1. Kites team Bending

3. If the system loads by a moment on its sides this named (bending)

4. And this system can be named as a(beam)

5. The beam bends around the normal axis (z) z

6. BENDING It’s the straining of metal around a straight axis . During this process , the metal on the inside of the neutral axis is compressed , while the metal on the outside of the neutral axis is compressed , while the metal on the outside of the neutral axis is stretched Pure moment Pure bending

7. Thin beam theory Euler _Bernoulli beam theory Firstwe should have a reference to calculate the moment s y y x x

8. In these two previous cases the moment is positive according to the right hand rule

9. At pure bending moment There are some asumb: 1)The normal lines remain normal 2)Thin structure 3)Small deflection<thickness

12. Calculate second moment of area
