| Review problems with Homework Set #5. |
| |
| Introduce the application of Conservation of Linear Momentum (COLM) to 2-D and 3-D |
| statics problems involving concurrent forces. |
| |
| Discuss the behavior of ropes, cables, wires, etc. These members experience either tension |
| or no force. |
| |
| Discuss generalities of 2-force members such as struts and links. The forces in these |
| members are aligned with the longitudinal axis of the member and can be either tension |
| or compression. However, these concepts cannot be proved until conservation of angular |
| momentum is introduced later in the course. |
| |
| Examples are presented in Worked Problem Set #6. |
| Skills/Objectives: |
| |
| Solution of COLM problems. |
| Assessment: |
| |
| Homework Set #6: Work problems 3-11, 12, 14, 20, 21, 23 and 26 (due on Day 7). |
| Resources: |
| |
| Reference #4, Glover Chapter 5 (pp. 105-124), Worked Problem Set #6. |
| Notes: |
| |
| The solution to each problem MUST include a units table, all necessary system diagrams, |
| all necessary conservation tables, and then the solution. |
| |
| Caution the students to avoid the form of the solutions presented in R/S Chapter 3. |
