Which load type can be described as exerted by a stationary force, such as parked equipment?

The correct choice for describing a load exerted by a stationary force, such as parked equipment, is the static load. A static load refers to a constant, stable force applied to a structure or component that does not change over time. In contexts such as construction or engineering, this type of load represents forces that are applied gradually and remain at a relatively constant level, making it essential to consider during the design phase to ensure safety and stability.

Dynamic loads, on the other hand, involve forces that change over time, such as moving vehicles or machinery in operation, and are often associated with impacts and varying weights. Differential loads relate to forces that are unevenly distributed across an area, while impact loads are characterized by forces applied suddenly, as in collisions. Since the question specifies a stationary force, the characteristics of static load align perfectly with the scenario of parked equipment, justifying why this is the correct answer.
