Purpose
Drawing a free body diagram can help determine the unknown forces on, moments applied to, and equations of motion of, the body and thus help to analyse 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.

Famous quotes containing the word purpose:
“The strongest wind cannot stagger a Spirit; it is a Spirit’s breath. A just man’s purpose cannot be split on any Grampus or material rock, but itself will split rocks till it succeeds.”
—Henry David Thoreau (1817–1862)
“Politics should share one purpose with religion: the steady emancipation of the individual through the education of his passions.”
—George F. Will (b. 1941)
“Whoever considers morality the main objective of human existence, seems to me like a person who defines the purpose of a clock as not going wrong. The first objective for a clock, is, however, that it does run; not going wrong is an additional regulative function. If not a watch’s greatest accomplishment were not going wrong, unwound watches might be the best.”
—Franz Grillparzer (1791–1872)
