Course Description:

An introductory course in applied mechanics. Forces, moments, couples, and resultants. Vector algebra. Construction of free body diagrams. Equilibrium in 2- and 3-dimensions. Analysis of frames, machines, trusses and beams. Distributed forces. Friction.

Course Prerequisites:

Physics 1, Mathematics 3B.

Course Objectives:

Learn vector algebra and the representation of vectors and their components, analytically and graphically, including representation of forces, moments, and couples as vectors in two- and three-dimensions.

Develop capacity for visualizing physical configurations and learn how trusses, frames, machines, and beams are modeled in order to analyze relevant external and internal forces.

Learn to isolate a body or a member of a frame or machine and apply all forces acting on the body (i.e. construct free body diagrams).

By conducting analyses of forces acting on frames, machines, trusses, and beams, learn how these entities support and transmit loads.

Develop a foundation for more advanced beam theory; i.e., learn to construct shear and bending moment diagrams for beams loaded and supported in various ways.

Learn to incorporate and analyze friction in statics problems.

Develop capacity for logical, orderly, step-by-step methods of analysis and clear communication of results.

Become closer to being an engineer.

Topics Covered:

1. Vectors & Forces
2. Moments & Couples
3. Specialized Force Systems
4. Resultants
5. Free Body Diagrams
6. Equilibrium Conditions in 2- and 3- Dimensions
7. Plane Trusses
8. Frames & Machines
9. Centroids
10. Beams
11. Friction

Credit Units of Class/Laboratory Schedule:

3 units of lecture, 2.5 hr/week
1 unit of recitation section, 1 hr/week

Course Assignments:

Two (2) midterm quizzes
One (1) final exam
Weekly homework assignments

Professional Component:

4 units engineering topics

Relationship to Program Objectives:

1. Prepares students to succeed in the upper division lab and theory courses (in particular, strength of materials and dynamics), which in turn prepares students to be successful mechanical engineers and/or competitive graduate students.
       
2. Strengthens the mathematics background (in particular vector algebra) of the students.

Assignment of Grades:

The assignment of grades will be based on a point system, wherein 1200 is the maximum number of points that a student may earn. Points may be earned as follows:

The “Bonus” will be calculated as follows:
[(Your final exam score)/250] x (Your homework score)
   
Final course grades may be based on “a curve,” although any student earning 900 or more points will be assured an A+. Likewise, grades of A, B, or C will be assured, based on minimum scores of 800, 700, or 600, respectively.
