COURSE DESCRIPTION:
The course provides a study of the fundamentals of solid mechanics of deformable bodies. The engineering structures covered in this course are determinate and indeterminate assemblies of tension members, columns (including buckling), beams (flexural members), shafts (torsional members), and thin-walled pressure vessels (tanks). The course also contains an introduction to common categories and types of engineering materials and their failure mechanisms. The importance of safety factors and their application in the Allowable Stress Design philosophy is emphasized throughout the course, leading to an enhanced awareness of the professional and ethical responsibilities inherent to the role of the engineer.
|
SUMMARY OF COURSE CONTENT:
Fundamentals of stresses and strains; material properties; axial, torsional, bending, and combined loadings; determinate and indeterminate analysis; stress at a point; stress transformations and Mohr’s Circle for stress; beam deflections; thin-walled pressure vessels; columns and buckling; stress concentrations.
|
LEARNING OUTCOMES:
Upon successful completion of this course, the student will be able to:
1.Memorize and apply the various sign conventions that comprise the basic language of solid mechanics.
2.Analyze engineering structures and create appropriate free-body diagrams as required to solve problems.
3.Analyze members by statically determinate or indeterminate methods as required to solve problems.
4.Interpret and correctly apply the stress and strain equations for axial, flexural, and torsional members.
5.Interpret and apply the deformation equations for axial and torsional members; derive and apply the deformation equations for flexural members.
6.Label correct stress magnitudes and senses on the 2D stress element and the 3D stress cube.
7.Employ Mohr’s Circle to transform a state of stress to any angular rotation; determine principal stresses, maximum in-plane shear stress, and absolute maximum shear stress.
8.Interpret stress-strain diagrams for a given material and describe its behavior using proper terminology (yield stress, fracture stress, Young’s modulus, ductility, etc.).
9.Design engineering structures and/or members using the Allowable Stress Design philosophy.

GRADING POLICY
-ASSESSMENT METHODS:
| Assignment | Guidelines | Weight |
| Homework | Homework will be assigned and graded online using Mastering Engineering (ME). Be sure to purchase ME access with your electronic or hardcopy textbook. Homework will count for 15% of the course grade. | 15% |
| Exams | In-class exams will be given weekly. The exam average will count for 60% of the course grade. | 60% |
| Final Exam | The Final Exam is comprehensive and optional. For those who choose to take the Final Exam, it will count for 25% of the course grade. | 25% |
-ASSESSMENT CRITERIA:
AWork of this quality directly addresses the question or problem raised and provides a coherent argument displaying an extensive knowledge of relevant information or content. This type of work demonstrates the ability to critically evaluate concepts and theory and has an element of novelty and originality. There is clear evidence of a significant amount of reading beyond that required for the c
BThis is highly competent level of performance and directly addresses the question or problem raised.There is a demonstration of some ability to critically evaluatetheory and concepts and relate them to practice. Discussions reflect the student’s own arguments and are not simply a repetition of standard lecture andreference material. The work does not suffer from any major errors or omissions and provides evidence of reading beyond the required assignments.
CThis is an acceptable level of performance and provides answers that are clear but limited, reflecting the information offered in the lectures and reference readings.
DThis level of performances demonstrates that the student lacks a coherent grasp of the material.Important information is omitted and irrelevant points included.In effect, the student has barely done enough to persuade the instructor that s/he should not fail.
FThis work fails to show any knowledge or understanding of the issues raised in the question. Most of the material in the answer is irrelevant.
-ATTENDANCE REQUIREMENTS:
Attendance is not taken in the course. However, students that miss even a single day of lecture are likely to fall behind in the course material. Each concept introduced in the course builds on mastery of previous concepts. The best strategy for success in this course is to attend every single lecture diligently.
Please refer to the university catalog for the attendance and absence policy.

ACADEMIC HONESTY
As stated in the university catalog, any student who commits an act of academic
dishonesty will receive a failing grade on the work in which the dishonesty occurred.
In addition, acts of academic dishonesty, irrespective of the weight of the assignment,
may result in the student receiving a failing grade in the course. Instances of
academic dishonesty will be reported to the Dean of Academic Affairs. A student
who is reported twice for academic dishonesty is subject to summary dismissal from
the University. In such a case, the Academic Council will then make a recommendation
to the President, who will make the final decision.

STUDENTS WITH LEARNING OR OTHER DISABILITIES
John Cabot University does not discriminate on the basis of disability or handicap.
Students with approved accommodations must inform their professors at the beginning
of the term. Please see the website for the complete policy.
