Shear lines from a FBD with distributed forces

Click For Summary
SUMMARY

The discussion focuses on determining shear and moment functions for a Free Body Diagram (FBD) related to the load distribution on the half-wing of an airliner. Participants emphasize the importance of creating a complete FBD for each required separation and suggest that working from the wing root to the tip may be more efficient than the traditional tip-to-root approach. The conversation also highlights the need for clarity in visual aids, as some members struggled to view posted images of the FBD.

PREREQUISITES
  • Understanding of Free Body Diagrams (FBD)
  • Knowledge of shear and moment functions in structural analysis
  • Familiarity with load distribution concepts in aerodynamics
  • Basic skills in creating and interpreting engineering diagrams
NEXT STEPS
  • Research the process of creating shear and moment diagrams for structural elements
  • Explore the principles of load distribution on aircraft wings
  • Learn about the differences between working from wingtip to root versus root to tip in FBD analysis
  • Study software tools for visualizing and analyzing Free Body Diagrams
USEFUL FOR

Aerospace engineers, structural analysts, and students studying mechanics of materials will benefit from this discussion, particularly those focusing on load distribution and FBD analysis in aeronautical applications.

Homework Statement
Formulate both the V and M diagrams for the following FBD.
Relevant Equations
How would I go about this? I've looked everywhere on youtube but couldn't find a single example that used distributed forces.
, this is the FBD in question

Welcome!
I still can’t see the posted image.

Hey thanks! this should work:
I'll also add my attempt at the 4 V(m) lines and the resultant graph (which isn't correct, I do know that much)

Could you post the text of the problem?
It seems to be the load distribution on the half-wing of an airliner.

"Determine the functions for the Shear and Moment (“V & M”) lines and put these functions in a table. Choose x=0 at the wingtip, then start working from the wingtip to the wing root. Consequently use the right section of a separation. Create a complete FBD for each required separation."

My teacher mentioned during a lesson that working from tip to root was not mandatory, since the opposite is easier (apparently)
