what is static loading

Static loading refers to a mechanical force that is applied slowly to an object or assembly, and it remains constant over time. Static loads are used to determine the maximum loads that can be withstood by structures such as bridges or floors in tower blocks, and to work out the strength of different types of material. Static loads are different from dynamic loads, where forces are applied rapidly and can change. Examples of static loads include the weight of a building bearing down on the ground or a car parked on a road. Static loads can be considered constant throughout the life of a structure, while dynamic loads arise in a sudden way, and their characteristics vary every time they occur, even within the same occurrence. The deformation of structures under static loads reaches its zenith when the static force is at its maximum. The difference between static load and dynamic load is that static load is the maximum thrust load that should be applied to a non-moving screw or actuator while it is fixed or stationary, while dynamic load is the maximum recommended thrust load which should be applied to the screw or actuator while in motion.
