When is the pressure of the man on the ground more – lying position or standing

Wittaler [7]

Hi,

The man on the ground in standing position has more pressure. This is because when he stands, only his legs are in contact with the ground. While lying, his body is more in contact with the ground, therefore, he exerts less pressure.

To the point, a man standing position on the ground had more pressure.

More is the area of contact, less is the pressure efforted.

Thank you...
