Civil engineering basic units

 MUST KNOW THIS UNITS:

          Area                = m^2

          Volume           = m^3

          Stress              = kN/m^2

          Strain              = No units

          Moment          = KNm

          Force               = KN

          Deflection       = mm

          Density            = kN/M^3

          Specific gravity = no units

          Discharge          = m^3/second

Area

    Two dimensional

Volume

       Three dimensional

Stress

     Load / area

Strain

  

       Change in length/original length

Moment

         A force act on system the object is turn or move 

Force

       Inter action between two object

Deflection

          A force is acting on a object. That object is change to original state to another statue

Density 

         Mass/volume

Specific gravity

          Specifically gravity = unit weight of any fluids/unit weight of water
