Shear force bending moments diagram help?

Click For Summary
SUMMARY

The discussion focuses on the process of drawing shear force and bending moment diagrams in structural analysis, specifically addressing homework problem number 4. The user expresses uncertainty about the inclusion of moments in their diagrams, noting that their bending moment diagram does not return to zero. Key equations referenced include ΣmomentA= 0, ΣFx= 0, and ΣFy= 0. The user seeks clarification on calculating maximum shear force, which is not covered in their textbook.

PREREQUISITES
  • Understanding of static equilibrium equations (ΣmomentA= 0, ΣFx= 0, ΣFy= 0)
  • Familiarity with shear force and bending moment diagrams
  • Knowledge of concentrated forces and their effects on diagrams
  • Basic principles of structural analysis
NEXT STEPS
  • Study the process of drawing shear force diagrams using examples
  • Learn how to construct bending moment diagrams with included moments
  • Research methods for calculating maximum shear force in beams
  • Explore resources on static equilibrium in structural engineering
USEFUL FOR

Students in civil or structural engineering, educators teaching mechanics of materials, and professionals involved in structural analysis and design.

The Attempt at a Solution

i've got the correct answers i think, but I'm not sure how to draw the shear force and bending moment diagrams because of the moment that's included. i did draw them but it didn't seem correct because the bending moment diagram never went back to 0.

Also What is the maximum shear force and how do i work it out it doesn't say anything about it in my book?

The moment will only appear on the Bending Moment diagram, and just like a concentrated force produces a discontinuity in the shear force diagram, the moment will do the same for the bending moment diagram.
