MEEN 2355 Statics and Dynamics
FINAL EXAM REVIEW SHEET
The exam will be 2 hours, but I will be there early.
Each person is allowed 1 8.5 x 11 sheet! (On this sheet you can handwrite anything, on 1 side
only.)
The exam will be closed book and closed notes.
Any calculator is allowed; I will not have a calculator to lend out.
You must show all your work on the exam to get full credit.
If you are caught cheating, copying from some else’s exam, or knowing let someone copy
from your exam; you will be given an F for the test. I may also drop you from the course.
Budget a certain amount of time per problem, if you do not finish it, go on to the next
problem. Know your calculus relations.
