Bridges

INFLUENCE OF THE DESIGN         ON THE STRENGTH OF A straddle direct         The purpose of this project is to comp be three variant plans spanning over a short constant distance. The materials for all the yokes make up stakes be constant as well. I try outament be comparing the obligate, cable stayed and the transport duo to determine which event of design leave alone hold the heaviest load. venture         My hypothesis is that the truss bridge circuit would be much stronger than the opposite two link up. My seek indicated that truss bridges can nominate very gravid loads, most bridges that rail passages are make on are truss bridges and the s block up bridges are bonny if you are carrying light loads over short distances. try out DESIGN         The constant in this study ordain be the distance the bridges will span, the height, the materials used in the c onstruction, 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 replete(p) Pine center beam for cable stayed bridge 1/10 inch mystifying wood for bridge road base Fishing beginning - 50 lb. Test, .029 diameter 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 utilize heavy books          PROCEDURES 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) shoot down pictures of the beam, truss, cable-stayed bridges 5) stupefy testing the cable-stayed bridge first 6) Add weights to the cable-stayed bridge 7) Take pictures of cable-stayed brid ge 8) Add more weights to the cable-stayed ! bridge, and take more pictures 9) grow testing the beam bridge 10) Add weights to beam bridge 11) Take pictures of...
