Fundamentals of Statics (Equilibrium Analysis)
Statics is the branch of mechanics that deals with physical systems in equilibrium. Understanding how forces and moments interact is the foundation for all structural analysis and machine design.
Governing Formula
ΣF = 0 , ΣM = 0ΣFSum of all forces (N)
ΣMSum of all moments (Nm)
Step-by-Step Calculation
- 1Identify all external forces acting on the body.
- 2Draw a Free Body Diagram (FBD).
- 3Resolve forces into X, Y, and Z components.
- 4Apply equilibrium equations: ΣFx=0, ΣFy=0.
- 5Sum moments about a point to find unknowns: ΣM=0.
Worked Example
Input Parameters
- Force 1: 100 N (Up)
- Reaction 1: R1 (Down)
Calculation
ΣFy = 100 - R1 = 0 → R1 = 100 N
Why This Matters
- Ensures structures and machines can withstand applied loads without moving or failing.
- Allows for the calculation of reaction forces at supports.
Common Mistakes
- Failing to include all forces in the Free Body Diagram.
- Incorrectly identifying the direction (sign) of forces or moments.
- Neglecting the weight of the object when it is significant.

Technical Q&A
What is a moment?
A moment is a measure of the tendency of a force to cause a body to rotate about a specific point or axis.
