The instructor reserves the prerogative to adjust the location and/or width of the GradeAssignment bands based solely on his professional judgment of overall class performance.
NOTE: Keep ALL your GRADED work until AFTER you have received your final grade. This
grading record will help to substantiate any grade-recording errors committed by the instructor.
General Expectations
In ENGR-36, ENGR-43, and ENGR-45 the instructor expects each student to
exhibit the demeanor, comportment, and sense of responsibility consistent
with those of a practicing engineer.
Doing Well In This Course
This Course is PROFESSIONALLY important. EVERY Engineer should be able to determine
the support reactions on a static and (assumed) rigid structure given external force loading.
Those engineers in the structural disciplines of CIVIL and MECHANICAL engineering must also
be able to determine the INTERNAL loading of structural elements as part of a detailed stress
analysis.
To best learn the course material:
1. EXPLOIT The REQUIRED TextBook
© Bruce Mayer, PE • Chabot College • Document1 • Page 2

2.
3.
4.
5.
6.
3
Buy cheap BEER3; not cheap TextBooks
o Every Student’s future WORKING LIFETIME depends, in some part, earning a good
grade in this course.
 Making the Optimum Book Choice improves a student’s probability of
Success in this course
 Do NOT buy: OLD Editions or International Editions
 Good Condition USED books of the proper edition are aOK
 Do NOT RENT or SELL textbooks that relate to a student’s Career
Choice
 Do not merely read the text; WORK the text
o Obtain the Required TextBook IMMEDIATELY and start USING it
o BEFORE attempting the HomeWork assignment, go thru the chapter with a PENCIL
& PAPER.
 Work the EXAMPLE problems until you can solve them without referring to the
text solution
LISTEN to the Instructor
 A second point of view that differs from the TextBook aids understanding
 What the instructor covers in his/her OWN WORDS usually ends up on Exams
LEVERAGE THE LAB TIME
 The instructor will solve, IN DETAIL, Force & Moment loading problems during the labs.
Pay close attention and ask questions and/or point out errors in the instructor’s
presentations
o If you have questions after Lab is over, then review the solutions which are posted to
the Course WebSite
 After the instructor completes his problem-solution work with the instructor and/or your
colleagues to solve troublesome homework problems
o Use the WhiteBoard whenever possible so other students can observe as the
“Problem Team” works thru the solution.
Think PHYSICALLY
 This is NOT a MATH class; rather it’s an engineering class that uses sophisticated
mathematics
o Try to understand the how the mechanical-structure responds to external loading in
terms of Pushes & Pulls (forces), and Twists (moments or torques) and not just in
terms of abstract symbols.
o Use UNITS to the maximum possible extent. Units connect an Engineer’s thinking to
the Real, Physical World
DRAW LOTS of DIAGRAMS
 When analyzing a physical structure REDRAW it OFTEN; sometimes after EVERY
analytical step
 Sometimes just “UnTangling” a structure can reduce the solution-difficulty by 90%.
 Sometimes Draw to SCALE. A Scaled drawing can reveal relationships within the
structure that a schematized diagram obscures
 Use MATLAB or EXCEL to graph data of analytical Solutions. Recall the Instructors
Advice from ENGR25
o When in Doubt GRAPH it. If you don’t know when to doubt, GRAPH it ANYWAY
PUT IN the TIME
Applies to students 21 years of age or older
© Bruce Mayer, PE • Chabot College • Document1 • Page 3

A serious engineering student will spend 6-8 hours per week OUTside of class studying
the course-material and/or preparing Lab Problem Sets
 Stay on the assignment schedule to avoid “Rush Jobs” that produce MINIMAL learning,
and to avoid Late Penalties
7. ASSIST your COLLEAGUES and/or CREATE a STUDY GROUP
 One of the best ways to LEARN something is to TEACH it to someone else.
o If a ClassMate seeks your assistance with the HomeWork or in the Lab, do your best
to accommodate him/her with a careful explanation
 Some possible locations for Study Groups to meet include:
o The MATH & SCIENCE CENTER in room 3906
o The LIBRARY
How to Study Like a College Student - EXTRA CREDIT
Students can earn EXTRA Credit in the maximum amount of a 50-Point HomeWork
Assignment by completing the Take Home Quiz based on the College Student Study Skills
presentation.
 The Presentation can be found on the Course WebPage
 The Take Home Quiz (THQ) is due as noted on the schedule
o NO Late THQs accepted
eMail Communication → SpamFilter Avoidance = “ENGR36”
On ALL eMail communication students should please include the text “ENGR36” in the subject
line. Otherwise the student eMail may be sent to the college SpamFilter folder which is not often
inspected by the instructor.
Supplies and Equipment
Required
 Scientific Calculator (NO Cell Phone Calculators allowed on Exams)
 Engineering Computation Pad, 8.5” x 11”, Green Background, 0.2” Grid
Recommended
 Access to MATLAB or EXCEL Computer Software
o Excel Available in the Computer Science Lab, Room 3906
o $99 Student Version available → https://www.mathworks.com/programs/nrd/buymatlab-student.html?s_eid=ppc_3302
 0.5 mm, Quality Mechanical Pencil
 Quality Straight-Edge Ruler
 Circle Template
Others As Announced by the Instructor during the Course of the Semester

