Discussion Questions: Pantheon Dome
Can you think of a dome in a public building, religious building, sports stadium or other structure near where you live? Describe the parts of the dome that are in tension and compression. How did the people who built this dome solve the problems of tension and compression? The narrator states that, "...compression makes the ring strong and stable." Why is this true? Explain the forces involved? The narrator explains that, "...about halfway down, the ring pushes out. This is called tension." Why does this happen? Can you explain the forces involved? The step rings solved a problem that the Pantheon Dome had. Can you find structures around you that required some additional feature to take care of a problem they had? Are there outward forces on the walls of our building, of the swings sets in the playground, and in other structures?
