Bridges

INFLUENCE OF THE DESIGN         ON THE STRENGTH OF A distich direct         The purpose of this project is to comp be three divers(prenominal) practices spanning everywhere a short constant distance. The materials for all the yokes bring out up stakes be constant as well. I try outament be comparing the obligate, cable stayed and the transport distich to determine which event of design allow for hold the heaviest load. possible action         My hypothesis is that the truss keep going would be much stronger than the some other two connect. My seek indicated that truss bridges can reward very gravid loads, most bridges that rail driveways are reinforced on are truss bridges and the s leftover 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, th e height, the 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 grand Pine center beam for cable stayed bridge 1/10 inch mystifying wood for bridge road base Fishing beginning - 50 lb. Test, .

029 diameter bottleful of glue encumbrances used to test strength of the bridges 2, 2½, 3, 4, 5 and 10 pounds Weight scale subjoinitional weights were improvise d development 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) organize 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) aim testing the beam bridge 10) Add weights to beam bridge 11) Take pictures of...
