MAS112 Dynamics

Contents and structure

This course concerns the kinematics (motion) and kinetics (forces that cause motion) of both particles and bodies. It exploits rotation matrices and moving frames for the analysis for both 2D and 3D motion. The course introduces the following topics: linear momentum, angular momentum, work, energy and conservation principles. Students will learn a simple math software package and apply it to problems in dynamics. Students will be introduced to the mechanics of gears, links, rolling wheels, cams, rotating axial members and gyroscopic effects. The lectures, exercises and exams will be given in English.

Content

• Single Particles: Kinematics, Kinetics, Work, Energy, Momentum.
• Two Particles: the above, plus contact and collision
• Many Particles: the above, plus the concept of centers of mass
• Kinematics of bodies in two and three dimensions
• Kinetics of bodies in two and three dimensions: Newton's and Euler's Equations
• Kinetic analyses of axial members and gyroscopic effects

Learning Outcome

After completing the course MAS112 the students will possess the following:

• An understanding of kinematics (translation and rotation) and the kinetics (force and moments) in both two and three dimensions.
• An understanding of simple mechanisms.

• Apply Newton's Laws of motion on particles and bodies.
• Understand the mechanics of links, gears, gyroscopes, rolling wheels and other mechanisms.
