Overinflating an air lift bag affects its contact with the surface how?

Overinflating an air lift bag decreases surface contact because an excessive amount of air in the bag makes it rigid and causes it to lose the ability to conform to the contours of the surface beneath it. When the bag is overinflated, it can result in a smaller area of the bag being in contact with the ground, which diminishes stability and effectiveness. Proper inflation is crucial for ensuring that the bag can distribute force evenly and maintain adequate contact with the surface, allowing it to perform effectively during a rescue operation. When the contact area is reduced, it can complicate the lifting process and potentially lead to failure in lifting or stabilizing the load properly.
