# The Constructed World

The **Constructed World **provides opportunities for students to connect mathematics to building and construction and to engineering designs.

- Structural engineers use a variety of mathematical concepts to test the strength and rigidity of construction materials, such as those used in different types of beams.
- Aeronautical engineers likewise need mathematics to design and test the effectiveness different types of wings for aircraft
- Mechanical engineers use mathematics to describe and analyze the motion of parts of a machine.

Exploring problems from the constructed world allows students to study mathematical relationships, to see the interplay of mathematical ideas, and to appreciate the relevance of mathematics in today’s world. Appropriately chosen activities and problems from the constructed world can help students develop better understandings of mathematical concepts and perhaps encourage more students to enter engineering fields.
