In a bridge construction project, trigonometry is essential for determining just how long a bridge needs to be. This shows a way that math is used in architecture. The beam or truss bridge is, in effect, a pair of girders supporting a deck spanning the gap between two piers. Building bridges requires knowledge of parabolas and trig. There is a pressing need to improve academic performance, proficiency on the CAPT test, and completing high school. Geometry of Bridge Construction The four kinds of bridges and some combinations A. We use math in roads and vehicles as well. Conclusion Explain how it will help Describe the next steps Refer back to the pros and cons what are the different types of bridges how does math go into bridge building there are five main types of bridges they are Beam bridge, Arch bridge, Cantilever bridge, Cable-stayed Travel is made easier by math as we are able to make bridges across water. Calculating Bridge Length. Such a beam has to withstand both compression in its upper parts and tension in its lower parts. Travel in general requires a lot of math. This unit on the use of math and science involved in building/engineering bridges is relevant to the importance of efficiency and safety of the bridges we use to cross our water ways, specifically one close to home: The Brent Spence Bridge. Figure 4: Steel Truss Road Bridge Figure 5: Space Frame Roof Structure It should be noted that this type of triangulated structure is used not only in bridge construction … Consequently, the development and use of a curriculum that focuses on the practical application of the basic mathematical concepts should be helpful in addressing the student's deficiencies. Given the level of mathematics that is taught at the eighth grade level, the mathematical focus on the topic of bridges will be on proportions. The development and use of a curriculum that focuses on the application of math and problem solving of the real life problems in the building of bridges should help inspire and motivate learning. A contractor might use right angle properties and tangents to determine how wide a river is, which directly determines the length of a bridge.

Building Bridges with Math + Engineering Posted 02/20/2018 by Kelly Kutach @TIKellyK This week is Engineers Week, the perfect time for math and science teachers to hug-it-out and work together to get students excited about engineering.
