SUMMARY
The pressure applied to the ground by a 52 kg man standing on square stilts measuring 0.06 m on each edge is calculated using the formula p = F/A, resulting in a pressure of 207,100 Pa. The total force is derived from the man's weight (mg), while the total area is calculated based on the dimensions of the stilts. The discussion emphasizes that pressure is an intensive variable and does not accumulate with multiple stilts, as forces do. The weight of the stilts is generally considered negligible in this calculation.
