    The five paragraph order or five paragraph field order is a style of organizing information about a military situation for a unit in the field. It is an element of Canadian Army, United States Army, United States Marine Corps and United States Navy Seabees small unit tactics, and similar order styles are used by military groups around the world.

  3. Technical drawing - Wikipedia

    en.wikipedia.org/wiki/Technical_drawing

    An example of a drawing drafted in AutoCAD. 2D CAD systems such as AutoCAD or MicroStation replace the paper drawing discipline. The lines, circles, arcs, and curves are created within the software. It is down to the technical drawing skill of the user to produce the drawing.

    CAD is an example of the pervasive effect computers were beginning to have on the industry. Current computer-aided design software packages range from 2D vector -based drafting systems to 3D solid and surface modelers .

  6. Size effect on structural strength - Wikipedia

    en.wikipedia.org/wiki/Size_Effect_on_Structural...

    The structural size effect concerns structures made of the same material, with the same microstructure. It must be distinguished from the size effect of material inhomogeneities, particularly the Hall-Petch effect, which describes how the material strength increases with decreasing grain size in polycrystalline metals.

    The Eiffel Tower in Paris is a historical achievement of structural engineering.. Structural engineering is a sub-discipline of civil engineering in which structural engineers are trained to design the 'bones and joints' that create the form and shape of human-made structures.

  9. Solid solution strengthening - Wikipedia

    en.wikipedia.org/wiki/Solid_solution_strengthening

    The elastic interaction effects (i.e. size and modulus effects) dominate solid-solution strengthening for most crystalline materials. However, other effects, including charge and stacking fault effects, may also play a role. For ionic solids where electrostatic interaction dictates bond strength, charge effect is also important.
