THERE IS NO EXTRA CREDIT AVAILABLE IN ANY FORM.  EVERYONE IS GRADED EQUALLY.  Yes, I understand that you had extenuating circumstances this semester, but so did everyonr else in the class.  That's why all of the weekly exams and rogue exams and the final exam were so easy, to take this into consideration.


Course Coverage:  The summer format for this class is grouped into fifteen 2-day groups. While these 2-day groups do not coincide with weeks, this is the most logical way to divide the material to agree with the accompanying McGraw Hill videos and homework problems. The homework and video assignments will be assigned by 2-day groups as listed below.

Semester Groups: Each semester contains groups of material listed above.  These are not weeks.  They span the duration of the class in order to agree with the McGraw Hill Homework materials.

 

Websites :     The McGrawHill Connect website will serve as one of two central resources for this class throughout the semester.  Their Connect website contains your electronic text book and provides the only interface where you can submit your homework.  You cannot email it to anyone nor put it on eCampus for grading.  It is only graded and recorded by McGraw Hill.  Membership in this website can be established by entering the code that you purchased at the bookstore or you can simply go to the McGrawHill website and join directly without interfacing with a bookstore.  It's also less expensive.  You can access a link to register for this section (CVEN 305/301 Lowery) on the McGraw Hill Connect website by CLICKING HERE.  <----- NOTE   McGraw Hill is still setting this up for us.

Daily Videos:

 

We used to have a set of video lecture reviews by Dr. Lynn Beason for both CVEN 221 (statics) and CVEN 305 (Strength of Materials). They are trying to resurrect them now, but it looks like they are really gone.  I will leave the instructions necessary to get to them below, just in case they show up.

 

Below are instructions to get to the videos (they still work for CVEN 221 Statics):  

(a) In browser, go to  vimeo.com; 

(b) Sign up for a FREE account (DO NOT PAY); 

(c) Login to vimeo with your sign-in account information; 

(d) In top right search box, type “engineering plain and simple”; NOTE!  There are 2 little magnifying glass search boxes on this screen.  You must use the upper one about 2 inches to the right of the word UPGRADE.  NOT the one next to the right edge of the scrre lower down!  Jackasses.

(e) Under ‘show results for’ on top left, click ‘people’; 

(f) Then click on icon for "engineering plain and simple"; 

(g) Then under “more” on top left, click on “showcases” (these are basically the chapters); 

(h) Now you can see all of the videos.  Sadly, although all the 221 Statics are there, only a few of the 305 videos made it.  The videos are loaded upside down.  There are a few 305 on the first page, then the LAST 221 page appears when you click a tab on the bottem of the page to see more.  After clicking about 20 times you get to the beginnig of the 221 videos and have to work your way back up.  Jackasses,

 


Weekly Quizzes:
Weekly quizzes will be administered on most Fridays.  Rogue quizzes will be given on any day at random, including Fridays (sometimes two quizzes on one day.).  The questions that appear will be inspired by homework problems that are due up to and including (1) material presented up to one class before the weekly quiz, (2) problems that are covered in class, and (3) materials from statics. 

YOU MUST BRING 8 1/2" x 11" PAPER WITH YOU TO CLASS EVERY DAY ON WHICH TO WORK EXAMS FOR SUBMISSION TO eCampus.
  YOU SHOULD GO AHEAD TODAY AND MAKE SURE THAT YOU CAN PHOTOGRAPH AND EMAIL A PERFECTLY LEGIBLE PROBLEM SOLUTION TO YOURSELF FROM A PIECE OF PAPER.  YOU WILL HAVE TO USE A VERY SOFT PENCIL OR DARK PEN AND EMAIL IT TO YOURSELF.  IF YOU CAN'T READ THE EMAIL COPY YOU SEND TO YOURSELF, WE WON'T BE ABLE TO READ IT EITHER.  Usually we can't read them because they are too dark! 

 

We don't want to force you to use any specific software, but some do a much better job of making a legible copy than others.  One of my students suggested Cam Scanner to me and I loved it.  Until I read that they had been hacked and someone they were selling my information to (which they ALL do - that's how they can give it to you "free") was playing fast and loose with the data. Like Facebook does.  Like Google does.  Like everything out there that's "free" does.  Cam Scanner has since fixed this.

