  2. Free body diagram - Wikipedia

    en.wikipedia.org/wiki/Free_body_diagram

    A free body diagram is not a scaled drawing, it is a diagram. The symbols used in a free body diagram depends upon how a body is modeled. [6] Free body diagrams consist of: A simplified version of the body (often a dot or a box) Forces shown as straight arrows pointing in the direction they act on the body

  3. Cremona diagram - Wikipedia

    en.wikipedia.org/wiki/Cremona_diagram

    The same steps can be taken for joints D, H and E resulting in the complete Cremona diagram where the internal forces in all members are known. In a next phase the forces caused by wind must be considered. Wind will cause pressure on the upwind side of a roof (and truss) and suction on the downwind side. This will translate to asymmetrical ...

    Free body diagram of a statically indeterminate beam In the beam construction on the right, the four unknown reactions are V A , V B , V C , and H A . The equilibrium equations are: [ 2 ]

  5. Structural analysis - Wikipedia

    en.wikipedia.org/wiki/Structural_analysis

    In the context to structural analysis, a structure refers to a body or system of connected parts used to support a load. Important examples related to Civil Engineering include buildings, bridges, and towers; and in other branches of engineering, ship and aircraft frames, tanks, pressure vessels, mechanical systems, and electrical supporting structures are important.

  6. Truss - Wikipedia

    en.wikipedia.org/wiki/Truss

    Given a certain number of joints, this is the minimum number of members, in the sense that if any member is taken out (or fails), then the truss as a whole fails. While the relation (a) is necessary, it is not sufficient for stability, which also depends on the truss geometry, support conditions and the load carrying capacity of the members.

  7. Freeform surface modelling - Wikipedia

    en.wikipedia.org/wiki/Freeform_surface_modelling

    Freeform surface modelling is a technique for engineering freeform surfaces with a CAD or CAID system.. The technology has encompassed two main fields. Either creating aesthetic surfaces (class A surfaces) that also perform a function; for example, car bodies and consumer product outer forms, or technical surfaces for components such as gas turbine blades and other fluid dynamic engineering ...

    Alabama A&M freshman linebacker Medrick Burnett Jr. died one month after sustaining a head injury in an Oct. 29 game. He was hospitalized for the entire past month.

  9. Influence line - Wikipedia

    en.wikipedia.org/wiki/Influence_line

    The bending moment diagram and the influence line for bending moment at the centre of the left-hand span, B, are shown. In engineering, an influence line graphs the variation of a function (such as the shear, moment etc. felt in a structural member) at a specific point on a beam or truss caused by a unit load placed at any point along the ...
