This diagram isolates an object and shows all external forces and moments acting on it.
What is a free-body diagram?
This force allows water to naturally/magically flow downhill.
What is gravity?
This common diagram shows the external forces and moments acting on a single structural member.
What is a free-body diagram?

For a body in 2-D static equilibrium, the sum of forces in X, forces in Y, and this quantity must all equal zero.
What is the sum of moments?
This dimensionless number is commonly used to determine whether pipe flow is laminar or turbulent.
What is the Reynolds number?
Normal stress due to an axial force (P) is calculated using this equation.
