- Homework Statement
- To find the pressure difference between two points on the same surface

- Relevant Equations
- P=F/A

Hi guys, I am not doing homework, it is just suddenly brainstormed this question.

What if I place a very small mass like 10kg on the center of a concrete 10m*10m flat table supported by the ground, then how to measure the surface pressure acting on the center and right on the edge? Or the pressure difference between two particular points?

Pressure(center)=(10*9.8)/(?)

Pressure(edge)=(10*9.8)/(10*10)

It should be not correct, but how to measure the pressure at the particular point?
