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 4.1.7 Step-By-Step Truss Analysis Worksheet Answer Key
3. Test will be on 12/4
4. Continue Bridge Project
   • Should have an electronic documented bridge design in your engineering notebook. Should be to scale like 1/4":1". 
   • Make sure you document any changes you make.
   • Show your prototyping.
   • Expect it to be on the order of 10 plus pages.
   • All team members should be sharing the info. No excuse to say it was in another team members engineering notebook.
   • Testing of bridges will be on 12/8

Homework

• Keep Engineering notebook up to date
