ME 121 FALL 2004  HOMEWORK ASSIGNMENT 1- Sept 10, 2004

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

GOALS

• Provide understanding of the fundamental concepts of position, velocity, and acceleration in simple engineering systems involving motion of points in straight lines or curved paths.

• Use of acceleration, velocity, position for rectilinear motion; cases of given acceleration a(t), a(v), a(s).
• Use of acceleration, velocity, position for curvilinear motion.
• 2-D motion of projectiles in absence of air resistance.
• Velocity and acceleration in 2-D curvilinear motion in terms of normal and tangential components.
• Use of SI units in dynamics (kg, m, s, N).

Reading assignment
Chapter 12 (Introduction). Read all.   Chapter 13 (Motion of a Point): pp. 19-68.
Make sure you read especially carefully ALL the solved examples.
If you want additional practice, note that even-niumbered problems have answers in back of book.

    Pease make sure that your problem sets are NEAT and LEGIBLE. The graders will take off or award extra points for poor or professional presentations.

    Basic guidelines for the PROFESSIONAL presentation of your homework:

• Solve each problem on a different page. Number each problem, i.e. 1) Problem 12.15, etc.
• Write your name on first page you turn in, your initials on all other pages.
• On front page write "ME 121, HOMEWORK No. ____, Due Date ____"
• All pages should be stapled together.
• Surround your final answer(s) in a box. Make sure you indicate appropriate units.
