Homework
Problems will be assigned on Thursday of each week and collected six days later
on the next Thursday (before or after the lecture, BUT NOT DURING THE LECTURE).
The usual practice will be: “No late homework”. Solutions to the homework will
be available a few days after they are due. Homework problems may be discussed
with fellow students and consultation with the professor or TA for general
direction on problems is encouraged; however, solutions must be your own work.
Do not be surprised if a problem solved by the professor or TA during the
lecture or discussion session is given as an exam problem.

Announcements
Office hours for Fridays have been changed
They
will now be at 11:30am – 12:30pm and 2:00pm – 3:00pm in EBU II 305.
Dr. Nesterenkos office hour has been
changed. It is on Thursdays from 5-6pm.
As of today, 11-5-08, midterms can be picked up from Aimee in her
office, EBU II 281. You will need to show her ID to receive you midterm. Old
graded homework will now be available outside of her office in a box marked
MAE131A on the table. Each week the TA will place the homework outside of her
office after it has been returned in class.
Midterm 2 topics
3D Hooke’s law: Make sure that you know how to do problems for a composite with
Young’s modulus and Poisson’s ratio that might not be the same in all
directions.
Torsion: Know how to handle problems involving Tau, Theta and Phi. Make
sure that you understand the homework and similar problems.
Bending:
1) Bending of beams, beams that have applied moment and may be
fixed at one end.
2) Composite beams i.e. may be made of concrete with steel
reinforcement.
Midterm 2 will cover the
material from the middle of homework 3 through homework 6.
