RECTANGULAR SECTION        
  Calculate the area moment of inertia and section modulus of a Rectangular-Section,  
   about x-axis and y-axis .  Its unit of dimension when working with the  
  International System of Units is meters to the fourth/third power,  
   m4/3, mm4/3, cm4/3or inches to the fourth/third power, in4/3,  
   when working in the Imperial System of Units.
