Office Schedule Spring 2017 












Official office
hours are in green.
However, my door is open pretty much whenever I'm in the office. If the door is open, you're welcome to stop
by. If, for some reason, I'm too busy to
talk with you, we'll make an appointment.
Homework:
You will learn much
more if you do the homework. All
homework sets must be submitted electronically through Blackboard. Each set must be submitted as a single PDF
file. Every homework problem is
worth 10 points. Feel free to work with
one another on homework as long as everyone is participating and learning. Everyone must hand in their own work.
Homework sets handed in up to one week late will be
penalized 50%.Homework will not be accepted more than one week late without
prior arrangement.
For all homework

Extra Credit:
I want students to
start noticing dynamics in the world outside of class. To foster this, each student may bring in an example
that demonstrates some principle from class.
You will be asked to give a 58 min explanation to the class. If your example and explanation are correct
and relevant, two points will be added to your final class average. Each student may do two demonstrations during
the semester.

Intro Homework: 1 – A car accelerates from a standing
start at a rate of 4 m/sec^2. A truck
500m down the road accelerates from a standing start at a rate of 2
m/sec^2. How far has the car traveled
when it catches the truck? How many
seconds does it take? 2 – An MET student want to throw a golf
ball to the 6^{th} floor window of a building. She is next to the building, so there is no
horizontal motion. The window is 22m
above the release point. What is the
initial velocity of the ball? Submit your solutions on Blackboard. Due

Safety:
As we begin this semester I want to take a few minutes
and discuss emergency preparedness. Purdue University is a very safe campus and
there is a low probability that a serious incident will occur here at Purdue.
However, just as we receive a safety briefing each time we get on an aircraft,
we want to emphasize our emergency procedures for evacuation and shelter in
place incidents. Our preparedness will be critical if an unexpected event
occurs.
Emergency
preparedness is your personal responsibility. Purdue University is continuously
preparing for natural disasters or humancaused incidents with the ultimate
goal of maintaining a safe and secure campus. Let’s review the following
procedures:
·
There are nearly 300 Emergency Telephones
outdoors across campus and in parking garages that connect directly to the
Purdue Police Department (PUPD). If you feel threatened or need help, push the
button and you will be connected immediately.
·
If we hear a fire alarm, we will
immediately suspend class, evacuate the building, and proceed outdoors,
and away from the building. Do not use the elevator.
Course Objectives:
Upon successful
completion of this course, the student should be able to:
1. Distinguish
between problems requiring a Statics solution and problems requiring a Dynamics
solution (i.e., Bodies that require a Statics solution have no acceleration.)
2. Identify
the different types of dynamics problem (i.e., Kinematics, Kinetics, Rigid
Body, Particle).
3. Select
the appropriate solution method for the different problem types (i.e.,
Kinematics, Equation of Motion, Work/Energy Principles, Conservation of Energy,
Impulse/Momentum, and Conservation of Momentum).
4. Properly
apply each of the solution methods.
5. Properly
construct motion diagrams for the solution of Kinematics problems.
6. Properly
draw supporting diagrams for Kinetics problems (i.e., Free Body Diagram,
Kinetic Diagram, Impulse/Momentum Diagram, etc.).
7. Properly
calculate the mass moment of inertia for basic and composite shapes.
8. Select
the appropriate coordinate system type (i.e., xy or nt) and location for the
various problem types.
