Engineering Design Languages

Four different representations or languages to describe the bolt can be used to describe any mechanical object:

  • Semantic. The verbal or textual representation of the object—for example, the word bolt, or the sentence, “The shear stress on the bolt is the shear force divided by the stress area.”
  • Graphical. The drawings of the object—for example, scale representations such as solid models, orthogonal drawings, sketches, or artistic renderings.
  • Analytical. The equations, rules, or procedures representing the form or function of the object—for example, τ = F/A.
  • Physical. The hardware or a physical model of the object.
