If I have something that is can take 130 pounds per square inch does that mean that it takes that much weight it can hold before it breaks? So if something is spread over 4 inches does that mean it can hold up 520 pounds?

Have you ever had a cat fall asleep on your chest? It’s cozy, because you have 20 lbs of cat spread out over the entire surface of the cat – let’s just say 20 sq inches, so that’s 1 lb/sqin
However, when that cat wakes up, stands up and stretches, you will think your chest is going to implode. Now 20 lbs of cat is being supported by 4 tiny paws – let’s say each paw (cats stand on their tippy toes) is about 1/2 in sq. So that is 20 lbs of cat now focused on just 2 sq in of surface area. 10 lb/sqin
