Tyler and Devon's Structure

4 comments:

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

    My building is less stable when it is placed on the higher floors because when the weight is placed on floor surfaces its closer to the gravity pull so the building wont pull down or fall over.

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

    My center of gravity did not move it seemed like.

    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.

    The building was a lot less stable because all the weight was in one place ferthist away from the center of gravity.

    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?

    I could change how long the straws were because i noticed the shorter the straws were the more stable it was. So have the shortest straws at the top

    Our building didn't really have a big change when it was placed on higher floors.

    2) Describe how the centre of gravity moves as the 100-g mass moves up each floor.
    The center of gravity might change because our structure was probably not totally straight.

    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.
    The stability of the structure got worse because the weight was not on the center of gravity or close to it with made it tilt on its edge.

    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?
    You could make sure you have a very wide base so it has a better center of gravity and you could make the higher floors smaller so the bottom has more weight than the top. Which will make it more stable.

  4. Tyler,

    Interesting observation for #4 - I didn't notice this.

    Devon,
    You are right on with your answer for question #4.

    Ms. F
