4 lecture movies are placed on this HP.

These lectures are about basic knowledge of structural mechanics,

please take a lecture from lesson 1 to 4.  

These lectures are necessary for bridge design, but if you already know the contents below,

1.  Stress,Strain and Hooke's Law

2.  Bending Moment

3.  Bending Stress of Beam

4.  Second Moment of Area and Section Modulus

you don't need to take these lectures.

Lesson 1 : Stress,Strain and Hooke's Law

Lesson 2 : Bending Moment

Lesson 3 : Bending Stress of Beam

Lesson 4 : Second Moment of Area and Section Modulus
