Which of the following best describes static analysis?

Static analysis is defined as the evaluation of a system or structure under loads that do not change over time, focusing primarily on equilibrium conditions. It investigates how forces, moments, and other physical constraints act on a structure when it is at rest or in a steady state. In this context, the analysis does not consider the effects of time-dependent loads such as those that vary with time or dynamic forces which would involve changes in motion or velocity.

Static analysis often employs methods like equilibrium of forces and moments and typically assumes that the material properties and loading conditions remain constant during the analysis period. This characteristic makes it essential for understanding how a structure can support certain loads safely while not experiencing time-varying forces or negative effects from dynamic behaviors like vibrations. Therefore, those aspects that focus on time-dependent effects or stochastic modeling, which incorporates randomness and variability into load effects, fall outside the scope of static analysis.
