Problems and Reading Assignments
are from DYNAMICS
(4th ED.), Bedford & Fowler (Prentice Hall, 2005)
GOALS
- Provide working
knowledge of rigid body (RB) planar motion
(kinematics), in terms of translation and rotation.
- Understand the difference between
translation and rotation.
- Motion of a RB about a fixed axis
vs. general motion.
- Provide working knowledge of the
fundamental concepts of
linear velocity and acceleration in rigid body motion
- Provide working knowledge of the
fundamental concepts of
angular velocity and acceleration in rigid body motion.
OBJECTIVES
- Working ability with
and conversion between SI and English
systems of units in dynamics (slugs and kg, lb and N, ft and m).
- Special attention to SI units in
dynamics (kg, m, s, N).
- Use of linear velocity and
acceleration in simple components
and systems.
- Use of angular velocity and
acceleration in simple components
and systems.
- Kinematic analysis of simple planar
mechanisms.
- Introduction to sliding contacts.
