Science Engineering Challenge

The Science Engineering project was about making a building out of spaghetti and blue tack over 60 cm tall and surviving a S wave and P wave earthquake for 10 seconds each, the other requirements were only materials supplied from the teacher are allowed, max 30 by 30 base, can fit a 5 by 5 cm piece of paper on top and costs less than 60 dollars,  it was a dollar per spaghetti piece and each piece was 25 cm long and  one gram of blue tack cost a dollar. This project helped us link real life examples to the spaghetti building by looking at how engineers make buildings more earthquake proof and what shapes they make the building to withstand the earthquake. We then found at cross bracing and reinforcement is one of the most effective ways to survive S waves and P waves. Reinforcement is a major part of making the building more earthquake resistant because it constricts the amount the building moves when an earthquake occurs.

Building using cross bracing

Over time and through research of how engineers make buildings more earthquake proof we changed our designed to make the building more earthquake proof by adding cross bracing in the 2nd attempt to make a building instead of having having spaghetti strains from the ground supporting weak points in the first round like pillars. In the second round we added reinforcement in the middle of the intersection of the cross bracing instead of just having cross bracing, this made the building more sturdier because the cross bracing was even more effective since it couldn’t move much.

One change I would make to the Engineering process to improve the outcome of the building would be instead of having the first round without any research and completing it with prior knowledge of buildings we would research how we can make a earthquake resistant proof building and use the methods we research. Then we would build another time and use different techniques we used were good and which were bad then we would build one last time and combine all the techniques that worked the best, this would allow us to have the most efficient building we could build.
