__COURSE CONTENT__**Student Learning Outcomes:**

Upon completion of the course, students will be able to:

1. Apply Newton's 1st and 3rd laws to the force analysis of rigid bodies in static equilibrium.

2. Use scientific calculators to perform vector operations and solve systems of equations.

3. Use spreadsheets to analyze statics problems and display results to the standards of an engineering analysis report.

**Objectives:**

Upon completion of the course, students will be able to:

1. Apply a systematic algorithm to the analysis of statics problems.

2. Convert between force and position vectors and between Cartesian and spherical coordinate systems using a scientific calculator.

3. Apply both two and three dimensional vector equations for point equilibrium to solve for the tension or compression in supporting structures.

4. Compute the moment of a force about a point or an axis using cross product, dot product, and mixed triple product.

5. Apply moments and couples to determine equivalent force/moment systems on rigid bodies.

6. Develop vector equations of rigid body equilibrium and solve for the unknown reactions in both two and three dimensions.

7. Analyze trusses, frames, and machines using the principles of Newton's 1st and 3rd laws.

8. Construct shear and bending diagrams given load diagrams to describe the internal forces in beams.

9. Prepare engineering analysis reports with charts, tables, graphics, and proper documentation using spreadsheets.

Optional Objectives:

10. Apply statics principles to the analysis of dry friction statics problems.

11. Apply statics principles to the analysis of hydrostatic pressure problems.
