• There is no make-up for missed class activities.

4. Exam Policy:

• The exams will consist of problem solving like the homework and are given on the scheduled dates (see homework and exam schedule).
• The final exam is a cumulative exam and will be given on the last day of the semester.

5. Missed Exam Policy:

• No exam make-ups will be given without proper documentation of the absence, such as doctor’s note, which should state clearly that the student was physically unable to attend class on that day.
• Simply put you need to have a very very good and documented reason.
• When a make-up exam is given, it is not the same exam given to the class.

6. Withdrawal Policy:

• This is the responsibility of the student.
• The instructor does, however, reserve the right to drop a student should he or she feel it is necessary.
• If a student decides to withdraw, he or she should also verify that the withdrawal is recorded before the Final Withdrawal Date. The final withdrawal day is  Monday 7/22.
• State law permits students to withdraw from no more than six courses during their entire undergraduate career at Texas public colleges and universities. With certain exceptions, all course withdrawals automatically count towards this limit. Details regarding this policy can be found in the ACC college catalog.

7. Student Discipline:

• Students enrolled in this course are expected to comply with the provisions of this syllabus and the Student Standards of Conduct.
• With the exception of scholastic dishonesty, violations of the Student Standards of Conduct will be reported to the Campus Dean of Student Services for disciplinary action.
• Any student suspected of scholastic dishonesty will meet in private with the professor to discuss the alleged offense(s) and review the evidence that supports the charge. After conferring with the student, the professor will dismiss the allegation or assess an academic penalty.
• A student will be informed in writing if an academic penalty is assessed. He or she should consult the Student Handbook for his/her rights and responsibilities.

8. General Course Policy:

This is a challenging engineering course for serious engineering students. You will need all of the 20 hours per week studying, solving problems,

studying again and preparing for the exams.

8 Policy on Incompletes:

A grade of incomplete should be reserved only for extreme cases meeting the following criteria.

1. The student has had a documented life event beyond their control that will prevent

them from completing the semester on time.

2. The student is in good standing (Grade of C or better at the time of the life event from (a).

3. The student has completed most of the material in the course.

Before assigning a grade of incomplete, the instructor and the student must agree to a plan

of action that includes a specific list of tasks to be completed by the student with a timeline

of completion. This plan needs to be approved by the department chair (or designee).

Incompletes must be resolved before the final withdrawal date of the following semester.

Students may request an Incomplete from their faculty member if they believe circumstances

warrant. The faculty member will determine whether the Incomplete is appropriate

to award or not. The following processes must be followed when awarding a student an I grade.

1. Prior to the end of the semester in which the I is to be awarded, the student must meet

with the instructor to determine a plan of action that identifies all of the assignments

and exams that must be completed prior to the deadline date. This meeting can

occur virtually or in person. The instructor should complete the Report of Incomplete

Grade form with the plan of action and send it to the department chair (or designee) to be approved.

2. Once approved, the faculty member will complete the form, including all requirements

to complete the course and the due date, sign (by typing in name) and then email it to the student. The student will then complete his/her section, sign (by typing

in name), and return the completed form to the faculty member to complete the agreement. A copy of the fully completed form can then be emailed by the faculty

member to the student and the department chair for each grade of Incomplete that the faculty member submits at the end of the semester.

3. The student must complete all remaining work by the date specified on the form above. This date is determined by the instructor in collaboration with the student, but

it may not be later than the final withdrawal deadline in the subsequent long semester.

4. Students will retain access to the course Blackboard or other LMS named here through the subsequent semester in order to submit work and complete the course. Students will be able to log on to Blackboard or other LMS named here and have access to the course section materials, assignments, and grades from the course and semester in which the Incomplete was awarded.

5. When the student completes the required work by the Incomplete deadline, the instructor will submit an electronic Grade Change Form to change the students performance

grade from an I to the earned grade of A, B, C, D, or F. If an Incomplete is not resolved by the deadline, the grade automatically converts to an F.

Approval to carry an Incomplete for longer than the following semester or session deadline is not frequently granted.

Important note on homework:
1. The solution of homework problems should be the result of your own work. Homework copied from another student, from a solution manual or from internet websites will not be graded and you will get a zero for that homework set.
2. If your homework solutions "looks a lot like the solution manual", then you are copying somebody else's work and you will get a zero for that homework. Plagiarism is against my rules, the department rules and the College rules. You risk being reported to the Dean of Students and being withdrawn from this course. Please consult the College Catalog for the College's Rules on Scholastic Dishonesty.
3. More importantly, to pass this course, a student must do well on the exams. Do the homework to learn the material and give yourself a chance to do well on the exams. Not doing so, you take this chance away.
4. Scholastic dishonesty is against the rules of this course, against the rules of the Department and the College.

These problems are intended as extra practice. Generally the homework does not give you
enough practice to master the concepts and become proficient at solving problems to the
point where you can do very well on the exams. The student is encouraged to do as many
of these problems as needed to master the subject. These problems are not to be turned in.
Note: I suggest that you try ALL the Preliminary Problems and Fundamental Problems
since the solutions and the answers of these are given in the back of the book. They are
good practice problems.

Steps to Success in this Course

The time you spend studying and doing homework is the single most important factor in determining how well you do in this class.

The following plan, if followed, will improve your chance of succeeding in this course.

The time requirement for this course is on average about 20 hours per week outside the classroom. Here are some suggestions on how it should be divided.

1. Form a study group.

2. Study ahead. You know the schedule, so study the subject before coming to class.

This is a quick (yet very important) study to gain familiarity with the subject. About 3 hours.

3. Divide the chapter in two halves.

4. Study the first half including the solved sample problems in the book and do half

of the homework problems of the first set. The solved sample problems are very

similar to the homework problems and are very helpful in teaching you the subject.

Note each chapter has two sets of homework problems. On your own with little help

from others, you should be able to do 70% of these problems. If you are not able

to do that, then your study was not good enough. Which sections are you having

difficulties with? Go back and study these sections. If you are having difficulty with

a problem from section 3 for example, go back and study section 3 and try to see if

there is a solved sample problem from that section. This study should be done first half of the week. About 5 hours.

5. Study second half of the chapter and do what you did for the first half. This should be done second half of the week. About 5 hours.

6. Summer session this protocol needs to be done twice a week.

7. List the three main ideas of the chapter. Do you have a good understanding of these ideas? Summarize each in a short paragraph, include FBD’s, and basic equations.

8. Write down the questions and the problems you had difficulty with and bring them up in class or come see me during office hours. Discuss these questions with your

classmates. One way or another, get your questions answered.

9. Come to class on a regular basis, listen, ask questions and participate.

10. Take all the exams.

11. Do not copy from the solutions manual or from Cheg or from anywhere online. These outlets do not teach you anything. They deceive you into thinking  you are learning. But you are not. It is the anti-learning.