 

When you take a quiz you do not have to copy all of the given and required information, and figures from the quiz but you will be expected to present a neat, legible, complete solution that contains any new figures and free body diagrams, units, and appropriate sign conventions required to make sense of your solution.  Your solution MUST be presented in a logical and methodical manner.  Please note that if your solution presentation is not clear and neat, points will be deducted.

Other Comments:

I am told that when submitting a weekly exam electronically via an eCampus submission box, you should always check that the file was uploaded successfully.  You can check this by downloading the file that you just submitted.  This helps prevent errors such as when students inadvertently click <Save> rather than <Submit>. 

eCampus work that was <Saved> but not <Submitted> can't be accessed by the graders and therefore cannot be graded.

ALSO, when submitting your homework to the McGrawHill homework site, be very careful NOT to SUBMIT your work until you are completely finished with it.  If you want to come back on a later day and work on it some more, just SAVE it.  Once you SUBMIT it, they think you are finished with it and they immediately grade it, including the last 2 or 3 problems you had planned on working on tomorrow, for which they just gave you a zero, and now its too late to change your mind.  TAKE THIS SERIOUSLY - I DON'T THINK YOU CAN UNDO IT. 

 

Resources available to the student - NOTE THAT MUCH OF THE LINKED INFORMATION FOLLOWING MAY HAVE TO BE MODIFIED DUE TO OUR FULL USE OF ZOOM AND DISTANCE EDUCATION TECHNIQUES THIS SEMESTER.  I AM STILL WORKING ON THOSE MODIFICATIONS:

  • Check Q-drop date on University Academic Calendar here
  • Typical point deductions you can expect on exams and pop quizzes
  • Video examples - Strength of materials problems and some by Dr. Beason
  • Answers to all questions after administration of final exams
  • Zachry Building Room Map
  •  

    The correct time (to the nanosecond)

    Course Schedule:

    Weekly minor quizzes:  Announced Weekly quizzes, when given, will be given during the last half of Friday's class (not always, but be prepared).  You must bring a copy of the 305 equation sheet attached here to all exams including the final exam.  There will also be Rogue (unannounced) minor quizzes during the semester, of which you can count up to 5 for grades.  Bring blank 8 1/2" x 11" sheets of paper every class day on which to take these quizzes.

    NOTES ON YOUR HOMEWORK:
    The homework assignments may have to be modified from that shown below, depending on our progress during the semester.  Please check the list for changes each day before you work them.  Also note that you MUST submit your answers before the deadline due date stated.  

    Notes on required viewing of videos:

    Quite a few of the homework problems normally assigned in this class have been dropped and replaced in favor of viewing some videos before coming to class.  These video assignments can be accessed by going to http://www.michaelsbrackin.com/cven305/.  The password is "videos" and is case sensitive.  They are also listed in the Video column below.  In each case, you should print out the notes, and then view the videos that follow the notes.  Again, in my case I have to use Firefox to view them.  I am told Chrome also works.  IE may work for you if Flash works on your computer.  If you install Flash BE SURE to unclick their "Optional Offer" trash before installing it.

     

     

    Homework:    All homework is accessed through the McGrawHill website identified above.  Your answers must be submitted through this website.  This is the only way that you can receive credit for the assigned homework.  The homework is to be submitted to and will be due as indicated on the McGrawHill website.

     

     I would advise you to assemble all of the numbered calculation sheets for each assignment in a homework notebook.  This notebook will be a very valuable resource as you prepare for the comprehensive final.  In addition, you MUST bring your problem solution with you should you need help with it during office hours or with the T.A.

     

    Attendance at Minor Quizzes and Final: It is your responsibility to be aware of the dates and times of the weekly quizzes and the final exam.  Changes, if any, to the printed dates and times will be announced in class.  Information presented by the University regarding the timing of the final exam supersedes anything printed herein.

