Activity 2.1.3 Free Body Diagrams
In this activity you will practice creating free body diagrams (FBD) in order to evaluate all of the forces interacting with those objects.

Activity 2.1.4 Calculating Force Vectors
In this activity you will calculate force vectors.

Activity 2.1.5 Calculating Moments
You will explore firsthand the relationship between forces and distances as they are applied to a rigid object. In this activity you will be required to keep a meter stick level as varying moments are applied to the meter stick. For the purpose of this activity, the weight of the meter stick is not considered. You can either balance the mass on the stick or hang the mass from a string.

Activity 2.1.6 Step-by-Step Truss Calculations
In this activity you will calculate reaction and member forces for the truss system illustrated below. It is essential to follow each step within the procedure to ensure proper calculations and free body diagrams.
Activity 2.1.7 Calculating Truss Forces
In this activity you will make changes to given trusses to make them statically determinate. You will then solve for the outside forces and forces at each pinned connection of trusses.

Conclusion
1. How does design affect material selection?
1. How does design affect material selection?
- Material selection is a step in the process of designing any physical object. In the context of product design, the main goal of material selection is to minimize cost while meeting product performance goals. Systematic selection of the best material for a given application begins with properties and costs of candidate materials.
- Product quality , Cost of the material and transportation or freight costs, relation to the stock markets and supply and demand formula, material durability and availability of spare parts .
- Mechanical and physical properties
Activity 2.3.1 Stress/Strain Calculations
You will learn about physical properties related to strengths of materials and apply this information to solve common engineering problems.
