# Newtons third law and unbreakability [closed]

We all know Newton's third law.

But then why this law doesn't work when we place a 1000KG heavy container on a small weak table. The table will break. Pressure is exerted on table by container, and table exerts force on the ground.

Similarly a heavy pillar will break a weak wall while leaning upon it.

• I don't see how you get from the table breaking to assuming that Newton's third law is invalid. – David Z Dec 14 '14 at 14:03
• I am asking this because when body rests on table we say it is because of normal reaction which is equal and opposite. But what if body is very heavy ? – AnjumSKhan Dec 14 '14 at 14:05
• I would appreciate if you can explain the answer instead of down voting. – AnjumSKhan Dec 14 '14 at 14:05
• I would appreciate if you ask a question. – pfnuesel Dec 14 '14 at 14:10
• Equal and opposite forces do not imply immobility. You can have motion because the forces are acting on different bodies. See related posts on the side ---> – John Alexiou Dec 14 '14 at 15:33
