Calculating Bending Moment and Using Virtual Work Principle for Cantilever Beam

Click For Summary
SUMMARY

The discussion focuses on calculating the bending moment for a cantilever beam using the principle of virtual work. Participants emphasize the importance of first establishing the bending moment equation before applying the virtual work principle. Additionally, they highlight the need to understand shear force calculations derived from distributed loads. A foundational knowledge of strength of materials is deemed essential for effective problem-solving in this context.

PREREQUISITES
  • Understanding of bending moment equations
  • Familiarity with the principle of virtual work
  • Knowledge of shear force calculations from distributed loads

Homework Equations





The Attempt at a Solution



I think #1 is to find the bending moment equation, then use the principle of virtual work. I have no idea how to find the bending moment equation and which principle of virtual work to use. Any guidance would be appreciated.

What about the shear force? Can you find shear from the given distributed load?

Have you studied any strength of material?
 
Do you have a working definition of 'bending moment'? Are you able at least to calculate the total load? Answers to these 2 questions would be a valuable starting point, in addition to SteamKing's suggestion.
