### Methods of Instruction

Class time is devoted to lectures and problem solving.

### Means of Assessment

Evaluation will be carried out in accordance with Douglas College policy. The instructor will present a written course outline with specific evaluation criteria at the beginning of the semester. Evaluation will be based on the following:

Assignments            10-20%

Project                     10-20%

Tests                       30-50%

A minimum of two tests will be adminstered during the semester.

Final Exam               30-40%

### Learning Outcomes

Upon completion of the course the student will be able to:

1. analyze two and three dimension concurrent force systems acting upon particles in equilibrium
2. analyze the equilibrium of rigid bodies in two and three dimensions and determine equivalent systems of forces
3. analyze structures and their internal forces
4. apply the concepts of friction to practical problems
5. analyze motion of particles and particle-like objects and systems using displacement, velocity, acceleration, force, Newton’s second law, energy, momentum, conservation principles.
