compression

Examples of compression in the following topics:

• Dry Media

  • Compressed charcoal is charcoal powder mixed with a gum binder compressed into round or square sticks.
  • Compressed charcoal is used in charcoal pencils.
  • Conté, also known as Conté sticks or Conté crayons, are a drawing medium composed of compressed powdered graphite or charcoal mixed with a wax or clay base, square in cross-section.

• Roman Architecture under the Republic

  • An arch is a pure compression form.
  • It can span a large area by resolving forces into compressive stresses (pushing downward) and, in turn eliminating tensile stresses (pushing outward).
  • The dotted line extending downward from the keystone (1) shows the strength of the arch directing compressive stresses (represented by the downward-pointing arrows outside the arch) safely to the ground.

• Post-and-Lintel Construction

  • The first is where the lintel meets the post, which compresses the columns.

• Arches, Vaults, and Domes

  • An arch can span a large area by resolving forces into compressive stresses, eliminating tensile stresses in turn.
  • Parabolic arches employ the principle that when weight is uniformly applied to an arch, the internal compression resulting from that weight will follow a parabolic profile.

• Reinforced Concrete Construction

  • If a material with high strength in tension, such as steel, is placed within the concrete, the composite material (reinforced concrete) resists not only compression, but also bending and other direct tensile actions.
  • A reinforced concrete section where the concrete resists the compression, and steel resists the tension, can be made into almost any shape and size for the construction industry, as exhibited by the Philips Pavilion .

• Stonework on Easter Island

  • Almost all moai (roughly 95%) were carved out of distinctive, compressed, and easily worked solidified volcanic ash or tuff found at a single site inside the extinct volcano Rano Raraku.

• Cast-Iron Architecture

  • It is strong in compression, but weak in tension and bending.

• Michelangelo

  • Above them the huge cornice ripples in a continuous band, giving the appearance of keeping the whole building in a state of compression.

• Watercolor

  • Hot pressed papers are cold pressed sheets that are passed through heated, compressing metal cylinders, which flattens almost all the texture in the sheets until they are incredibly smooth.
