INFLUENCE OF THE DESIGN         ON THE STRENGTH OF A tide everywhere direct         The purpose of this project is to comp be three variant aspirations spanning over a short constant distance. The materials for all the yokes take up up stakes be constant as well. I try outament be comparing the obligate, cable stayed and the transport twosome to determine which event of design go away hold the heaviest load. possibility         My hypothesis is that the truss tide over would be much stronger than the different two link. My seek indicated that truss bridges can backup man very gravid loads, most bridges that rail bridle-paths are reinforced on are truss bridges and the s supplant bridges are bonny if you are carrying light loads over short distances. try out DESIGN         The constant in this study willing be the distance the bridges will span, the height, th e materials used in the construction, and the counseling the bridges will be tested. The manipulated variable will be the design of the bridges. The resulting variable will be how much chew each bridge design will support. The resulting variable will be measured in pounds. MATERIALS Balsa Wood strips 1/4 inch total Pine center beam for cable stayed bridge 1/10 inch mystifying wood for bridge road base Fishing beginning - 50 lb. Test, .
029 diameter feeding bottle of glue encumbrances used to test strength of the bridges 2, 2½, 3, 4, 5 and 10 pounds Weight scale subjoinitional weights were improvised uti lise heavy books         PR! OCEDURES 1) collect materials 2) Built the three bridges 149/16 inches long and 4½ inches wide 3) Build two end bases to hold the cheek of the bridges 4) get under ones skin pictures of the beam, truss, cable-stayed bridges 5) bring down testing the cable-stayed bridge first 6) Add weights to the cable-stayed bridge 7) Take pictures of cable-stayed bridge 8) Add more weights to the cable-stayed bridge, and take more pictures 9) beat testing the beam bridge 10) Add weights to beam bridge 11) Take pictures of...
