The Longest ,Lightest And Strongest Popsicle Stick Bridge
Transcript of The Longest ,Lightest And Strongest Popsicle Stick Bridge
The accomplishment was that my bridge didn't break when I stood on it and I also finished my bridge on time and attached it with Samuel's. Stringers:
Use 4.5" long x 0.38" (inch) solid wooden popsicle sticks . For the top stringer you'll need 7 sticks, 3 in the front and 4 at the back. For the bottom stringer you'll need 5 sticks, 2 in the front and 3 in the back and glue them together. Truss : To make a truss you'll have to add popsicle sticks ,one on each side to add the top and bottom stringers, which should make a trapezoid shape each stick should be 70 degrees from the stringers. After that, you add 7 more Popsicle sticks in front and 7 on the back to make triangle shapes. Each stick on the triangle should be 1/4 of an inch apart. Design Process Continued : Individual Bridge: To make a Individual Bridge you need to add tie members, stringers, and trusses. To add support you use diagonals and create "x"s. These add support because these create the strongest shape; a triangle. Compression Tension Compression Tension Tension Compression My Bridge! THE END!
and any other information will be included in my design process log. 70 o : 1/4 of an inch not my truss, it's not perfect. The tie members all have to be alined. Tie Members
