In case you need to address questions to my professors, let me know so I can address them. The only source you can use is the one I provided.

Note from the professor “Hi Everyone–Please type up answers to the exam that are easy to type and handwrite the rest. You do not need to spend hours drawing mechanisms. It is easier for us to grade if things are typed, so do as much as is possible. The handwritten stuff should be neat and tidy.
Question #4 refers to Equation 19.59 on page 903 of your text, not the book chapter that is posted.
Remember that the due date is Monday by 5pm. Please submit to Dr. A. If he is not available, have Sarah time-stamp your exam and she can take it.”
