This week I learned how to use a sight called maker studio.  It helps you make 3-d creations out of regular paper.  This week as I am just getting used to it, I decided to make a simple cube.

This app was very fun to use and I can’t wait to make more complicated projects with it.

This week we learned about trusses.  The project I did this week was to see what is stronger a surface with trusses versus a surface without.  I used toothpicks and grapes, and made two cubes.  One of my cubes had trusses and the other one did not. Next I put books on top to compare them.  The box without tresses just collapsed after I put one book down.  On the other hand, the box with trusses stood up after I put one book down. This proves that trusses make things less brittle and stronger.

This week I learned about I beams. For my weekly project I had to compare a cardboard I beam, to a bunch of cardboard strips taped together. Both of the beams were made out of the same material, and the same amount of that material.

When I put a water bottle, and one block, on top of my beam that was a bunch of cardboard stuck together, here’s what it looked like.

You can see how it is bending, which means that this design is brittle. However, when I put an I Beam to the test here’s what it looked like.

This been is very ductile  compared to the other one, because it is not bending with even more blocks on it.

Overall I learned that the I beam is the better than just a few strips taped together.
