Relationship between internal stresses and deformations produced by external forces acting on deformable bodies, and design principles based on mechanics of solids: normal stresses, shear stresses, and deformations produced by tensile, compressive, torsional, and bending loading of members; beam deflections; elastic energy and impact; multi-dimensional stress states; buckling of columns.

Big Idea:

Solid materials deform and break. The extrinsic relation of force and displacement is governed by intrinsic material measures of stress and strain. The challenge is to connect the extrinsic to the intrinsic.

There is no required textbook for this class. However, these texts are very useful

• R. C. Hibbeler, Mechanics of Materials, 9th edition, Pearson, Prentice Hall, 2014.
• F. B. Beer, E. R. Johnston, J. T. DeWolf, and D. F. Mazurek, Mechanics of Materials, 7th edition, McGraw-Hill, 2015.
• R. R. Craig, Mechanics of Materials, 3rd edition, John Wiley & Sons, 2011.
• S. Timoshenko, History of Strength of Materials, Dover Civil and Mechanical Engineering, 1983.

The total score for the course is computed with the following weights:

Retake quizzes: Optional retake quizzes are available in the week following each first-chance quiz. If you choose to take the retake quiz, the quiz score will be 90% of the higher scores + 10% of the lower score (0.9*max(first_chance_score, retake_score)+0.1*min(first_chance_score, retake_score)). If you do not take the first-chance-quiz, then your score will be 90% of the retake score.

Quiz0: This review of statics is worth 0.5% of the total grade, and will not include a retake option or a quiz review session.

Discussion: Grade is computed as the product of participation and PL scores. The lowest discussion grade of the semester will be dropped.

Lecture attendance: The 6 lecture attendance grades (iclicker) will be dropped.

Online Lecture (Section ONC): Lecture attendance does not contribute toward final grades. The percentages shown above will be increased proportionally (by dividing by 0.95) to make up for the lack of iclicker scores.

The total score s corresponds to final grades as follows.

97% ≤ s < 100%	A+	93% ≤ s < 97%	A	90% ≤ s < 93%	A-
87% ≤ s < 90%	B+	83% ≤ s < 87%	B	80% ≤ s < 83%	B-
77% ≤ s < 80%	C+	73% ≤ s < 77%	C	70% ≤ s < 73%	C-
67% ≤ s < 70%	D+	63% ≤ s < 67%	D	60% ≤ s < 63%	D-
s < 60%	F