Attendance
Grade-Performance in this course correlates strongly with class attendance; students who
attend class sessions statistically receive better grades than students who miss lecture and/or
laboratory sessions. The KEY to meeting the course goals is CONSISTENCY – Come to class
EVERY time, complete EVERY HomeWork and Lab assignment ON-TIME.
A Student will be dropped from the class if he/she misses two, or more, class periods during the
first two weeks of the term.
Coming-Late or Leaving-Early should be rare events. If a student needs to arrive late or leave
early, please find a seat near the door. Please enter or leave quietly, so as to not disturb the rest
of the class. Instructors consider a student walking between the instructor and the class to be a
very inconsiderate and discourteous act.
Lab Problem Sets
1. All Lab Problems will be accomplished on the Mastering Engineering OnLine Homework
& Learning System as described in the “Course Logistics” section of this syllabus
2. Do not miss Classes or Labs; if you miss a session you are responsible for obtaining any
class material through consultations with your colleagues (class-mates), or in some cases
through accessing the course WebPage
3. If you have difficulty with any aspect of the Problems Sets; follow this escalation procedure
 Try again yourself, consulting reference books, websites, etc., if practical.
 Use the Mastering Engineering “Hints” feature
 Consult with your colleagues (remember, they have their own work to do)
 Consult with the instructor (in Professional Engineering Practice you HAVE NO
INSTRUCTOR that knows the answer).

Homework
Any Lab Problems not completed
during the lab period must be done as
homework. No additional homework
beyond the LPS will be assigned
 Caveat: statics is best learned
by working MANY Problems.
Students are encouraged to
work through examples shown
in the text, and by working
chapter problems for which the
text provides answers.
An Example of a Mastering
Engineering Assignment is shown at
right
HOMEWORK JOURNALS
Since Exams in ENGR36 are done by
HAND, students should work thru the
HomeWork by HAND as well. While
completing the OnLine HomeWork
assignments students must work the
problems on paper, and then enter
the
answers
into
Mastering
Engineering. Students will collect this
HandWork in an inexpensive, paperretaining Folder that will then constitute a HomeWork Journal (HWJ). Students then turn-in the
HWJ’s on the Due Dates noted on the schedule. To receive full credit for the HWJ, a student
must:
 show all his/her work (no work  no credit)
 be neat; If it can’t be read, it can’t be understood or graded
 start each Assignment on a new page with the chapter and assignment number in the
upper right hand corner
 put assignments in chronological order based on the date of the assignment; the oldest
assignment first
 securely fasten all assignments in a Soft-Cover Folder (NOT a binder) with a paperretaining mechanism similar to that shown in Figure 3 to form the Homework Package as
indicated in the schedule.
o The FIRST page on the
inside of the folder must be
the
ENGR-36/43
HomeWork Package Cover
Sheet (Figure 3, left photo)
Figure 2 • ENGR36 Mastering Engineering Late
HomeWork Penalty-Algorithm
© Bruce Mayer, PE • Chabot College • Document1 • Page 7


