QUESTIONS

1. Explain MeCaulay’s method for finding out the slopes and deflection of a beam.
2. What is the central deflection of a simply supported beam of span l when two equal moments of M_o applied at ends?
3. Derive a relationship between deflection, BM and flexural rigidity for a beam.
4. Explain conjugate beam method. Draw the conjugate beam for a cantilever beam fixed at right end and loaded with central point load.
5. State moment–area theorems. How they are different from conjugate beam theorems?
6. Discuss double integration method of finding deflection of beams.
7. Using double integration method, find the deflection under the loads of the beam shown in Figure 8.38.
