Just as decimal fractions are unable to precisely represent some fractional values (such as 1/3 or Math.PI), binary fractions are unable to represent some fractional values.For example, 1/10, which is represented precisely by .1 as a decimal fraction, is represented by .001100110011 as a binary fraction, with the pattern "0011" repeating to infinity.
In the method of sections, a truss is divided into two parts . by taking an imaginary "cut" (shown here as a-a) through the truss. Since truss members are subjected to only tensile or compressive forces along their length, the internal forces . at the cut member will also be either tensile or compressive with the same magnitude.
