Shear lines from a FBD with distributed forces

Click For Summary

Homework Help Overview

The discussion revolves around analyzing shear and moment lines from a free body diagram (FBD) involving distributed forces, specifically related to the load distribution on the half-wing of an airliner.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the visibility of the posted FBD and the original poster's attempt at identifying shear and moment lines. There are inquiries about the problem text and the approach to determining shear and moment functions, with some questioning the necessity of working from the wingtip to the wing root.

Discussion Status

The discussion is ongoing, with participants seeking clarification on the problem statement and exploring different approaches to the analysis. Some guidance has been offered regarding the direction of analysis, but no consensus has been reached on the best method to proceed.

Contextual Notes

Participants note that the original poster's teacher suggested that starting from the wing root might be easier than the proposed method of starting from the wingtip, indicating a potential assumption about the preferred approach.

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

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)
