Mechanics II

**
Subject Description
**

This course is a continuation of MEC110. It is designed to provide the student with a thorough understanding of the basic concepts of the kinematics and kinetics of particles, systems of particles and rigid bodies. Topics dealing with the rigid bodies cover two types of motion: plane translational motion and rotation about a fixed axis. Those topics include also the determination of the equations of motion describing the relations between the applied forces and moments on one hand and the resulting motion on the other hand.

Moreover, the course covers energy and power methods, linear and angular momentum and the principle of impulse and momentum.

The topics delivered are essential to the study of the aviation applied subjects such as: Aerodynamics, Aircraft structures, Flight propulsion and Aircraft stability and control in higher semesters.

Learning Outcomes
**

Upon successful completion of this subject the student will be able to:

1. Analyze and solve problems involving particles undergoing uniform rectilinear motion, uniformly accelerated rectilinear motion or two-dimensional projectile motion.

2. Analyze, using a free body diagram (or diagrams), the unbalanced force system acting on a particle undergoing rectilinear or curvilinear motion in two dimensions and use Newton’s second law to calculate the required unknowns such as linear acceleration, etc.

3. Analyze the motion of systems of fixed number of particles, systems with variable number of particles and steady stream of particles.

4. Define the concepts of work, kinetic energy, potential energy and power and use these concepts to calculate the required unknown parameters such as velocity (or velocities), position(s) etc. for systems of particles acted on by unbalanced force systems.

5. Use the principle of conservation of energy to calculate the required unknown parameters such as velocity (or velocities), position(s) etc. for systems of particles acted up on by conservative force systems.

6. Define the terms impulse and momentum and use these concepts, along with the concept of energy when necessary, to calculate unknown parameters such as velocities, positions etc. for systems of particles acted on by unbalanced force systems.

7. Write down all the equations linking the parameters of linear motion and those of angular motion and use these equations to solve problems involving the motions of rigid bodies which rotate about fixed axes.

8. Analyze, using a free body diagram (or diagrams), the unbalanced force/couple system acting on a given rigid body undergoing any plane translation or rotation about a fixed axis. The student will also be able to use the general equations of motion to calculate the required unknown parameters of the motion and any required unknown external forces or couples.

9. Apply the fundamental concepts of systems of particles to introduce the principles of some aviation applications like the jet engines, fans, propellers, helicopters etc.

Academic Integrity
**

Seneca upholds a learning community that values academic integrity, honesty, fairness, trust, respect, responsibility and courage. These values enhance Seneca's commitment to deliver high-quality education and teaching excellence, while supporting a positive learning environment. Ensure that you are aware of Seneca's Academic Integrity Policy which can be found at: http://www.senecacollege.ca/about/policies/academic-integrity-policy.html Review section 2 of the policy for details regarding approaches to supporting integrity. Section 2.3 and Appendix B of the policy describe various sanctions that can be applied, if there is suspected academic misconduct (e.g., contract cheating, cheating, falsification, impersonation or plagiarism).

Please visit the Academic Integrity website http://open2.senecac.on.ca/sites/academic-integrity/for-students to understand and learn more about how to prepare and submit work so that it supports academic integrity, and to avoid academic misconduct.
