Homework Statement



Let's say there are two objects, Object A and Object B...

-Object A weighs a little less than Object B
-Object A has significantly more surface area than Object B
-Both Object A and Object B are supported by identical structures

What I want to know, is which object creates more force (or is it pressure?) on the structure? If the weights are given, how can I calculate this so I know which one applies more force?

Homework Equations





The Attempt at a Solution



This is not a homework assignment. Just seeking the knowledge.

You must distinguish between the force exerted, which will equal the weight of the object, with the pressure created. Pressure = force per unit area.
