Unit 4.1: Statics

In Lesson 4.1, students explore various aspects of static structures and apply mathematical approaches to solve structural problems. They begin the lesson by applying an engineering design process to design and test a cantilever beam. Students then compare materials and their properties that impact beam deflection; they also use 3-D modeling software to analyze and investigate factors that impact beam deflection and solve an engineering design problem. Students analyze and solve systems through the use of free body diagrams, force vectors, moment calculations, and method of joints. They will also explore internal forces in materials and the relationship between stress and strain. Students culminate their understanding to design their own bridge truss to support a given load at the lowest cost.

Classroom Activities

1. Devotional/Prayer
2. Activity 4.1.5 Tensile Testing
   • For your graphs, use the manual for option with the curve fit.  Then add annotations for the proportional limit, yield point, and the ultimate tensile strength points. Each graph should be on a separate page in your engineering notebook.

Homework

• Keep Engineering notebook up to date
