Class Objectives
/Class Outline Mechanics of Materials is one of fields to study Solid mechanics. This subject is positioned in the Mechanical Engineering as one of important academics. In the Mechanics of Materials, infinitesimal, one-dimensional and elastic deformation obeying Hookean law.

1) Learning about fundamental theories to calculate stress, strain, deformation, etc. when external forces are applied to a body including solid materials and structures.

2) Leaning about how to obtain stress, strain, deformation when tensile and compressive axial forces are applied to a bar.

3) Learning about how to calculate shear stress, strain and angle of twist when torsional moment is applied to a shaft.

4) Learning how to calculate bending stress, shear stress, deflection and deflection angle when concentrated and distributed forces are acting on beams.

The educational goal can be refered in the specification of individual program.

Class Schedule lesson1 Introduction
lesson2 Stress and strain (Definition of stress and strain, Stress-strain relationship)
lesson3 Stress and strain (Hooke's law, Allowable stress and safety factor)
lesson4 Axial force
lesson5 Axial force (Continued)
lesson6 Torsion
lesson7 Tosion (Continued)
lesson8 Midterm Examination
lesson9 Bending stress (Types of supports and external forces, Shearing force and bending moment)
lesson10 Bending stress (Relationship between shearing force, bending moment and distributed force, Bending stress)
lesson11 Bending stress (Theorems on the first and second moments of cross-section)
lesson12 Bending stress (Beams with uniform strength, Shear stress of beams)
lesson13 Deflection by flexure (Governing differential equation on deflection, Cantilever)
lesson14 Deflection by flexure (Simply-supported beam, Method of superposition)
lesson15 Deflection by flexure (Statically-indefinite beams)

Midterm and final examinations

[Homework]
When a lecture achive the end of chapters, students do homework on their own and submission of homeworks is required in the beginning of next class.

There is a possibility to let students submit their notebooks because taking notebooks is required.

Loose-leaf notebooks and report pads cannot be accepted for the submission of the notebooks.

Suggestions on
Preparation and
Review 1) Reviewing statics learned in the first grade.
2) Reading textbook and solving example problems to prepare for classes
3) Reviewing topics learned in the each class
4) Provided problems in the end of each chapter on the textbook are solved on their own.

Requirements

Grading Method Mainly, a total evaluation includes scores of the midterm and final examination, homeworks, answers to quizes in classes, submission of notebook. 60 % of the evaluation is done by the final examination, 20% of that is done by the midterm exam and 20 % of that is done by the others. Students who take a grade over 60% of the evaluation can pass.
