The instructor reserves the prerogative to adjust the location and/or width of the Grade-Assignment 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 instructors expects each student to exhibit the demeanor, comportment, and sense of responsibility consistent with those of a practicing engineer.

Doing Well In This CourseThis 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.

ENGR36 Course-Score Weighting Function

Figure 1 • Course-Grade Weighting Function in Graphical Form

Buy cheap BEER3; not cheap TextBookso 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 ito 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 solution2. 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

3. 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 presentationso 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 problemso Use the WhiteBoard whenever possible so other students can observe as the

“Problem Team” works thru the solution.4. Think PHYSICALLY

This is NOT a MATH class; rather it’s an engineering class that uses sophisticated mathematicso 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

5. 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 ENGR25o When in Doubt GRAPH it. If you don’t know when to doubt, GRAPH it ANYWAY

6. PUT IN the TIME

3 Applies to students 21 years of age or older


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 3906o The LIBRARY

How to Study Like a College Student - EXTRA CREDITStudents 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 EquipmentRequired

Others As Announced by the Instructor during the Course of the Semester

AttendanceGrade-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 Sets1. All Lab Problems will be accomplished on the Mastering Engineering OnLine Homework

& Learning System as described in the “Course Logistics” section of this syllabus2. 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).

Lab Exercises will be assigned on as indicated on the course schedule

Coursework Collaboration Working in groups during the Lab-period to complete Lab Problem Sets is fully

acceptable. Formation of informal, outside of class study groups is encouraged. However, each student must turn in his/her own LPS homework assignment Journal.

Grading Policy (Also available in “Mastering Engineering”) Number of answer attempts per question is: 6 You gain credit for:

o Correctly answering a question in a Parto Correctly answering a question in a Hinto Not opening a Hint (2% bonus)

You lose credit for:o Exhausting all attempts or giving up on a question in a Part or Hint Incorrectly

answering a question in a Part or Hint Late submissions: reduce the score for any item completed late by 1% for each hour

late, but never by more than 50%. The score is reduced for the whole item even if some parts are finished on time.

Hints are helpful clues or simpler questions that guide you to the answer. Hints are not available for all questions.

o There is no penalty for leaving questions in Hints unanswered. Grading of Incorrect Answers before the last attempt:

o You lose 100%/(# of options - 1) credit per incorrect answer on multiple-choice and true/false questions.

o You lose 3% credit per incorrect answer on questions that are not multiple-choice or true/false.


HomeworkAny 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 JOURNALSSince 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, paper-retaining 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 paper-

retaining 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

Copies of the CoverSheet will be provided before HWJ-1 is due The HWJ CoverSheet MSWord File may Also be DownLoaded from the

Course WebPageo 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.

MiniQuizzes40-50, 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 MQo 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.

o 3 Points → The student arrives at the correct result AND Demonstrates UNDERSTANDING of the course material presented

ExamsExams 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 OKo 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 CourseAfter 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 W-earning 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


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“All students are responsible for complying with college and district regulations and for meeting the appropriate college requirements. The College has an obligation to maintain conditions under which the work of the college can go forward freely, in accordance with the highest standards of quality, institutional integrity and freedom of expression. In joining the academic community, the student enjoys the right of freedom to learn and shares responsibility in exercising that freedom. Therefore, a student is expected to conduct himself or herself in accordance with standards of the college.

The minimum sanction for misconduct shall be removal of the student from Class for the remainder of the class period

Please refer to pages 67-71 of the 2014-2016 Chabot College Catalog http://www.chabotcollege.edu/academics/catalog/Catalog2014-16.pdf, or on the Student Services website on student conduct: http://www.chabotcollege.edu/studentservices/student_conduct.asp for detailed information on the Standards of Student Conduct expected of all students.”

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 Quietlyo Do NOT, repeat, do NOT walk in front of the PowerPoint Projector Image

Pagers, Cell Phones, Handheld Computers, and Similar Devices: Must be set to a NON-AUDIBLE 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 TOLERATEDAny 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
