Textbook:

1. “Statics and Mechanics of Materials”, R.C. Hibbeler, Prentice Hall, 2nd Edition

2. “Shigley’s Mechanical Engineering Design”, R.G. Budynas and J.K. Nisbett

Grading: Homework 30 %,  Midterm exam 25 %, Lab 20 %, Design Project 10 %, Final exam 15 %
Homework: Homework will be due one week after it has been given, except when otherwise advised. Homework must be submitted at the beginning of the class on the day it is due. Late submissions will be penalized 20 % for every day it is late up to one week. After one week, homework will not be accepted.
Exams: Midterm I (Mar. 5), Midterm II (Apr. 11), Final (May 14, 2-5pm)
Labs: Laboratory times are W. 3:30-5:00pm, Th. 1:30-3:00pm or Th. 4:30-6:00pm. Laboratory locations will be identified as needed (Krieger HAC or Wyman 163). You may choose between the three laboratory times at the beginning of the semester. Attendance at the laboratories is mandatory. There will not necessarily be a laboratory every week; there are no laboratories in the first week.
Grading: Homework (30%), 2 Midterm exams (25%), Labs (20%), design Project (10%), Final exam (15%)
