|School||School of Engineering
||College||College of Science and Engineering
|Credit level (Normal year taken)||SCQF Level 8 (Year 2 Undergraduate)
||Availability||Available to all students
|Summary||This course aims to provide a basic understanding of the Laws of Newtonian Mechanics for bodies and systems of bodies in plane motion, and to achieve proficiency in their use in conjunction with kinematic principles for a range of mechanical engineering applications.
1. Dynamics of Particles
Newton's Laws of Motion and the nature of forces; D'Alembert approach; dynamical laws of single particle; dynamical theorems for systems of particles; Linear and Angular momentum; mass centre properties; motion in polar coordinates; Coriolis acceleration. Central Force motion and orbits.
2. Systems of Bodies
Rigid body as a model; dynamical laws for rigid bodies in pure translation, fixed axis rotation and general plane motion; inertia couple; moments of inertia; inertia theorems; rolling versus sliding. Kinematic relations between interacting bodies: circular motion, gear drives, belts and pulleys, rolling on a plane. Applications to coupled systems, power transmission, simple vehicles, rotational unbalance, static and dynamic-balancing of rotors; introduce balancing of reciprocating mechanisms.
3. Work - Energy Approach
Kinetic and potential energy; work and power; work-energy theorems applied to system calculations; the conservative system as a special case.
4. Oscillatory Motion
Introduction to oscillations; differential equations of translational and rotational SDF systems, free vibration, natural frequency; damping and critical damping; introduction to resonance, features of vibratory phenomena.
5. Gyroscopic Torque
Introduction to gyroscopic torque and gyroscopic effects; angular momentum vector of a rotor; precession applications.

||Degree Examination 50%; Coursework 50%
The School has a 40% Rule for 1st and 2nd year courses, i.e. you must achieve a minimum of 40% in coursework and 40% in written exam components, as well as an overall mark of 40% to pass a course. If you fail a course you will be required to resit it. You are only required to resit components which have been failed.
||Hours & Minutes
|Main Exam Diet S2 (April/May)||1:30|
|Resit Exam Diet (August)||1:30|
On completion of this course, the student will be able to:
- Model mechanical systems as plane assemblies of masses and inertias, and draw clear accurate linked free-body diagrams.
- Identify kinematic relations between coupled elements using cables, gears and pure rolling.
- Calculate moments of inertias of a range of assemblies, using parallel axes and perpendicular axes theorems.
- Formulate energy expressions for systems and use concepts of work and power to determine motion.
- Understand the properties of single degree of freedom oscillatory systems, and the importance of resonant systems in engineering.
