Course Description

In this course, following topics are taught:
(1) Stress and strain; Hook’s law; Stress-strain curves
(2) Deformation induced by weight; Stress and deformation induced by centrifugal force; Statically indeterminate problems; Thermal stress; Trusses
(3) Bending of beams; Shear force and bending moment; Bending stress; Deflection of beams

Course Objectives

Strength of materials is the application of mechanics to design components of machines and structures. This course aims to teach definitions of stress and strain, stress and deformation of the components under uniaxial loading, and bending of beams, and to provide students with an understanding of the way in which engineers design mechanical components that can meet specified requirements.

Grading Policy

Your overall grade in the class will be decided based on followings:
-　　Midterm examnination (20%)
-　　Term-end examnination (40%)
-　　Report (20%)
-　　Mini tests in the lesson (20%)

We will give feedback by returning the previous mini test and comment on the answer during class. In addition to returning the midterm exam, special problems including guidance at the Learning Support Office will be imposed on those who are not performing well in their grade.

Textbook and Reference

Requirements(Assignments)

Students should practice well on how to handle units and conversion methods in　dynamics learned in "Physics 1" etc. Please prepare a table of SI units andSI prefixes related to mechanics as a preparation for the first lesson and bring it to the class.
Please practice in order to be able to calculate scientific functions such as exponential function, logarithm function, trigonometric functions by using your own scientific calculator.
Please read the relevant part of the textbook before each lesson and check the relation with the contents of the last lesson. (1 hour)
After each lesson, please check the contents of the lesson again with help of textbooks and handouts distributed during the class. Please answer the examples and problems in the handouts. Also tackle the problems in the textbook that are instructed in the handouts. By repeatedly practicing, the ability to master the knowledge learned will be improved. (2 hours)
Detailed preparation for the subsequent lessons will be instructed in the class.

Note

We will do problem exercises during class, so be sure to bring a scientific calculator. A scientific calculator is also necessary for the examination. Please refrain from entering/leaving the class during classes.
As a result of the Midterm examination, students who are lack in mathematical skill in this course is be judged. These students need to take special training by using the Learning Support Office in order to raise the level of basic skills.
