I guess the pressure would reach equilibrium after the weight is stable, that is when points X and Y are stable. So, the answer should be A?

No, so it should only be very high pressure.

Yes, assume it is rigid. I thought there are the same pressure on the two points before, but it seems wrong after considering the force is acting like a point.

I get the point of the pressure of the contact point would be large as infinite, but could we tell the pressure difference between the contact point and the point away from it?

That is the tricky point, the weight is just like a point source, we could only have the information of dimension (the center to edge, the size of the table).

It is just very simple, we can imagine it is not a "table" but a square solid.

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...
