What Is the Strongest Shape?

CSEF · 2011 Applied Mechanics & Structures

Vivian N. Nedeltchev · Mountain View Junior High School, Beaumont, Riverside County

Overview

Objectives/Goals The objective of my project was to determine which 3-dimentional shape best withstood Static and dynamic forces. Methods/Materials I made four simple experiments to test the resistance to static and dynamic forces. I constructed 12 different shapes of equal area using twenty-four popsicle sticks and the same amount of glue. Each shape was tested with four experiments fifteen times. In the first two experiments I determined the resistance to static force; one testing piont force, one testing the holding force. The results were measured in Newtons. In the second two experiments I determined the dynamic force. In one of my tests I found the force it takes to break each shape, and the other test I found the lateral force. The results were measured in Joules. Results After I took the mean of each experiment I found the "A" shape had the most resistance to static and dynamic forces. The "A" shape is the stongest. Conclusions/Discussion While the results did not support my hypothesis I obtained my objective, to determine which 3-Dimentional shape best withstood static and dinamic forces. My projecthelps to find a more durable more earthquake resistant building.

Summary statement

My project determines which shape best withstoods static and dynamic forces with four different experiments which I repeated fifteen times, with twelve different shapes each constucted of 24 popsicle sticks and the same amount of glue&area.
