14. Importance Of Free Body DiagramImportance Of Free Body Diagram
. Drawing a free body diagram can help
us to determine the unknown forces on
moments applied and
equations of motion of the body and
thus help to analyze a problem in statics
or dynamics. In analysis of structures,
free body diagrams for a component of
a structure or part thereof are used in
determining shear forces and bending
moments.
