Kelsay and Elisha's Structure Pic

  1. 1) Is your building more or less stable when the mass is placed on higher floors?

    I think mine and Elisha's structure was not more stable at the top when we put the mass on because at the bottom floor it is closer to the ground and the ground made it more stable a the bottom.

    2) Describe how the centre of gravity moves as the 100-g mass moves up each floor.

    The center of gravity moves as the 100-g mass goes up each floor because if you just kept it in the middle, at the top it would go on a slant or fall down. But the lower you go the less it goes to a slant because the ground is making it more sturdier.

    3) After you moved the 100-g mass closer to the edge of each floor rather than in the middle what differences did you notice in the stability of the building.

    I noticed that the closer we had the mass to the edge the more it started to go on a slant.

    4) What changes could you make to your design that would make the building more stable when the centre of mass is high or near the edge of a floor?

    To make our structure more stable I think we could put straws on each corner, side and the middle.

  2. I think that Emily and Ally's structure was more stable than everyone else's because it was able to hold the mass in the middle and the edge without falling. I think when they put the card board on the bottom of the straws made it more secure.

  3. I thought that Kelsay and I's structure was not more stable when we put the mass on the higher floors because the bottom floor had more tape and more support because it was closer to the ground.

    The center of gravity changes once you go up each floor because as we put the mass on the higher floors I found that our structer started to flop and fall over because we did not have enough support.

    Once the 100 G mass got closer to the edge of our structure, I found that our structure had started to fall over because the center of gravity was in the middle not on the edge. I think that the center of gravity was closer to the edge because our structer was not very stabe and under the three floors we had not support so the whole thing started to fall over.

    Some changes that Kelsay and I could make to our structure to make it more stable when is use more tap and maybe put some straws underneath each floor to make the floors stay straigt and not floop.

  4. You are right on with your observations; your building started to topple when the mass was added higher up to your building because you didnt have the stability there to support it.
    Well answered!
