A "C" grade indicates that a student has a marginal mastery of the objectives
of the courses. The grades above a "C" are used for those students who
have demonstrated some degree of superiority.
An "I" means the student was not able to complete the course by the
end of the term, but has satisfactorily complete a sufficient portion of
it and can be expected to finish without having to reenroll in it. See
page 30 of the University Catalog for more details.

Learner Objectives and Assessment Strategies


1. Students will understand
the relationships between metric and US units and have the ability to work
in both arenas. A foundation for problem solving techniques is developed
and students will be able to apply analytical skills in engineering statics,
the study of forces on objects at rest.

Demonstrate these principles in classroom exercises, homework problems, examinations, and final report based on applying knowledge to solve analytical problems. 
2. Demonstrate an understanding
of vectors and be able to express and resolve vectors in two and three
dimensions.

Demonstrate these principles in classroom exercises, homework problems and examinations based on applying knowledge to solve analytical problems. 
3. Draw a free body diagram
and solve for unknown forces in two and three dimensions for particle and
rigid body systems. Demonstrate analytical skills by solving for unknown
forces.

Demonstrate these principles in classroom exercises, homework problems, examinations, and final report based on applying knowledge to solve analytical problems. 
4. Students will be able
to perform vector operations of dot and cross product and use these principals
to solve for unknown forces in three dimensions. Demonstrate the ability
to use the concepts of moments and couples in qualitative and quantitative
applications.

Demonstrate these principles in classroom exercises, homework problems and examinations based on applying knowledge to solve analytical problems. 
5. Apply the method of
joints and sections to determine the forces in a truss ’s members. Obtain
the ability to determine joint reactions of simple frames or machines.

Demonstrate these principles in classroom exercises, homework problems and examinations based on applying knowledge to solve analytical problems. 
6. Students will understand
the concept of friction and analyze rigid bodies subjected to dry friction.

Demonstrate these principles in classroom exercises, homework problems and examinations based on applying knowledge to solve analytical problems. 
7. Understand the concepts
of center of gravity, center of mass, and the centroid. Be able to calculate
the center of gravity and centroid of shapes.

Demonstrate these principles in classroom exercises, homework problems and examinations based on applying knowledge to solve analytical problems. 
8. Be able to conceptualize
fluid pressure and calculate hydrostatic forces.

Demonstrate these principles in classroom exercises, homework problems and examinations based on applying knowledge to solve analytical problems.
