Discussion Overview

The discussion revolves around designing and constructing a stable tower using only paper and tape, specifically aimed at supporting a weight of at least three textbooks. The project has constraints regarding the materials and structural requirements, including height and stability.

Discussion Character

  • Homework-related
  • Exploratory
  • Technical explanation

Main Points Raised

  • One participant requests clarification on the approximate weight of the textbooks, which is stated to be about 1.5 pounds each, with a goal of supporting over 27 pounds total.
  • Suggestions include cutting the paper into pieces and forming cylinders, which are then connected with tape to create a stable structure.
  • Another participant proposes a "zig-zag" folding technique for the cylinders to enhance their resistance to compression, although this may reduce their radius.
  • There is a discussion about the necessity of connecting all parts of the structure to ensure stability.
  • A participant shares an example of using a bank note to illustrate a folding technique that could be adapted for the paper tower project.
  • One participant mentions a similar project from a class called "intro to engineering," highlighting the importance of brainstorming and design within class constraints.

Areas of Agreement / Disagreement

Participants express various ideas and approaches to building the tower, but there is no consensus on a single method. Multiple competing views on the design and construction techniques remain present throughout the discussion.

Contextual Notes

Participants discuss various folding and structural techniques without resolving the effectiveness of each method. There are assumptions regarding the properties of paper and the expected load that are not explicitly stated.

I have to build a tower in class that supports at least three textbooks.

Materials
2 pieces of regular printer paper
12 inches of masking tape

Specifics
Must be at least 4" tall
Cannot crumple

I've been working all day trying to figure it out...any help would be welcomed
 
Physics news on Phys.org
Anyone?
 
Give an approximate weight for these textbooks.
 
about 1.5 pounds...we have to have at least three, but our main goal is to have over 27
 
any suggestions
 
Are you allowed multiple folds?
 
Ok I've just worked it out. Cut each A4 sheet of paper into 4 pieces. Then turn them into cylinders keeping them together with the tape. Then simply space these 8 cyinders out with gaps in the middle, and the books should hold. If you don't understand that just say and ill try explain better.
 
yes...just forgot something...they all have to be connected
 
Ok then connect them.

Another possibility is to fold the cylinders at "zig-zag"; this make them more resistant to compression (but reduces their radius). I sometimes play with bank notes this way to sustain glassess.

Ok, so I would go for a cylinder shape, wether zig zagged or not, I think this is the way to go. Good luck.

lightarrow, can you show me an example?

With a bank note: fold the short side of it about 8 mm, then fold the successive 8 mm in the opposite way ecc. At the end you have a kind of "folding door". Then you connect the two short ends of the bank note and you have a kind of "toothed cylinder" one base of which is put horizontallly on a table; then you slowly put an object (a glass for example) trying to find its correct horizontal position on the folded bank note with slight corrections (or it will fall down). It requires some practice. I usually use a 10 € bank note.

What class is this for?

I had a similar project in a class called "intro to engineering" It was team based and we had to build a load bearing structure out of balsa wood. However, we had to do our brainstorming and final concept design in class to prevent outside help.

In addition to what I wrote, I think that "toothed cylinder" construction should be stabilized putting it between two normal cylinders of paper, so that it cannot "open" or "close" when you put the books on it.
>Good work.
Let me know if you succeeded and how.
