ME 121 FALL 2004  HOMEWORK ASSIGNMENT 8 - Nov 8, 2004

DUE IN CLASS (Notice Due Date)
FRIDAY, NOVEMBER 12, 2004

Problems and Reading Assignments are from DYNAMICS (3rd ED.), Bedford & Fowler (Prentice Hall, 2002)

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

• 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.

Reading assignment

Chapter 17 (Planar kinematics of rigid bodies): Sections 17.1 to 17.4.
Make sure you study especially carefully ALL the solved examples.
If you want additional practice, note that even-numbered problems have answers in back of book.
