Suppose for some reason you have to walk in bare feet across a short distance covered by broken glass. Would you want the pieces of glass to be large or small?

Question

Large. If the pieces are larger than my foot, my foot wouldn't have to touch the sharp sides and get cut.

Make sense?

but what about p=f/a?

joannablackwelder · Answer

That equation holds up my statement. When area is smaller and force is the same, pressure is larger.

anonymous · Answer

wouldnt you want less pressure? So there is no penetration

joannablackwelder · Answer

Yes, you want less pressure, which means you need larger area.

anonymous · Answer
