HOMEWORK GUIDELINES:

Only a small sampling of problems from the homework assignments will be collected and graded. Theproblems to be collected will be selected on a random basis and announced at the time homework is due. Thedate that homework is due will be announced at least one class period in advance. Often, the class periodbefore homework is due will be used to answer questions on the assignment to be collected. For assignmentslabeled as homework, collaboration is allowed. For assignments labeled as quiz, whether they be in-class ortake-home, collaboration is not allowed and any evidence of such will be treated as academic dishonesty.

1. Occasionally, an additional problem will be assigned, which will be collected and graded.

2. Homework must be done on Engineering Calculation paper. Where applicable, free body diagrams should beincluded. Use a straight edge or paper grid to draw clear, concise free body diagrams. Proper SF and unitsshould be used at all times.

3. Multiple problems per page are permissible provided that:a) a given problem, requiring less than one page, does not start and end on different pagesb) the start and end of a given problem are clearly defined

4. Number all pages and put your name on every page. The first page title block should look like this:

MCHT 213 Sect__ Hw #1: 1-1 to 15, 29, 37, etc Your Name Pg 1/__

5. Work neatly. If I cant read it, or if I have trouble following the flow of the solution, it will be marked wrong.

6. Follow HW format: Problem #: Given: Find: Solution: (include FBD)

GENERAL COMMENTS:

- Attendance Policy: A student should attend every class for which the student is scheduled and should be heldresponsible for all work covered in the courses taken." Significant (3 or more) unexcused absence may result in half a lettergrade reduction. Students who fail to attend will not generally be allowed to make up quizzes or exams unless a prior

arrangement has been made. Absences such as athletics travel notice, ROTC notice, family emergencies, etc., must besupported by written documentation prior to class. Note that in case of illness the student is responsible to notify theinstructorbefore the class begins and to show evidence that medical attention was obtained. (See Policies and Rules forStudents on the PSU website at http://www.psu.edu/ufs/policies)

- Makeup Policy: Quizzes will be made up only if the makeup is arranged before the scheduled quiz period, and only in thecase of an excused emergency.

- Academic Integrity: Penn State Erie puts a very high value on academic integrity, and violations are not tolerated.Academic integrity is one of Penn States four principles to which all students must abide. Any violation of academicintegrity will receive academic and possible disciplinary sanctions, including the possible awarding of an XF grade which isrecorded on the transcript and states that failure of the course was due to an act of academic dishonesty. All acts ofacademic dishonesty are recorded so repeat offenders can be sanctioned accordingly. Students are encouraged to review

more information on academic integrity which can be found at: http://www.pserie.psu.edu/faculty/academics/integrity.htm

- Cellphones have become a growing problem in schools, considered nuisance items because of classroom disruptions.Please turn off cell phones while in class and absolutely no text messaging allowed during lectures. Failure to comply willresult in an absence from class. Three or more unexcused absences may result in half a letter grade reduction for your finalgrade.

Note to students with disabilities: Penn State welcomes students with disabilities into the University's educational programs.If you have a disability-related need for modifications or reasonable accommodations in this course, contact the DisabilitySpecialist in the Office of Student Affairs, Room 115 Reed Union Building, 898-6111.

- Relationship of course to program outcomes: MCH T 213 contributes to the following MET baccalaureate degreeprogram outcomes:[1] Students should be able to identify, analyze, and solve technical problems in the areas of materials, manufacturing

processes, mechanics, strength of materials, and in the fluid and thermal sciences.[2] Students should be able to use appropriate computer technologies during the solution of applied engineering problems

[3] Students should be able to integrate the basic CAD systems, manufacturing knowledge, and design techniques neededfor successful product realization[5] Students should be able to identify and use appropriate methods to validate solutions to engineering problems.[8]Students should be able to identify social, economic, safety, quality, reliability, and ethical issues in an engineering

technology problem and demonstrate that their solution to the problem addresses these issues.

- Course Objectives: After completing this course, students should be able to:

1. Determine the internal reactions of rigid, static members.

2. Identify and determine normal, shear, and bearing stresses from direct loadings on a member.

3. Understand and use the relationships of stress, strain, elastic modulus, Poissons Ratio, material strengths andfactors of safety to analyze and design simple members.

4. Determine thermal expansion/contraction and/or thermal stresses when analyzing and designing members.

5. Analyze and design circular shafting based on angular twist.

6. Analyze and design simple, thin-walled spherical and cylindrical pressure vessels.

7. Determine beam stresses and beam deflections and safely design beams for strength and stiffness requirements.

8. Draw shear and moment diagrams.

9. Analyze beams for transverse shear.

10. Analyze and safely design simple columns with minor/major axis bracing.

11. Analyze and safely design joints and fasteners.

12. Determine stresses from 2-D combined loadings and use stress elements to represent the results.

13. Determine principle stresses and maximum shear stress from 2-D combined loadings and use Mohr?s Circle todetermine orientations of the principle stress element and the maximum shear stress element.

14. Use hand calculations to verify a project using a spreadsheet program.
