Strength of Materials I

Strength of materials is the main foundation for both Mechanical and Civil Engineering in the upcoming design courses. Engineering design concepts are integrated into the Strength of Material course. Methods in this class are learned for determining the stresses, strains and deflections produced in various members produced by applied loading. As a main core of the Mechanical Engineering discipline this course is to provide training in a fundamental subject (mechanics and structural) necessary for careers mechanical, civil and related engineering fields. This course covers external/internal forces and conditions of equilibrium in structures and/or machines statically indeterminate or determinate subjected to axial, bending, and torsional loads and their mechanical response, as well as the following topics: stress and strain concepts, axial load, statically indeterminate axially loaded members, thermal stress, torsion, angle of twist, statically indeterminate torque-loaded members, bending, eccentric axial loading of beams, transverse shear, shear flow in build-up members, combined loadings, stress and strain transformation, deflection of beams and shafts, statically indeterminate beams and shafts, the relationship between stress and strain on deformable solids.

GRADING POLICY
	Class activity: 100% Home Work 30% Quizzes 50% Project 20% Tests: 100% Midterm exam 50% Comprehensive final test 50% ___________________________________ Total of each part 100% No reference materials or books will be allowed in any tests or final exam Homework and projects will be due at the beginning of the next class period unless otherwise specified. No “make-up” or “extra credit” assignments will be given
GENERAL POLICIES
	Attendance Policy: Regular and punctual attendance in every class is mandatory. The penalty for more than 3 unexcused absences will result in 5 % reduction in the tabulated score for calculation of final grade. More than 4 unexcused absences will lead to dismissal from the course. Attendance will be taken at the start of each class session. If you are not present when attendance is taken, you will be counted absent for that day. For an absence or a tardiness to be excused, you must inform the instructor ahead of time. If you indeed have to miss a class due to unavoidable circumstances, you are responsible for all the announcements and materials presented in the class. Class Disruption Policy: 1. Cell phones must be turned off or put in the vibration mode during class or tests. 2. You must leave the class room to answer the cell phone calls. 3. Cell phones cannot be used during the class for text messaging. 4. Cell phones cannot be used during the tests or final examination in lieu of calculator. 5. Use of beepers, pagers, radio or earphones are not permitted during the class or tests. 7. Violation of any of the above will result in a deduction from the tabulated score for calculation of final grade.
Academic Dishonesty Policy
	It is illegal to falsify and/or otherwise misrepresent oral and/or written communications by the instructor. There are many items that fall under this category which may include but not limited to the following: i) Statements concerning dates assignments are due ii) Signature requirement iii) Bonus opportunities iv) Changes in course assignments v) Changes in grading protocol The intentional and/or otherwise misrepresentation(s) or erroneous disclosure(s) of information presented in the classes, lectures, labs and /or other consultations for personal gain represents unethical behavior and/or academic dishonesty in an attempt for personal gain. Such behavior(s) may possibly represent slander, and/or libel, and/or defamation of character which may possibly have legal ramifications. Students are encouraged to ask questions and consult each other while working on their assignments. However, sharing the work electronically or copying another student’s work by any method is strictly forbidden. If two or more students are found to share the same copy of a project, each will receive a grade of ‘0’ for that project. This penalty applies even if other students copied a student’s work without his/her permission. Therefore, it is very important that you safeguard your work, whether in printed or electronic form.
