Information Dissemination
Handouts will be printed out and provided before each lecture
PPT lecture slides will be made available online at lab website
I intend to also provide MP3 audio files
Homework solutions will be posted at Learn@UW
Grades will be maintained online at Learn@UW
Syllabus will be updated as we go and will contain info about
Topics we cover
Homework assignments and due dates
Exam dates
Available at the lab website
Homework
I’m shooting for weekly homeworks
Assigned at the end of each class
Typically due one week later, unless stated otherwise
No late homework accepted
I anticipate 11 homeworks
There will be a bonus ADAMS project
You’ll choose the project topic, I decide if it’s good enough
Worth two HWs
HW Grading
50% - One random problem graded thoroughly
50% - For completing the other problems
Solutions will be posted on at Learn@UW
MATLAB and Simulink
MATLAB will be used on a couple of occasions for HW
It’ll be the vehicle used to formulate and solve the equations governing the time evolution of mechanical systems
You are responsible for brushing up your MATLAB skills
I’ll offer a MATLAB Workshop (outside class)
Friday, January 30, from 1- 4 PM, in 1051ECB
Tutorial offered to ME students at large
Register if you plan to attend, seating is limited
Topics covered: working in MATLAB, working with matrices, m-file: functions and scripts, for loops/while loops, if statements, 2-D plots
Kinematics Analysis
Concerns the motion of the system independent of the forces that produce the motion
Typically, the time history of one body in the system is prescribed
We are interested in how the rest of the bodies in the system move
Requires the solution linear and nonlinear systems of equations
Dynamics Analysis
Concerns the motion of the system that is due to the action of applied forces/torques
Typically, a set of forces acting on the system is provided. Motions can also be specified on some bodies
We are interested in how each body in the mechanism moves
Requires the solution of a combined system of differential and algebraic equations (DAEs)
