How does a sharp object break through other objects without initial force(unlike, for example, bullets etc)
In: Technology
Take a rubber mallet and give yourself a light tap on the hand with it. It hurts a little bit, right? Now take an ordinary hammer with the same weight, and give yourself a light tap on the hand with it. It hurts more. Why? Because although the force being applied is the same, the hammer’s head applies the force over a smaller area.
That’s basically what sharp blades do. They apply force to an extremely small area. So small that the material just gives way under the extreme force.
