Module 2 :Analysis of Statically Determinate Structures
Lecture 9 :Example for Trusses
(a)FBD of the jointB:
FBD of the jointA:
Force inAB= 22.5kN(Compression).
Force inAD= 37.5kN(Tension).
Force inAC= 30.0kN(Compression).
(b)Take a section throughEG,FG,FHand consider the equilibrium of part at the right side
Force inEG= 36.0kN(Compression).
Force inFG= 22.5kN(Tension).
Force inFH= 18.0kN(Compression).
