Truss Bridge Physics 141 Robin Hoffmeister There is many reason that we need bridges in every day of our life‚ from sufficient means to pass over a roadway‚ waterway‚ railway‚ or other structure. You don’t even think about them because it takes no effort to get over them and they are just there for your use. So if you don’t think of them for everyday use I highly doubt that you would think of the physics that is involved in putting one together or the kind of force the bridge can actually

Bridge Project Questions 1- History of Bridges In the beginning bridges were very simple structures that were built from easily accessible natural resources- wooden logs‚ stone and dirt. Because of that‚ they had ability only to span very close distances‚ and their structural integrity was not high because mortar was not yet invented and rain slowly but constantly dissolved dirt fillings of the bridge. Revolution in the bridge construction came in Ancient Rome whose engineers found that

trusses used in bridge design? Include the importance of triangular shapes in truss design. A truss is a formation produced by triangular components. The triangular units forming the truss are slim and straight in form. The truss bridges consist of a grouping of triangles. Trusses are used in bridge design to form a series of strong supports using triangles‚ and have the forces of tension and compression acting on them. The importance of triangular shapes in truss design is that when a force is applied

Ambrose Bierce’s‚ “An Occurrence at Owl Creek Bridge”‚ is the story of a want-to-be hero. The main character‚ Peyton Farquhar‚ cannot participate in the war‚ and has to stick to just being a farmer. Bierce puts a spin on what it is to be a hero in this story‚ and what happens to them. In his story through the eyes of Farquahr‚ one must be a soldier‚ do something spectacular‚ and then make away back home to the soldiers family‚ to be a hero. These are the three parts of what it means to be a hero;

Popsicle-Stick Bridge The goal: to build the strongest possible bridge to take a matchbox car‚ using wooden popsicle sticks. Constraints: The bridge must span a 55cm gap No more than 100 popsicle sticks may be used The sticks may not be cut Only white glue may be used Construction paper may be used for the deck only The test load is applied to a 4cm-wide section at the top of the arch. The test jig looks like this: (Well-built bridges can support over

CAREY FOSTER BRIDGE Introduction The Carey Foster bridge is an electrical circuit that can be used to measure very small resistances. It works on the same principle as Wheatstone’s bridge‚ which consists of four resistances‚ P‚ Q‚ R and S that are connected to each other as shown in the circuit diagram in Figure 1. In this circuit‚ G is a galvanometer‚ E is a lead accumulator‚ and K1 and K are the galvanometer key and the battery key respectively. If the values of the resistances are adjusted so

Spaghetti Bridge Abstract For this assignment our task was to build as a group a spaghetti bridge with the objective of carrying the most weight as possible using only spaghetti and hot glue‚ meeting the specifications. The bridges will be loaded until they fall. After testing to destruction‚ the bridges loading capacity was 14.4kg‚ with an initial mas of 0.840kg. This gave a weight to strength ratio of 17.1 putting the group at 4th/8th position in class. From this it was learned the
