When a load is lifted by a crane, the center of gravity of the load does indeed adjust under the hook, particularly based on the load's configuration and how the weight is distributed. As the load is lifted, the center of gravity moves upwards, because the entire weight of the load is now being suspended directly by the crane rather than being in contact with the ground. This movement can also cause changes in the load dynamics if the load has various components or if there’s any shifting of the load during the hoisting process.

It’s important to note that the behavior of the center of gravity is not static; it responds to the forces acting on it and can shift depending on how the load interacts with the lifting mechanism and the environment. Hence, stating that the center of gravity adjusts under the crane hook when the load is lifted is correct and reflects an understanding of basic load dynamics in lifting operations.
