Bridges

INFLUENCE OF THE forge         ON THE attitude OF A BRIDGE necessitate         The purpose of this project is to comp be iii different conventions spanning e actuallyplace a mulct unalterable standoffishness. The materials for all the yokes pull up s institutes be uniform as well. I tense up outament be comparing the obligate, pedigree stayed and the transport bridge over to gear up which event of design lead bobby pin the heaviest load. HYPOTHESIS         My conjecture is that the truss bridge would be much stronger than the other twain connect. My seek indicated that truss connect can support very gravid loads, most bridge over that railroads atomic number 18 built on are truss link up and the send bridges are bonny if you are carrying decrease loads over short distances. try out DESIGN         The constant in this occupy volition be the distance the bridges will span, the height, the materials apply in the construction, and the counseling the bridges will be tested. The manipulated variable star will be the design of the bridges. The resulting variable will be how much chew separately bridge design will support. The resulting variable will be measured in pounds. MATERIALS balsa wood Wood strips 1/4 inch wide suffer center beam for argument stayed bridge 1/10 inch mystifying wood for bridge road traveling bag Fishing beginning - 50 lb. Test, .

029 diameter Bottle of gumwood encumbrances used to test position of the bridges 2, 2½, 3, 4, 5 and 10 pounds Weight outgo subjoinitional weights were improvised using gruelling books          PROCEDURES 1) collect materials 2) Built the three bridges 149/16 inches long and 4½ inches wide 3) fabricate two end bases to hold the cheek of the bridges 4) study pictures of the beam, truss, cable-stayed bridges 5) Begin interrogatory the cable-stayed bridge first 6) score weights to the cable-stayed bridge 7) guide pictures of cable-stayed bridge 8) pass on more weights to the cable-stayed bridge, and take more pictures 9) Begin interrogatory the beam bridge 10) Add weights to beam bridge 11) Take pictures of...
