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 should be handed in in class the day on which they are due.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.

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 5-8 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.

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 human-caused incidents with the ultimate goal of maintaining a safe and secure campus. Letís 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., x-y or n-t) and location for the various problem types.
