Trusses

Notes 2

 "TRUSSES"

About Trusses :

1-Axial loads only
2-Loads applies at end points only
3- Elements are joined by pins only

1-Determine the force in each member of the truss ?

2-Determine the force in each member of the truss and indicate whether the the members are in tension or compression ?

3-Determine the force in each member of the truss and indicate whether the the members are in tension or compression ?

At joint A :

At joint C :

At joint D :

4-Determine the force in each member of the truss and indicate whether the the members are in tension or compression ?

At joint B :
a

At joint C :
a

At joint A :
a

* The Method of Sections :

6-Determine the force in each member of the truss and indicate whether the the members are in tension or compression ?

 Method of joints : We will begin analyzing the Equilibrium of joint D , and the proceed to analyze joints C & D .

Note : The equilibrium analysis of joint A can be used to determine the components of support reaction at A .
