Answer to Question #4340 in Mechanics | Relativity for Brent
I wasn't sure what category to ask this in, but this one seemed like the best bet. My question involves force and surface area.
Let's say there are two objects, Object A and Object B:
-Object A weighs a little less than Object B
-Object A has far more surface area than Object B
-Both Object A and Object B are being supported by identical structures
Which will have more force on the structure? How do I calculate the force (or would it be pressure?) that each object has on the structure?
Force acting onthe structure is pressure: P=F/S
where F is theweight of an object, S - the surface of an object that touches the structure. So Fa<Fb ; Sa>>SbPa=Fa/Sa; Pb=Fb/Sb
So A has lessforce on the struct. as its surface is bigger and force smaller.
