  • Loads
  • 8

    1. 1. Kites team <br />Bending<br />
    2. 2. Introduction<br /><ul><li>We saw in previous chapters that we can sort the loads that act on the truss or system .
    3. 3. If the system loads by a moment on its sides this named (bending)
    4. 4. And this system can be named as a(beam)
    5. 5. The beam bends around the normal axis (z)</li></ul> z<br />
    6. 6. BENDING<br />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 <br />Pure moment<br />Pure bending<br />
    7. 7. Thin beam theory<br />Euler _Bernoulli beam theory<br />Firstwe should have a reference to calculate the moment <br /> s<br />y<br /> y<br />x<br />x<br />
    8. 8. In these two previous cases the moment is positive according to the right hand rule<br />
    9. 9. At pure bending moment<br />There are some asumb:<br />1)The normal lines remain normal<br />2)Thin structure<br />3)Small deflection<thickness<br />
    10. 10.
    11. 11.
    12. 12. Calculate second moment of area <br />
