Outside the factory, robots have been employed in bomb disposal, space explorationand many other fields. Robots are also sold for various residential applications, from recreation to engkneering applications. Structural analysis is the branch of mechanical engineering and also civil engineering devoted to examining why and how objects fail and to fix the objects and their performance. Structural failures occur in two general modes: static failure, and fatigue failure.

Static structural failure occurs when, upon being loaded having a force applied the object being analyzed either breaks or is deformed plasticallydepending on the criterion how to make apple green color failure. Fatigue failure occurs when an object fails after a number of repeated loading and unloading cycles. Fatigue failure occurs because of imperfections in the object: a microscopic crack on the surface of the object, for instance, will grow slightly with each cycle propagation until the crack is large enough to cause ultimate failure.

Failure is not simply defined as when a part breaks, however; it is defined as when a part does not operate as intended. Some systems, such as the perforated top sections of some plastic bags, are designed to break. If these systems do not break, failure analysis might be employed to determine the cause.
