EQUILIBRIUM OF A
RIGID BODY
The body shown is
subjected to forces F1,
F2, F3 and F4. For the
body to be in
equilibrium, the
summation of all forces
acting on the body
must be equal to zero.
CHAPTER 6:
STRUCTURAL ANALYSIS
The main objective of Chapter 6 is to use the
equilibrium equations to analyze structures
which are composed of pin-connected
members.
