MEC2401 - Dynamics I

Leader(s): R Ibrahim, H L Liew (Sunway)

Offered

Clayton First semester 2009 (Day)
Sunway First semester 2009 (Day)

Synopsis

This unit introduces the second year mechanical engineering students to the concepts of time, space, coordinate systems, particles, rigid bodies, forces, work, energy and Newton's Laws of Motion. The students will be instructed on particle kinematics and kinetics, systems of particles, planar kinematics and kinetics of rigid bodies and moments of inertia. They will also be presented with an introduction to 3-dimensional dynamics of rigid bodies. Work-energy and impulse-momentum methods will also be covered. The fundamentals of mechanical vibration, analysis and synthesis of planar mechanisms and experimental modelling will complete the unit.

Objectives

On completion of this unit, students will be able to:

1. Handle engineering problems which involve displacement, velocity and acceleration

2. Reliably calculate forces, power and energy losses involved in practical engineering applications

3. Express engineering solutions in a realistic and logical format using the appropriate units, dimensions and accuracy

4. Understand the fundamentals of kinematics and kinetics of particles and rigid bodies

5. Apply these principles to solving engineering problems involving: simple vibrating systems of masses, springs and dampers. Analysis of simple engineering mechanisms

6. Appreciate the difference between kinematics and kinetics

7. Apply these skills to solve engineering mechanics problems

8. Relate kinematics and kinetics in solving engineering mechanics problem.
