Free Body Diagram - Purpose

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:

    In using the strong hand, as now compelled to do, the government has a difficult duty to perform. At the very best, it will by turns do both too little and too much. It can properly have no motive of revenge, no purpose to punish merely for punishment’s sake. While we must, by all available means, prevent the overthrow of the government, we should avoid planting and cultivating too many thorns in the bosom of society.
    Abraham Lincoln (1809–1865)

    The United States is the only great nation whose government is operated without a budget. The fact is to be the more striking when it is considered that budgets and budget procedures are the outgrowth of democratic doctrines and have an important part in developing the modern constitutional rights.... The constitutional purpose of a budget is to make government responsive to public opinion and responsible for its acts.
    William Howard Taft (1857–1930)

    Natural selection, the blind, unconscious, automatic process which Darwin discovered, and which we now know is the explanation for the existence and apparently purposeful form of all life, has no purpose in mind. It has no mind and no mind’s eye. It does not plan for the future. It has no vision, no foresight, no sight at all. If it can be said to play the role of the watchmaker in nature, it is the blind watchmaker.
    Richard Dawkins (b. 1941)
