While working on the bridge‚ I was asking how do congruent structures give strength to bridges in real life? I think congruent structures give strength to the bridge because triangles have their rigid shape and strength. Unlike a square‚ that can shift into a parallelogram when force is applied to one of its sides‚ an equilateral triangle’s sides and angles are fixed. For example‚ triangles have beam which are the rigid shapes that helps the abutments of the bridge. When triangles supports the abutments

The Tacoma Narrows Bridge was the third largest in the world in 1940. Unfortunately that wouldn’t last too long. On November 7th‚ 1940 only four months after being open it collapsed due to violent swaying and flexing. Some of the reasons for its collapse were that it was put in an area of Tacoma that was prone to high winds and the engineer used solid girders instead of open trusses to cut costs. Another issue that engineers later learned about was its lack of aerodynamics. With that said we will

What is a truss and how are 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

Advantages Truss bridges have many advantages that make it more useful for everyday use. The truss bridge is very economical to build and uses very few resources. It uses light materials and small loads of timber or whatever it is being made of. It is also one of the stronger bridges that can be built. The trusses on top of the bridge make it very strong because the triangle shape takes away much of the pressure and spreads the pressure to the triangles and takes it away from the road part of the

Have you ever crossed a bridge when driving around your city and thought about how it was constructed or how long did it take to be built or is this bridge really safe and will it ever fall down. Well‚ I certainly have and I know that I don’t want for a bridge to fall down whenever I am driving or walking across one. It was 6:05 pm‚ the rush hour in Minneapolis‚ Minnesota and the unimaginable at the I-35W bridge occurred. On August 1‚ 2007 the 1‚907 foot long bridge collapsed leaving dozens of cars

uncommon; approximately 12% of U.S. bridges are rated structurally deficient. T Steel truss bridges‚ like I-35W‚ were more frequently labeled structurally deficient; approximately 31% of the 465 steel truss bridges in the U.S. were listed as structurally deficient at the time of the collapse. Such bridges consist of straight beams of steel formed into triangular units (Figure 1). In large steel truss bridges‚ the ends of the beams are connected with riveted metal plates called gusset plates

with Godwin. This is the bridge a lot of people know King for because it was the first to connect the two states. The bridge crosses over the Chattahoochee River. At completion‚ the bridge reached approximately 900 feet long and was built in the Town truss mode. This earned Godwin and King reputations as master bridge builders. The flood of February and March 1841‚ destroyed a large portion of the bridge south of Columbus Georgia‚ and swept away almost all of the main city bridge in Columbus. Godwin
