Ar500 steel plate can stop rifle bullets. In my brain I’m thinking like “well if kevlar is stronger than steel, then slab of kevlar of the same size of an ar500 plate should stop rifle bullets too”. Clearly it doesn’t and I don’t understand why
In: Engineering
The issue is that you dont understand strength; strength is not a simple thing; kevlar has a higher tensile strength than steel but is weaker in other meaurements, ie its less hard.
Rope has excellent tensile strength (pull on it and it wont tear) but terrible resistance to bending (you can bend a piece of rope easily)
