forces for A and B and the moment at point C

I am stuck at the shear forces (V)

Thanks for the help

Plz help I messed up here
 
kgprice11: You must list relevant equations yourself, and show your work. And then someone might check your math.
 
You will not be able to find the shear forces at A and at B. But you will be able to find the shear force between A and B. Which definition of shear force do you prefer to use? (there are at least two)
