What we have learnt
- Beams subjected to transverse loads experience bending and deflection, which must be measured for structural integrity.
- The Euler-Bernoulli beam theory provides the governing equation for beam deflection, linking bending moment and deflection.
- Various methods such as the double integration method and moment area method are essential for computing deflections and slopes.
Key Concepts
- -- Beam Deflection
- The displacement of a structural beam under transverse loading, particularly critical for maintaining structural integrity and usability.
- -- EulerBernoulli Beam Theory
- A classical beam theory that describes the relationship between bending moments and deflection using a second-order differential equation.
- -- Double Integration Method
- A method used to calculate deflection by integrating the bending moment equation twice and applying boundary conditions.
- -- Moment Area Method
- A technique that leverages the area under the moment diagram to find changes in slope and deflection between points on a beam.
- -- Common Loading Cases
- Specific configurations of loads applied to beams that have established maximum deflection formulas for practical use.