     

    A university excused absence is required to justify an absence from a weekly quiz or the final exam at the announced time and place as defined below.  A doctor’s note must include a statement that you could/cannot appear for valid medical reasons.  The mere fact that you happened to be in a doctor’s office at the time of the examination is not sufficient.  The instructor should be notified of any impending absences well in advance of the scheduled date if possible.

     

    Do not attempt to postpone a quiz/exam on the day that it is scheduled.  It will be extremely hard to locate the instructor on the day of the quiz/exam because they will be involved in final preparations for the quiz/exam.

    For authorized absences, the instructor can chose to either give a makeup or exclude the missed material from the final grade calculations at their discretion. The make-up day for all missed quizzes is scheduled for later in the semester when hopefully no one later will ned it.  That date is as yet to be determined.

     

    No credit will be given for unauthorized absences.


    E
    xcused Absences (excerpt from Student Rules:)

    http://student-rules.tamu.edu/

     

    7.1 The student is responsible for providing satisfactory evidence to the instructor to substantiate the reason for absence. Among the reasons absences are considered excused by the university are the following: (1Muster)

    7.1.1 Participation in an activity appearing on the university authorized activity list. (see

    List of Authorized and Sponsored Activities)

    7.1.2 Death or major illness in a student’s immediate family.  Immediate family may include:  mother, father, sister, brother, grandparents, spouse, child, spouses child, spouses parents, spouses grandparents, stepmother, step-father, step-sister, step- brother, step-grandparents, grandchild, step-grandchild, legal guardian, and others as deemed appropriate by faculty member or student’s academic Dean or designee.

    7.1.3 Illness of a dependent family member.

    7.1.4 Participation in legal proceedings or administrative procedures that require a student’s presence.

    7.1.5 Religious holy day. (See Appendix IV.)

    7.1.6 Injury or Illness that is too severe or contagious for the student to attend class.

    7.1.6.1 Injury or illness of three or more days. For injury or illness that requires a student to be absent from classes for three or more business days (to include classes on Saturday), the student should obtain a medical confirmation note from his or her medical provider. The Student Health Center or an off-campus medical professional can provide

    a medical confirmation note only if medical professionals are involved in the medical care of the student. The medical confirmation note must contain the date and time of the illness and medical professional’s confirmation of needed absence.

    7.1.6.2 Injury or illness less than three days. Faculty members may require confirmation of student injury or illness that is serious enough for a student to be absent from class for a period less than three business days (to include classes on Saturday). At the discretion of the faculty member and/or academic department standard, as outlined in the course syllabus, illness confirmation may be obtained by one or both of the following methods:

    a.   Texas A&M University Explanatory Statement for Absence from Class form available at  http://attendance.tamu.edu.

    b.   Confirmation of visit to a health care professional affirming date and time of visit.

    7.1.6.3 An absence for a non-acute medical service does not constitute an excused absence.

    7.1.7 Required participation in military duties.

    7.1.8 Mandatory admission interviews for professional or graduate school which cannot be rescheduled.

    You will be expected to comply with both 7.1.6.2.a and 7.1.6.2.b to receive an excused absence.

    Academic Integrity Statement:

     

    An Aggie does not lie, cheat, or steal or tolerate those who do.”  Students are expected to understand and abide by the Aggie Honor Code presented on the web at: http://aggiehonor.tamu.edu  No form of scholastic misconduct will be tolerated. Academic misconduct includes cheating, fabrication, falsification, multiple submissions, plagiarism, complicity, etc.  These are more fully defined in the above web site.  Violations will be handled in accordance with the Aggie Honor System Process described on the web site.

     

    Unless specifically allowed in advance by the instructor, all assignments and homework in this class are expected to be completed based on individual effort. Copying the work of others, including a solutions manual, is a violation of Texas A&M Aggie Honor Code, Cheating.

     

    Upon accepting admission to Texas A&M University, a student immediately assumes a commitment to uphold the Honor Code, to accept responsibility for learning, and to follow the philosophy and rules of the Honor System. Students will be required to state their commitment on examinations, research papers, and other academic work. Ignorance of the rules does not exclude any member of the TAMU community from the requirements of the processes of the Honor System.