Copies of the CoverSheet will be provided before HWJ-1 is due
The HWJ CoverSheet MSWord File may Also be DownLoaded from the
Course WebPage
o The student name must be VISIBLE with the folder CLOSED
o turn in all the assignments for the HomeWork Journal as noted in the schedule
Figure 3 • Homework-Journal folder. The Cover Sheet (right) must be the first Page. The folder must BIND the
stapled Homework Assignments. Note: please use Binding FOLDERS ONLY; please do NOT submit ThreeRing
Binders.
MiniQuizzes
40-50, single-problem “MiniQuizzes” will be administered during the course of the term. The
MiniQuizzes (or MQs) will be “pop” in nature; that is, the MQs are not announced in advance.
Some details on the MQs:
 MQs may be administered at ANY time during the class period
 Some Class Meetings will have NO MQ
 Some Class Meetings will have MORE THAN ONE MQ
 MQ content will consist of the subject matter covered during the previous class meeting
o Content may be drawn from either the Lecture or TextBook
 MQ Duration shall be 5 minutes. MQs will be collected promptly after the 5 minute
duration; NO extra time will be allowed for any reason.
 There will be NO MakeUp MQs for any reason
 MQ’s will NOT be Returned
 MQ Scoring:
o 0 Points → Student does not take the MQ
o 1 Point → Student takes the MQ, but shows NO, or LITTLE, evidence that the
student gave his/her full attention to the previous lecture(s) and reading(s).
o 2 Points → Student takes the MQ and shows SUBSTANIAL evidence that the
student gave his/her full attention to the previous lecture(s) and reading(s) but the
student arrives at an incorrect result.
© Bruce Mayer, PE • Chabot College • Document1 • Page 8
o 3 Points → The student arrives at the correct result AND Demonstrates
UNDERSTANDING of the course material presented
Exams
Exams are CLOSED-Book. However, proper solution to many static-loading problems requires
reference to not-easily-recalled mathematical relations. For this reason students may bring to
the exam a reference sheet prepared by the student.
 Requirements for the Student Reference Sheet (SRS)
o A single, 8.5”x11” sheet of paper – Both Sides OK
o The “SRS” MUST be HAND-WRITTEN; No PrintOuts or PhotoCopies permitted
 MakeUp exams are only offered in those cases where the student can provide 3 rd party
justification (e.g., a note from a medical doctor) for the absence.
o Any MakeUp exam must be taken the NEXT day, at a time & location determined
by the instructor.
o All MakeUp exams are subject to a 15% score-penalty.
 MakeUp exam takers have extra study time, and that is NOT FAIR to those
students who make the (sometimes extraordinary) effort to come to the
exam on-time.
 NO Cell-Phone Calculators are allowed on the Exams – Students are requested to
bring a stand-alone Scientific Calculator to Exams.
Use of material other than the student reference sheet, or use of a Cell-Phone during the
exam shall be considered a serious instance of ACADEMIC DISHONESTY
Withdrawal From Course
After the NGR date any student wishing to withdraw from the course to receive a “W” on his/her
grade-transcript MUST, to completely avoid an “F” grade, initiate the withdrawal through the
Admissions & Records process. In other words, the STUDENT must drop the course either using
CLASS-WEB, or in-person in the Community Student Services Center, Bldg-700.
 Do NOT ASSUME that the instructor will drop any student from the course
The instructor MAY drop students from the course at the “Last day to drop with a ‘W’ (Withdraw)
as indicated in the “Academic Calendar” published in the Chabot College class schedule. The
“W-Date” is typically about 70% of the way thru the term. Any student who fails to take the course
seriously earns a W. Evidence of a lack of commitment to the course includes any of these Wearning actions:
 Not Completing MiniQuizzes for 3 weeks prior to the W-Date
 Not completing HOMEWORK and/or LABS for 3 weeks prior to the W-Date
 Not taking a MIDTERM EXAM
© Bruce Mayer, PE • Chabot College • Document1 • Page 9
WARNING: After the “W date” the Instructor is OBLIGATED
by College Policy to give all enrolled students Letter Grades.
ONLY Chabot COUNSELING can approve “Late W’s”.
Student Conduct
Everyone in this class, including the instructor, is a mature adult, so Courteous and Respectful
behavior is expected at all times.
 Please & ThankYou go a long way to make a pleasant atmosphere.
 Swearing is not appropriate for the classroom.
 Do not talk if another student or the instructor is talking.
 If a student Arrives LATE or leaves EARLY, then please, please:
o Enter/Exit VERY Quietly
o Do NOT, repeat, do NOT walk in front of the PowerPoint Projector Image
Student conduct, and consequences for misconduct, shall follow the policies described in the
STUDENT RIGHTS AND RESPONSIBILITIES” section of the Chabot College course catalog.
 The minimum sanction for misconduct shall be removal of the student from Class for the
remainder of the class period
Pagers, Cell Phones, Handheld Computers, and Similar Devices: Must be set to a NONAUDIBLE Condition.
 After one warning, subsequent violations shall result in a grade sanction equivalent to a
missed Homework assignment
VISITORS: Note that Chabot College policy does NOT allow visitors in the classroom.
EATING: Please eat all food outside the classroom.
BE PREPARED: Bring paper, your book, and extra pencils or pens. Sharpen your pencils before
the class starts. Take care of your personal needs before class starts.
PICK UP AFTER YOURSELF: Put all trash in the waste paper basket. Check your desk area
before departing to ensure that you have not left any personal items. If you are working in groups,
please return your desk to its original position.

Academic Dishonesty
Academic Dishonesty of Any Kind WILL NOT BE TOLERATED
Any act of academic dishonesty
 Will result in a grade of ZERO (0) for the assignment/task in which the offense occurred
 May result, in the sole discretion of the instructor, in the assignment of a grade of F for
the COURSE
 May trigger the formal Chabot College Academic Dishonesty discipline process as
described in the “STUDENT RIGHTS AND RESPONSIBILITIES” section of the Chabot
College course catalog
