When a stacker carries a full load with its center of gravity positioned at the back, what is the effect on stability?

When a stacker carries a full load with its center of gravity positioned at the back, it primarily affects the longitudinal stability of the vehicle. Longitudinal stability refers to the stacker's ability to remain upright and balanced in the forward-backward direction. When the load's center of gravity shifts towards the back of the stacker, it can increase the stacker's stability in this direction, enhancing its ability to support and handle the load without tipping over.

However, it's important to consider that while having the load's center of gravity at the back may improve longitudinal stability, it does not necessarily enhance lateral stability, which is the stacker's ability to remain balanced in the side-to-side direction. A load that is positioned improperly can lead to potential risks, such as tipping during turns or on uneven surfaces.

This context underlines why the answer emphasizes longitudinal stability, as the stability dynamics change based on the load's center of gravity.
