Lets say you have a completely rigid blue-colored object shaped as shown below. The object had one wide protrusion on one side and four smaller protrusions on the other side. Everything is completely symmetric so that the weight would be evenly distributed. Lets say you press with 12 N of force on the top surface distributing the force completely evenly over this top surface. What would the individual force be at each of the four protrusions. Would it be (12/4)=3 N? Or would it have to be the same as the force applied to the top surface, namely 12 N?
