during lecture.
COURSE OBJECTIVES
This course covers the fundamental principles of solid mechanics,
including stress & strain, Hooke’s law, equilibrium equations,
reactions, internal forces, torsion, beam bending and deflection,
and deformation in simple structures. The course integrates aspects
of solid mechanics that have applications to civil (buildings) and
mechanical structures (engines and wings). Advance topics may
include stress concentration, fracture, plasticity, fatigue,
viscoelasticity and thermal expansion. The course synthesizes
descriptive observations, mathematical theories, and engineering
consequences.
COURSE GRADE
Weekly Homework Assignments: 15%
Mid-term Exam I: 20%
Mid-term Exam II: 20%
Final Exam: 40%
Quizzes: 10%
HOMEWORK ASSIGNMENT
1) Assignments will be emailed to you; due on Thursdays at 2:00 PM in class unless
otherwise stated.
2) Late assignments are accepted on the 20% reduction daily basis.
3) Neatness is important!
 Use a pencil. Mechanical pencils are recommended.
Write neatly and clearly. Your TA may lose patience with illegible
solution sets.
Write your first and last name, the course number, the assignment
number and the due-date in the upper right corner of the first page. Write
the page number on each page (e.g., 3/6, means page 3 of 6)
Use a straight edge (a ruler or a triangle) to draw straight lines.
Present solutions to problems in the same order as listed in the
assignment, and begin every problem on a new page unless the next
solution is so short that it can fit on the same page.
Partial credit will be awarded only if the solution leading to an incorrect
answer describes your thinking in words.
Draw a box around your final answer and provide the units associated
with your answer
Staple your solution set.
4) Grading: The TA will grade each homework assignment out of 100 points.
5) Show all units.
6) Present all steps in solving a problem. Correct answers with no work showing
will receive 0.
7) On cover sheet or first page include your name, CEN 202, date and homework
number.
8) Use engineering paper for homework. Use one side only. Start a new problem
on a new sheet.
9) Homework solutions will be placed on the bulletin board outside of Violette
Research 108 when graded homework solution sets are returned.
NOTES
1. 20% reduction will be applied to the late assignments on a daily basis unless prior
approval of the instructor is obtained.
2. Any form of academic dishonesty will result in the issuance of an F grade for the
course and possibly other departmental action. See Student Handbook and/or UMD
General Catalogue for definition of academic dishonesty:
http://www.umassd.edu/studenthandbook/academicregs/ethicalstandards.cfm
3. Any requests for exceptions to due dates, the grading system, or exam dates and times
must be submitted to the instructor in writing for approval. If approved, your request will
be returned to you with my initials. Verbal agreements are easily misunderstood or
forgotten, and are therefore not valid.
4. The College of Engineering provides tutors through the Science and Engineering
Center, located in Group II, room 217B. The director is Mr. John Fernandes and his
phone extension is -8718. You must schedule your appointments with the tutoring center.
5. Students with physical, learning, or other disabilities may wish to contact the Center for
Access & Success, Pine Dale Hall, Room 130, Phone 508-999-8711. Pine Dale Hall, Room: 130
for assistance and accommodation.
