SUMMARY

The discussion focuses on solving a cantilever beam problem with an end load of 20kN, an EI value of 40 KNm², and a length of 0.25m. The fundamental equation used is d²y/dx² = M/EI, where M represents the moment due to the load. Participants emphasize the need to integrate this equation to find the slope at the free end of the beam, clarifying that the slope corresponds to the first derivative of the deflection curve.

PREREQUISITES
  • Understanding of cantilever beam mechanics
  • Familiarity with differential equations
  • Knowledge of the relationship between moment and deflection
  • Experience with integration techniques in engineering
NEXT STEPS
  • Study the integration of differential equations in structural analysis
  • Learn about the moment-curvature relationship in beam theory
  • Explore the use of boundary conditions in cantilever beam problems
  • Review the mechanics of materials textbook for detailed explanations of slope and deflection
USEFUL FOR

Engineering students, structural analysts, and professionals involved in beam design and analysis will benefit from this discussion.

Homework Statement



A cantilever beam carriers an end load of 20kN and has an EI value of 40 KNm^2. If the beam is 0.25m long, use intergration to determine

the slope at the free end of the beam?



Homework Equations



I know from a handout I have that the fudamental equation to use is

d^2y/dx^2 = M/EI

when I substitute this I get EI X d^2y/dx^2 = WU(l - x)

This is where I am stuck? Any help much appricated

Hint: the slope means 'first derivative', i.e. the rotation of the cross section of the beam.
 
Not with you? I think you have to intergrate it but Not sure how many times though.
 
Do you know what the y means in that differential equation? open up your mechanics of materials book and look it up, then you'll understand what radou said.
