Mechanical, Civil Engineering and Bridges What is Mechanical and Civil Engineering?
They are the engineering disciplines that apply mechanics,kinematics, thermodynamics, material science andstructural analysis to build structures (civil), or tools andmachines (mechanical). Forces and beam stress Lateral and vertical stress (bending force)
Torsional stress(twisting force) Compression stress(crushing force) Tensional stress(tearing force) Shear stress Beam bridge One of the oldest types
Relies on resistance to verticalstress Sectional beam bridge Relies on resistance tovertical (beams) andcompression (piers) stress Girder bridges can beconsidered a type of thisbridge Suspension and cable-stayed bridges
Rely on resistance to tension(cables) and on compression(pylons) Truss bridges They rely on resistance totension and compressionstress A taxonomy of bridges by the principle forces employed
