Most curricular materials in TeachEngineering are hierarchically organized; i.e., most hands-on activities are part of lessons, lessons are grouped into multiday curricular units and these again are bundled into subject areas. Some activities or lessons, however, were developed to stand alone, and hence, they might not conform to this strict hierarchy.

Mathematics in Construction . Introduction: In the real world of building construction there are many rich problems which can be used to build sense making and reasoning skills for students. The website "PBS for Teachers" offers ready to use lessons based on NTCM standards as an example.

The designer should have first seen and studied many bridges in the course of a long learning process. He should know what type of beam may be suitable in the available conditions, either a beam bridge an arch bridge or a suspended one. He should also know the influence of foundation conditions on the choice of spans and structural systems etc. hence, the designer

2 Fundamentals of Algebra, Geometry, and Trigonometry (Self-Study) Course Overview Introduction Math plays a very large role in the design and construction of highways and bridges. Although many math problems can be solved with the help of a

In modern bridges, reasons of technical and economic feasibility oblige an extreme parceling of the construction process, with the consequent need to revise, with respect to the past, both design concepts as well as the theoretical apparatus of analysis that governs it.

Linking of mathematics to construction and engineering There is a wide range of mathematical topics used in construction and engineering. Constructions takes the mathematical description of the word construction, exploring mathematical constructions and scale diagrams in different contexts; skills which are vital when working with plans.

Architecture is much more than simple boxes. It incorporates bridges, curves and other complex shapes best defined by mathematical formulas. In addition to trigonometry, other mathematical components are used. These include calculus, algebra, probability and statistics and linear programming.

Building bridges is a great beginning project that allows students to build upon their math skills using basic trigonometry formulas while learning how forces act upon a structure. They also get to enjoy building and testing their bridges. Integrating math into technology education activities is important to enhance their value as

Calculating Bridge Length. In a bridge construction project, trigonometry is essential for determining just how long a bridge needs to be. A contractor might use right angle properties and tangents to determine how wide a river is, which directly determines the length of a bridge.

In bridge building a cantilever construction is employed for large spans in certain sites, especially for heavy loading; the classic type is the Forth Bridge, Scotland, composed of three cantilevers with two connecting suspended spans. Cantilever cranes are necessary when a considerable area has to be served, as in steel stockyards and ...
