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
Good and Bad Engineering
