1. Mechanical, Civil Engineering and Bridges

2. What is Mechanical and Civil Engineering?
They are the engineering disciplines that apply mechanics, kinematics, thermodynamics, material science and structural analysis to build structures (civil), or tools and machines (mechanical).

3. Forces and beam stress Lateral and vertical stress (bending force)
Torsional stress (twisting force)
Compression stress (crushing force)
Tensional stress (tearing force)
Shear stress

4. Beam bridge One of the oldest types
Relies on resistance to vertical stress

5. Sectional beam bridge
Relies on resistance to vertical (beams) and compression (piers) stress
Girder bridges can be considered a type of this bridge

6. Suspension and cable-stayed bridges
Rely on resistance to tension (cables) and on compression (pylons)

7. Truss bridges
They rely on resistance to tension and compression stress

8. A taxonomy of bridges by the principle forces employed

9. Good and Bad Engineering
